Step 1Mix the dry ingredients: cacao powder, Erythritol, cream of tartar, baking soda and vanilla powder (or cinnamon).
Note: Cream of tartar and baking soda act as leavening agents. This is how it works: To get 2 teaspoons of gluten-free baking powder, you need 1/2 a teaspoon of baking soda and 1 teaspoon of cream of tartar. Instead of this mixture, you can also use gluten and aluminum free baking powder.
