Lightly flour your work surface and roll and stretch the thawed dough into a rectangle that is about 12 x 10 inches. This doesn’t have to be perfect, so don’t stress about the exact dimensions; as long as it’s close, you’re good to go.

Combine melted butter with the pizza seasoning and garlic powder and mix until combined. 

Use a pastry brush to brush the rolled dough with half of the melted butter mixture. Evenly cover the surface of the dough with pepperoni and then sprinkle on the mozzarella cheese.

Beginning with a long side, roll up dough jelly-roll style. Pinch the ends and place the loaf seam-side down onto the prepared baking sheet. Use a sharp knife to cut 3 small vents in the top of the loaf.

Brush with remaining butter mixture and sprinkle with parmesan cheese. 

Bake in preheated oven for 20-25 minutes or until golden brown. 

Allow to cool for about 10 minutes before slicing with a serrated knife. Serve with pizza sauce or marinara sauce.
