Greek koulourakia cookies ammonias
Greek koulourakia cookies ammonias are the classic Greek butter cookies leavened with baker’s ammonia (ammonium bicarbonate), which gives a crackly, crisp exterior and tender crumb. In this guide we give a tested recipe, explain the science, sourcing, swaps and troubleshooting.
What are koulourakia and why use baker’s ammonia?
Koulourakia are traditional Greek butter cookies commonly made for Easter and celebrations, shaped into braids, rings or twists and glazed with egg and sesame. Baker’s ammonia or ammonium bicarbonate is the old-school leavener used in many recipes because it produces a uniquely crisp, crackly surface and a light, dry crumb that modern leaveners struggle to match.
Unlike baking powder, baker’s ammonia decomposes into carbon dioxide, water and ammonia gas when heated, and those gases escape quickly from low-moisture doughs. That quick gas release makes thin, shaped cookies puff and then set with a pleasing crispness, which is why many Greek home bakers still prefer it.
Ingredients what to use and why
This recipe is built on simple pantry ingredients. Use room-temperature butter and eggs for even creaming and a predictable dough, and measure flour by weight for consistent results. We recommend 175-1806C (3506F) for even browning and ammonia dissipation.
For baker’s ammonia use a measured, conservative amount. Too much can cause a faint ammonia odor during baking; too little will under-leaven and make the cookies dense. If you need a quick reference, the recipe below uses 1.5 teaspoons (about 4.5 g) for 360 g flour, which is a tested compromise for a mid-size batch.

Step-by-step recipe
Read the full recipe card below for exact weights and the printable method. This section explains technique: preheat, creaming, shaping and finishing. Follow the cues and weigh dough portions when you first try the shapes.
Prep before you start: bring butter and eggs to room temperature, preheat the oven to 175-1806C (3506F), and line baking sheets with parchment. Place the rack in the middle of the oven so the cookies brown evenly.
- Portion size: aim for 24 cookies, about 30-35 g of dough each for medium cookies.
Baking: temperatures, times & tips
Bake at 175-1806C (3506F). Small cookies need 10-12 minutes, medium cookies 12-15 minutes, and large ones 15-20 minutes. Look for golden edges and a light crackling on top; the center should be set but not deep brown.
If you smell ammonia while baking it usually means the gas did not fully dissipate before the cookies left the oven or the dough was too moist. To avoid that, use the recommended oven temp, keep cookies thin, and avoid using baker’s ammonia in very moist or thick cakes where ammonia cannot escape.
Troubleshooting & quick fixes
Common problems with koulourakia often trace back to leavener amounts, oven temp or dough hydration. If cookies come out flat, check oven temp accuracy, reduce liquid slightly, and confirm your baker’s ammonia measurement. If they smell, bake a little longer and ventilate the kitchen.
Here are fast fixes for specific issues:
- Ammonia smell: Bake a bit longer at the same temp, move cookies to a cooler rack, and vent the oven; the smell usually dissipates as ammonia escapes.
- Flat cookies: Chill shaped dough briefly, ensure flour is measured by weight, and check the oven is not too hot at the surface causing early spread.
- Dense interior: Do not overmix after adding flour and confirm you measured the leavener correctly by weight.
Where to buy baker’s ammonia & safety notes
You can find baker’s ammonia under names like “baker’s ammonia” or “ammonium bicarbonate” in specialty baking shops and online. Look for small food-grade packages from European baking suppliers. In the US it is sometimes sold by importers or in food ingredient shops.
Store it in a cool, dry place in an airtight container and keep it away from moisture. It is safe for use in dry baked goods because the ammonia gas vaporizes during baking. Do not use it in moist cakes or thick batters where the gas cannot escape, as that can leave an off odor.
Make-ahead, freezing & storing
You can shape koulourakia and freeze the unbaked shapes on a tray, then transfer to a sealed bag for up to 2 months. Bake from frozen, adding 1-2 minutes to the bake time. Baked cookies keep crisp for about a week in an airtight container at room temperature, and you can re-crisp them at 3006F (1506C) for 5-7 minutes.
We often freeze dough portions. When we pull them out I let them rest briefly at room temperature so the egg wash adheres, then bake as usual. That trick saved a batch last Easter when I ran out of time.
Final tips from Greek home bakers
- Use fresh eggs and room-temperature butter for even texture.
- Brush with egg wash and sprinkle sesame seeds cold so they stick before baking.
- Weigh your leavener where possible and start with the lower amount if testing baker’s ammonia for the first time.

What is baking ammonia and how does it work?
Baking ammonia, also called baker’s ammonia or ammonium bicarbonate, is a dry leavener that decomposes when heated into carbon dioxide, water vapor and ammonia gas. The gases escape quickly from low-moisture doughs which creates lift and a crisp, crackly surface in cookies.
Why do traditional koulourakia recipes use baking ammonia instead of modern leavening agents?
Traditional recipes use baking ammonia because it produces a uniquely crisp exterior and light crumb that baking powder cannot fully replicate. For shaped, thin cookies the quick gas release sets the structure before the dough fully expands, giving the characteristic texture.
Can I substitute baking powder for baking ammonia in koulourakia?
Yes you can substitute baking powder if you cannot source baker’s ammonia, but expect a softer, less crackly cookie. Use about a 1:1 swap by volume as a starting point, test a small batch and adjust since texture and spread will differ.
What does baking ammonia smell like and will it affect the taste of the cookies?
During baking ammonia releases a sharp smell as the gas evaporates, but in properly baked dry cookies the odor dissipates and does not affect taste. If smell lingers, the dough was probably too moist or the cookies left the oven too early; bake a touch longer and ventilate the kitchen.
Where can I find baking ammonia for baking koulourakia?
Baker’s ammonia is sold as ammonium bicarbonate by specialty baking suppliers and some online stores, particularly those that cater to European baking. Buy small food-grade packets, store them sealed and dry, and search sites with terms like ‘baker’s ammonia’ or ‘ammonium bicarbonate’.
What is the difference in texture and crispness between koulourakia made with ammonia versus baking powder?
Koulourakia made with baker’s ammonia tend to have a thinner, crackly shell and drier, more fragile crumb, while baking powder gives a slightly softer, cakier result. For the classic crisp bite choose ammonia for low-moisture, shaped cookies and baking powder for a gentler lift.
