How to Make It
Preheat oven to 375°. Whisk together flour, baking powder, and garlic powder in a large bowl. Whisk in milk and egg. Stir in mozzarella cheese, sausage, and pepperoni. Let batter stand 10 minutes, and stir until blended. Coat cups of a 24-cup miniature muffin pan well with cooking spray. Spoon batter into muffin cups. Bake 15 to 18 minutes or until puffed and golden. Serve with warm pizza sauce.
