Keto Cinnamon Cookies – Soft, Cozy, and Low-Carb

You don’t need special skills or fancy ingredients—just a few pantry staples and 20 minutes. Bake a batch once and you’ll find yourself coming back to them again and again.
Ingredients
Method
- Preheat and prep: Heat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
- Mix dry ingredients: In a large bowl, whisk together almond flour, coconut flour, baking powder, salt, and 2 teaspoons of cinnamon until evenly combined.
- Cream butter and sweetener: In another bowl, beat the softened butter with the granulated sweetener for 1–2 minutes until light and slightly fluffy. Add the egg, egg yolk, and vanilla. Mix until smooth.
- Combine: Add the dry mixture to the wet mixture. Stir with a spatula until a soft dough forms. It should be thick but scoopable. If it seems too soft, let it rest 3–5 minutes so the coconut flour can absorb moisture.
- Make the coating (optional): In a small dish, combine 1–2 tablespoons sweetener with 1 teaspoon cinnamon. This gives a snickerdoodle-style crust.
- Portion the dough: Use a tablespoon or small cookie scoop to form 18–20 balls. Roll each ball lightly in the cinnamon-sweetener mixture if using.
- Flatten: Place on the lined baking sheet with a little space between them. Gently press each ball to about 1/2 inch thick. Keto cookies don’t spread much on their own.
- Bake: Bake for 8–10 minutes, until the edges look set and the bottoms are lightly golden. The centers should still look a bit soft.
- Cool: Let the cookies cool on the baking sheet for 10 minutes to firm up, then transfer to a rack. They’ll set as they cool and become perfectly chewy.
- Enjoy: Sprinkle a touch more cinnamon if you like, and serve warm or at room temperature.

- 1/2 teaspoon fine sea salt
- 2 teaspoons ground cinnamon (plus 1 teaspoon for coating, optional)
- 1/2 cup (100 g) granulated erythritol or allulose blend (plus 1–2 tablespoons for coating, optional)
- 6 tablespoons (85 g) unsalted butter, softened (or refined coconut oil for dairy-free)

- 1 teaspoon vanilla extract
- Optional: 1/4 teaspoon ground nutmeg or cardamom for extra warmth
Step-by-Step Instructions

How to Store
- Room temperature: Store in an airtight container for up to 4 days. Add a small piece of parchment between layers to prevent sticking.
- Refrigerator: Keeps well for up to 1 week.
This can make them a bit firmer and chewier, which many people love.
- Freezer: Freeze baked cookies for up to 2 months. Thaw at room temperature or warm for 5 minutes in a 300°F (150°C) oven.
- Freeze the dough: Scoop and flatten the dough, then freeze on a tray. Move to a freezer bag once solid.
Bake from frozen, adding 1–2 minutes to the bake time.
Why This is Good for You
- Low in net carbs: Almond and coconut flours dramatically reduce carbs compared to wheat flour, making these cookies keto-friendly.
- Healthy fats and fiber: Almond flour and butter provide satiating fats, while coconut flour adds fiber that supports digestion.
- No refined sugar: Using erythritol or allulose keeps blood sugar impact low, helping you stay on track with your goals.
- Cinnamon benefits: Cinnamon adds flavor without carbs and may support healthy blood sugar levels.
Pitfalls to Watch Out For
- Overbaking: Keto cookies can go from perfect to dry fast. Pull them when the edges are set but centers are soft.
- Skipping the rest: If your dough looks sticky, a short rest lets the coconut flour hydrate. Don’t skip it.
- Using the wrong sweetener: Pure stevia drops won’t provide structure.
Stick to a granulated keto sweetener like erythritol or an allulose blend.
- Measuring flours loosely: Almond flour packs easily. For best results, use a scale or gently spoon and level your cups.
- Too much cinnamon in the dough: More isn’t always better. Too much can taste bitter.
Stick to the amounts listed and add extra as a coating.
Recipe Variations
- Cinnamon Roll Swirl: Make a quick paste with 1 tablespoon melted butter, 1 tablespoon sweetener, and 1 teaspoon cinnamon. Swirl a tiny bit into the top of each cookie before baking.
- Pecan Crunch: Fold in 1/3 cup chopped toasted pecans for texture and a nutty note.
- Dairy-Free: Use refined coconut oil instead of butter and add a pinch more salt. Refined oil keeps the flavor neutral.
- Maple-Cinnamon: Add 1/2 teaspoon maple extract to the dough for a cozy, pancake-house vibe (still keto if the extract is sugar-free).
- Chai Spice: Replace 1 teaspoon cinnamon with a chai blend (cinnamon, ginger, cardamom, clove) for a café-style twist.
- Extra Chewy: Replace 2 tablespoons of the erythritol with allulose if you prefer a softer, chewier cookie.
FAQ
Can I use coconut flour instead of almond flour?
Coconut flour behaves very differently and can’t be swapped 1:1.
It absorbs much more liquid and would make the cookies dry and crumbly. If you must go nut-free, look for a recipe developed specifically for coconut flour.
What sweetener works best?
A granulated erythritol or an allulose-erythritol blend works well. Allulose browns more and gives a chewier texture, while erythritol stays crisper but can cool on the tongue. You can also use monk fruit blends that contain erythritol or allulose.
Why did my cookies fall apart?
They probably needed more time to cool, or the dough was too dry.
Let the cookies rest on the baking sheet before moving them, and make sure you measured the flours accurately. If needed, add 1–2 teaspoons of almond milk to the dough next time.
Can I make them egg-free?
You can try a flax egg (1 tablespoon ground flax + 2.5 tablespoons water, rested 5 minutes), but the texture will be more delicate. Chill the dough before baking and handle gently.
How many carbs per cookie?
Exact macros depend on your brands and cookie size, but typically each cookie lands around 2–3 grams net carbs.
Use your nutrition tracker with your specific ingredients for the most accurate numbers.
Do I have to flatten the dough?
Yes. These cookies don’t spread much in the oven. Press them to about 1/2 inch thick so they bake evenly and get the right texture.
Can I add a glaze?
Sure.
Mix powdered erythritol with a splash of heavy cream or almond milk and a pinch of cinnamon. Drizzle lightly once the cookies are fully cool.
