Place pizza dough in a bowl, cover, and allow to proof for 1 hour, or until it has doubled in size.
After it has proofed, lay the dough out on a floured surface and roll it into a rectangle. (My rectangle was approximately 15” X 11”). Lightly brush the dough with the pizza sauce, then top with cheese and pepperoni.
Trim and discard the edges of the dough, to make a rectangle with straight lines.
Cut the rectangle into 5 equal strips, approximately 3” wide. Cut the strips into four squares, I found it easiest to run a line down all the strips at once, creating twenty squares total. I found it easiest to then stack five squares on top of each other, making four piles.Lightly spray a 9” x 5” loaf pan with cooking spray. Stack the squares against each other, in the pan, with the cut edges down. The squares will not fill up the pan, so don’t worry if it looks empty! Cover the pan and let it proof for 30 minutes.
Preheat the oven to 350°F
Place the loaf on a baking sheet and let it bake for 15-20 minutes.
Mix the melted butter and crushed garlic together. Remove the pan from the oven, lightly brush the top of the loaf with garlic butter, and allow it to bake for another 15-20 minutes. The top of the loaf should be golden brown.
Remove the loaf from the oven and let it cool before turning it onto a serving plate.
