Salt dough ornaments are three ingredients you already own, and they go wrong more often than any craft this simple should. The dough puffs up and swallows the handprint. The edges brown while the middle stays wet. They come out hard on Sunday and soft again by Wednesday.
I worked out why because the ornament in question ended up on a page of a Christmas book, and a printed book cannot be corrected. It comes down to one number, and most recipes online get it approximately right for the wrong reason. Bake salt dough ornaments at 100C / 200F for two to three hours, roll to 5 mm, flip once, then leave them out overnight. After 27 years making things for children, this is still the craft I get asked about most in December. Not how to make it. Why it failed.

What do you need for a salt dough ornaments recipe?
Quick Answer: Flour, salt and warm water, in that order of quantity. Nothing else is required. This salt dough ornaments recipe also needs a rolling pin, a metal baking sheet, parchment paper, cookie cutters or a glass, and a drinking straw for the ribbon hole. The straw is the item people forget, and the one that cannot be added later.
| What | How much | Notes |
|---|---|---|
| Plain all-purpose flour | 1 1/2 cups | Plain only. Self-raising flour makes them puff |
| Table salt | 3/4 cup | Fine table salt, not kosher or flaky |
| Warm water | 1/2 cup | Add slowly, a tablespoon more at a time if needed |
| Ground cinnamon | A pinch | Optional. It smells like baking and darkens the dough |
Cheap flour is the right flour for salt dough ornaments, because nobody is eating them. The salt is doing real work: two parts flour to one part salt is the ratio that came out smoothest in the one comparison anybody has actually run, and it holds a printed detail better than a leaner dough does. The one substitution that ruins a batch is self-raising flour, which contains a raising agent, and that is the last thing you want in a dough that has to stay flat.

Quick Answer: Mix, knead, roll to 5 mm, cut, poke the ribbon hole, then dry low and slow. Plan two days: shaping and drying on day one, painting on day two. The drying is the long part and it is not negotiable, so start in the morning rather than after dinner.
Step 1. Mix dry, then add water. Stir flour and salt together, then pour the warm water in slowly while you stir. It will look too dry before it looks right. Work it with your hands before adding more liquid, because most doughs that feel wrong at this stage come together with kneading rather than water.
Step 2. Knead for five to ten minutes. This is the step children like and adults skip. Kneading pushes out the pockets of air that later become bubbles. You are finished when it feels like play dough and stops sticking to your hands.
Step 3. Roll to 5 mm, a shade under a quarter inch. Roll between two sheets of parchment, which stops it sticking and saves your worktop. Five millimetres is roughly three coins stacked. Thinner holds a shallower impression; thicker takes considerably longer to dry through.
Step 4. Cut your shapes and leave them where they are. Peel the excess away from around the shapes rather than lifting the shapes out, because lifting distorts them. For a handprint, press the hand into an open area first and cut around it afterwards. Small children do not aim their hands into a circle.
Step 5. Poke the ribbon hole now. Use a drinking straw, and blow the plug of dough out before the next one. Parents write to me about this step, always after the fact. There is no way to make a hole in a dried ornament without cracking it.
Step 6. Dry the salt dough ornaments at 100C / 200F for two to three hours. Slide the parchment onto a metal baking sheet and flip them once halfway. Then turn the oven off, take them out, and leave them somewhere dry overnight to finish.
Step 7. Paint on day two. Acrylic craft paint for older children, washable tempera for the ones who will be wearing it. Let the paint dry fully before threading ribbon.
What temperature do you bake salt dough ornaments at?
Quick Answer: 100C / 200F. Not 150C / 300F, and not the 250F / 121C most recipes print. The reason is the boiling point of water. Below it, water in the dough leaves as vapour and the ornament dries. Above it, the water inside turns to steam and inflates the piece from within.
Here is the part no recipe page explains. When water turns to steam it expands roughly 2000 times in volume. That expansion makes bread rise, which is wonderful in a loaf and ruinous in a flat ornament meant to hold a handprint. Every pocket of air left in the dough becomes a balloon.
A second threshold sits just above it. Browning comes from the Maillard reaction, which needs roughly 138C / 280F, and cannot proceed while the surface is wet. So above 138C / 280F your salt dough ornaments brown, and above the boiling point of water, 100C / 212F, they puff. At an oven set to 100C / 200F you are below both, which is why nothing happens except drying.
That is also why I never print one temperature scale alone. The most specific cause of ruined ornaments I came across was somebody reading a Fahrenheit number and setting it on a Celsius dial. A dial turned to 200 on a Celsius oven is 200C / 392F, not the 100C / 200F you wanted, and it will scorch a batch of salt dough ornaments in twenty minutes.
How long to bake salt dough ornaments
Two to three hours at 5 mm, flipped once, then overnight out of the oven. Handprints run longer because they are thicker, sometimes an extra hour. Judge by feel and colour rather than the clock: both sides the same pale shade, no give anywhere, and check the back rather than the front.
Why most recipes say 250F / 121C, and why I do not
Read five recipe pages and you will find 250F / 121C on most, and it looks like consensus. It is not. None of them reported testing it, cited another source, or gave a reason for the number. 250F / 121C is a round number on an American oven dial, and five people printing one convention is one convention, not five findings.
Look at where 250F / 121C actually sits. It is 21 degrees above boiling and 17 below the browning threshold, which predicts exactly what those pages describe, puffing that comes and goes with no browning to warn you. One says outright that puffing "sometimes happens randomly". It is not random. It is a setting balanced on the edge of a threshold nobody on that page had identified. 250F / 121C works most of the time. The ornament with your child's handprint in it is not a batch you get to repeat.
Why did my salt dough ornaments puff up?
Quick Answer: Almost always the oven was above 100C / 212F and the water inside turned to steam. The other causes, in order: self-raising flour instead of plain, dough rolled thick or unevenly, and air trapped by not kneading enough. Fix the temperature first, because it accounts for most of it.
One parent described it exactly right: "My ornaments are rising and erasing the handprints. Are they maybe too thin or is the oven too hot?" The oven was too hot. Another put a paw print in at 175C / 350F for half an hour on the day their dog was put to sleep, and got browning at the corners and bubbles under the surface. That one stays with me, because it was information somebody should have given them.
Puffing is the one failure here you cannot undo. Once steam has inflated the piece and the starch has set around it, there is no flattening it. If it puffed at 100C / 200F, check the flour bag. Self-raising flour catches people who have made salt dough ornaments successfully for years and then bought the wrong one.
Why are my salt dough ornaments still soft in the middle?
Quick Answer: The surface dried into a crust before the middle could lose its moisture. Too thick, not flipped, or baked on glass rather than metal. This is completely recoverable. Put them back in a low oven at 100C / 200F, or leave them out to air dry for a few more days, flipping so both sides are exposed.
A parent wrote: "I baked mine in a glass oven dish and the top was dry and hard but when I took it out of the glass the bottom on the ornament that was touching the glass was still soft." Glass insulates. Use a metal baking sheet with parchment on it.
A second version confuses people more, because it happens after the ornaments were definitely finished. Salt pulls moisture out of the air. That is what makes it a preservative, and also what makes an unsealed ornament go soft again in a damp room. One parent baked theirs four hours, painted them, sealed them overnight, and woke to soft ornaments. Seal an ornament that is not completely dry and you have not protected it, you have locked the water inside.
What goes wrong with salt dough ornaments, and what can you fix?
Quick Answer: Puffing, browning and cracking cannot be undone. A soft centre, a batch that went soft again, and a handprint not yet dried can all be rescued. Knowing which is which saves you throwing away a batch that was fine, and painting one that was not.
| Symptom | What caused it | How to prevent it | Can you fix it? |
|---|---|---|---|
| Puffed or bubbled | Oven above 100C / 212F, water flashed to steam | Bake at 100C / 200F; air dry a day first | No. Start again |
| Puffed at a low oven | Self-raising flour, or thick uneven dough | Plain flour only; roll evenly to 5 mm | No. Start again |
| Handprint rose and vanished | Puffing lifted the impression out | As above | Only if caught before drying |
| Browned edges | Above 138C / 280F, where browning begins | Stay at 100C / 200F; rotate the sheet | Cosmetically, with white paint |
| Hard outside, soft centre | Surface crusted; thick, not flipped, or on glass | Flip hourly; metal sheet; roll thinner | Yes. Low oven or longer air dry |
| Went soft again days later | Salt drew moisture from air, or sealed too early | Confirm bone dry; store airtight with silica | Yes if unsealed. Hard once sealed |
| Cracked while drying | Likely too much water, rolled thin, dried fast | Minimum water; 5 mm; low heat | No cleanly. Re-wetting worsens it |
| Cracked a year or two later | Moisture moving in and out in storage | Store somewhere dry and stable, not an attic | No. Glue only |
| Mould | Moisture in an unsealed piece | Dry fully, store dry | No |
Two rows deserve a caveat rather than confidence. Cracking and mould are the failures I found the least solid evidence for. The explanations are the conventional ones and they fit everything else here, but I found no source that had actually tested them, and I would rather say so.
Can you make salt dough ornaments without an oven?
Quick Answer: Yes, and it removes the puffing problem entirely, because the dough never gets near boiling point. Air-dried salt dough ornaments take one to seven days depending on thickness and how damp your house is. Turn them daily so both sides dry evenly. It is the right choice for classrooms and for anyone whose oven will not go low.
I cannot give you a reliable single number for how long it takes, and neither can anyone else. The reported range runs from overnight for thin shapes in a dry climate to a full week, and the variable that governs it is humidity, which not one source I read controlled for.
There is a hybrid I think is best. Air dry for a day, then finish at 100C / 200F for a couple of hours. The day out of the oven takes off the surface moisture, which is the moisture that causes trouble, and the low oven finishes the middle without drama. For a classroom this is the only version that works anyway: make them in one session, decorate in the next. If you are planning that session, the activity pack library covers the quiet half of the morning while the dough dries.
How do you make a salt dough handprint ornament?
Quick Answer: Press the hand into a large open piece of dough first, then cut around the print. Roll slightly thicker than for a cut-out shape. Allow longer drying. And make more than one, because salt dough ornaments break and the dough costs pennies.
The order matters more than anything else. It is tempting to cut a neat circle and ask the child to place their hand in the middle. Small children cannot aim, they wriggle, and you get three fingers over the edge. Press first into a big sheet, then cut around whatever you got.
If the dough will not take a clean impression it is too dry. Keep kneading, and add water a tablespoon at a time until it takes a print without cracking at the edges of the fingers. A salt dough handprint ornament needs longer than a cut-out shape because it is thicker. Write the year on it in pencil before it dries, because in four years you will not remember.
Is salt dough dangerous for dogs?
Quick Answer: Yes, seriously so, and this is where I want to give you numbers instead of a warning. A peer-reviewed review of 14 dogs that ate homemade salt dough found the lowest dose producing clear symptoms was 1.9 grams of dough per kilogram of body weight. For a 5 kg dog that is under 10 grams, which is one small ornament.
In that case series, published in the Journal of Veterinary Emergency and Critical Care, 12 of the 14 dogs showed clinical signs. Vomiting was most common at 64%, and seizures occurred in 29%. Every animal whose blood sodium passed 180 mEq/L had seizures.
The FDA puts it in kitchen units: a batch can hold up to a cup of table salt, which is 48 teaspoons, and half a teaspoon can make a 10 lb pet ill. Pet Poison Helpline says one or two ornaments can make a dog very sick, and adds a hazard the craft pages never mention: a baked ornament is hard and can be difficult to pass. Cornell's canine health centre lists them by name among its holiday hazards.
So keep dough off the floor while you work, hang finished salt dough ornaments high on the tree rather than the bottom branches, and remember that an ornament made five years ago is exactly as salty as the day you made it. If your dog eats one, call your vet rather than waiting.
Is salt dough safe for children to handle?
Quick Answer: Handling it is fine with supervision. Eating it is not, and there are two separate reasons that usually get muddled together. One is the salt. The other is the raw flour, which is a real food-safety issue rather than a technicality. Neither is a reason to skip making salt dough ornaments, and both are a reason to wash hands afterwards.
On the salt, the UK's National Poisons Information Service has the only quantified figure I could find. Around one gram of salt is enough to concern a 10 kg child, which works out at roughly four grams of homemade dough. Their director noted the taste is unpleasant enough that reported cases are rare, and also that the reassurance parents give each other online, that this is non-toxic, runs contrary to their advice. A lick is not a crisis. Handfuls would be.
The raw flour surprises people. Most flour is not treated to kill bacteria, and the CDC names this craft explicitly, advising against eating raw dough including "crafts made with raw flour, such as homemade play dough or holiday ornaments", and against letting children eat or play with it. In practice: supervision, no tasting, and washing hands and the worktop afterwards. I read a lot of pages that print a cheerful warning and cite nobody at all, and you deserve better than that.
How to seal salt dough ornaments, and whether you need to
Quick Answer: Not necessarily, and I cannot tell you which sealant is best because nobody has tested them properly. What I can tell you is that sealing an ornament that is not completely dry will ruin it, that spray acrylic has better first-hand support than brush-on varnish, and that plenty of people never seal at all.
The one documented account I found of what sealing does to salt dough is a failure. A childcare provider varnished a whole class set of handprint ornaments the children had made as gifts, and wrote afterwards that "some chemical reaction occurred and the varnish extracted the salt from the dough", and that the clear varnish dried cloudy, yellowish and cracked. In the same conversation two other providers said they had never sealed one in their lives and had ornaments still hanging decades later. Two more said a light acrylic spray from a can worked fine, which is a different product from brush-on furniture varnish.
That is the whole evidence base: one failure, some testimony, no comparison. So dry the salt dough ornaments completely, paint them if you want, then decide. If you do seal, test it on a spare piece from the same batch first, and never put an untested sealant on the keepsake one.
On how long they last, I am going to disappoint you deliberately. You will see confident numbers online: decades, a lifetime, fifty years. Not one is backed by anything except somebody's memory. What is clear is what destroys them, which is moisture moving in and out of the piece over years. Store them wrapped, somewhere dry and temperature-stable, away from an attic that bakes in summer and freezes in winter. That is the useful advice, and a number of years is not.

- Bake salt dough ornaments at 100C / 200F for two to three hours at 5 mm, flip once, then leave them overnight out of the oven.
- The reason is the boiling point of water. Above 100C / 212F the water inside turns to steam and inflates them. Above 138C / 280F they brown as well.
- 250F / 121C is the number most recipes print. It is a convention nobody tested, sitting just above boiling, which is why it puffs unpredictably.
- Plain all-purpose flour only. Self-raising flour puffs the dough regardless of temperature.
- Poke the ribbon hole in your salt dough ornaments before drying. There is no way to add it afterwards.
- Puffing, browning and cracking cannot be undone. A soft centre can always be rescued.
- Salt dough is a real hazard to dogs at about 1.9 g per kg of body weight, which is one small ornament for a small dog.
- Sealing is optional, and it is not a rescue for an ornament that is not fully dry.
Frequently Asked Questions
How long to bake salt dough ornaments?
Two to three hours at 100C / 200F for dough rolled to 5 mm, flipped once halfway, then left out overnight to finish. Thicker pieces and handprints take longer, sometimes an hour more. Judge by feel and colour rather than the clock: both sides the same pale shade, no softness anywhere.
Why did my salt dough ornaments puff up in the oven?
The oven was almost certainly above 100C / 212F, which turns the water inside the dough to steam and inflates it from within. The other common cause is self-raising flour, which contains a raising agent. Rolling thick or unevenly makes it worse. Puffing cannot be reversed once set, which is why the low oven matters.
Why are my salt dough ornaments still soft after baking?
The outside dried into a crust before the middle could. It happens with thick pieces, ornaments that were never flipped, and anything baked in a glass dish rather than on a metal sheet. It is fully fixable: back into a low oven at 100C / 200F, or leave them out a few days, turning them so both sides get air.
Can you make salt dough ornaments without an oven?
Yes. Air drying takes one to seven days depending on thickness and how damp your house is, and it removes the puffing problem entirely because the dough never reaches boiling point. Turn them daily. The version I would suggest is a hybrid: air dry one day, then finish at 100C / 200F for a couple of hours.
Is salt dough safe for kids?
Handling it is fine with supervision. Eating it is not. Around four grams of dough carries enough salt to concern a 10 kg child, and separately, most flour is raw and the CDC advises against children eating or playing with dough made from it. Supervise, allow no tasting, and wash hands and surfaces afterwards.
Can dogs eat salt dough ornaments?
No, and this is the serious one. A veterinary review of 14 dogs found symptoms starting around 1.9 grams of dough per kilogram of body weight, which is under 10 grams for a 5 kg dog. Hang them high, keep dough off the floor, and call your vet rather than waiting if your dog eats one. Old ornaments are as salty as new ones.
How do you stop salt dough ornaments from cracking?
Keep the water in the dough to a minimum, roll to a consistent 5 mm rather than thinner, dry slowly at 100C / 200F, and let them cool gradually. I will be straight with you: this is the failure I found the weakest evidence for. The advice fits the rest of the method, but nobody appears to have tested it properly.
How to seal salt dough ornaments?
Only after they are completely dry, which takes days rather than hours. Sealing a damp ornament traps moisture inside and it will go soft. There is no tested winner among sealants. Spray acrylic has better first-hand support than brush-on varnish, which in one documented case pulled the salt out of a whole batch and dried cloudy and cracked. Test on a spare piece.
How long do salt dough ornaments last?
Longer than you would expect if you keep them dry, and I am not giving you a number of years, because every figure you will read online is somebody's recollection rather than evidence. What is documented is the cause of failure: moisture moving in and out of the piece over time. Store them wrapped, somewhere dry and temperature-stable, and they keep.
Can you use self-raising flour for salt dough?
No. Self-raising flour contains a raising agent and it will puff the dough as it dries even if your oven temperature is correct. Use plain all-purpose flour. This is the cause worth checking first if your salt dough ornaments puffed at a low setting, and it catches people who have made them successfully for years and then bought the wrong bag.
