Preheat oven to 400 degrees Fahrenheit and spray a baking sheet with non-stick cooking spray. Cut the 3 mozzarella cheese sticks into 4 pieces each, 12 pieces total.
Separate the 1 (16-ounce) can refrigerated biscuits and cut them into 12 equal pieces. Place one piece of cheese in the center of each biscuit piece, and pinch the sides around the cheese so it is completely encased.
Place the seam-side down on the prepared baking sheet. Bake for 10 minutes until golden.
Melt the 4 tablespoons butter and stir in 1 teaspoon garlic powder, 1 teaspoon Italian seasoning, and 1 tablespoon parmesan cheese. When the biscuits are out of the oven, brush the butter mixture over each biscuit. Serve warm.
