Let the apple puree cool. Once the paste has cooled, cut our dough dumplings in half and stretch them out. By implication, one part will be the bottom of the cookie, on which we smooth the filling, then we put the other portion of dough on it. Prick the top and bake in a preheated oven at 200C° degrees for 20-30 minutes, depending on the oven and the length of preheating.
