We make the cakes in turn as follows (while one cake is baking, prepare the following one, according to the instructions below):
- Beat 2 egg whites until stiff. Add at least 2 tablespoons of sugar, mix until completely melted. Then add the 50g ground walnuts and 0.5 tablespoon of flour mixture. Stir carefully with a spatula to incorporate.
- Turn this mixture out onto the parchment and spread it out with a spoon, inside the drawn circle. It's not a big deal if the edges won't come out perfectly :)
