Preheat oven to 400 degrees F and spray your cake pop pan on both sides. Spread pizza crust on a work surface. Using a 3-inch round cutter, cut 12 circles of dough. Cut mozzarella sticks into 1-inch pieces. Place one or two pepperoni slices on each circle of dough and add mozzarella pieces on top. Pinch the dough closed around the cheese and pepperoni. Place the dough balls in the bottom half of the cake pop pan. Attach the top of the pan and secure shut. Bake for 15 minutes. Allow pan to cool for 5 minutes before opening. If some of the pizza balls have ridges in the center, trim them off with a pair of scissors. Using a black/ blue food coloring pen, draw basketball lines on the pizza balls. Add orange food coloring to 1 tablespoon of butter and mix well. Add more food coloring to achieve desired color. Brush the tinted butter on the pizza balls, wiping off any excess with a paper towel.
