Roll out the dough and use a small bowl or cup to cut out eight circles of the same size.
Spoon some tomato sauce onto four of the dough circles before placing three slices of pepperoni, another helping of tomato sauce, and some mozzarella on top of them. Then brush some egg wash along the edge of the dough circles which should be free of sauce.
Cut small four small holes into the remaining dough circles using a straw — you want them to look like a button. These are then placed on top of the prepared pizza circles and gently pressed down at the edges using a glass.
Brush the pizza button with egg wash and place them in the oven for 20 minutes at 375 F.
