Part 3/6:
Cocoa Powder: 10 grams of dark cocoa to give that rich chocolate flavor.
Baking Powder and Vanilla Sugar: Enhances the taste and texture of the biscuit.
Eggs: We will use four egg whites to create that fluffy texture in the batter.
Protein Fillings: A combination of whey protein and casein is recommended for the filling, providing great texture and satiety.
Step-by-Step Preparation
Prepare the Base: Start by mixing your sweetener, starch or flour, cocoa powder, baking powder, and vanilla sugar in a bowl.
Add Eggs: Separate the egg yolks from whites. Add the yolks to the dry ingredients and mix to form a rich chocolate batter. Then whip the egg whites until they form stiff peaks, which will be folded gently into the batter.
