Preheat the oven to 425°F and butter the cups of a muffin pan.

Divide the pizza dough into 12 portions. Roll each portion into a ball and place one ball in each muffin cup. Cover the pan with plastic wrap and let the dough rise a bit.

In a small bowl, combine the shredded mozzarella and Muenster cheeses and mix well.

Butter a shot glass. Press the buttered shot glass into the center of each risen dough ball. The dough will spread up the sides of the cup, forming a cavity.

Add 2 small spoonfuls of pizza sauce to the center of each piece of dough followed by a few slices of pepperoni. Top with cheese blend and a sprinkle of Italian seasoning.

Bake for about 15 minutes, until the tops are golden brown.
