Bake the cake layers

Preheat oven to 400F. Set the rack in the middle.
On a back of a jelly roll or a 12-inch baking sheet, roll out 1/2 of 1 dough ball, until about 12.5 inches in size, by dusting the surface with flour as needed.
Prick with a fork all over, to prevent uneven rising. Bake for 5-7 minutes, until lightly golden in color. Repeat with the rest of the dough, to make 8 layers.
As soon as the cake layer is baked and out of the oven, place an 11-inch plate or lid on top of each cake layer and cut around, collecting the scraps into a separate bowl and being careful to keep the cake layers from cracking.
