Homemade Milk Slices

Preheat the oven to 200⁠–⁠205 °C and prepare a baking sheet (30 cm × 40 cm), lining it with baking paper.

Prepare a bowl and a taller container for whipping. Then prepare the eggs and separate the yolks from the whites: Put the yolks into the bowl and the whites into the taller container.

Take a larger bowl and pour in the semi-coarse flour, potato starch, Dutch cocoa, and baking powder. Then add all the egg yolks, 50 ml of milk, and 50 g of powdered sugar to the bowl and whisk everything thoroughly with a whisk.
