Pile the dry ingredients on a work surface or put them in a large bowl, cut the butter into pieces, add the eggs and knead everything vigorously. Add cocoa to make a dark dough. Let the dough rest for about 1 hour.
With a pastry syringe or the meat grinder, squirt donuts, chopsticks or S onto the baking sheet (greased or with baking paper).
Bake in the preheated oven at approx. 175 ° C for about 10 minutes, until the baked goods are lightly browned. After cooling, decorate with melted couverture, powdered sugar or icing.
One serving makes about 3 - 4 baking trays for me, I always make at least double the amount. Since the dough hardly runs apart, a few millimeters space on the sheet is enough. The dough can be prepared in no time, but it takes a little more time to process, especially for a nice decoration.
