Preheat oven to 350 F. Lightly spray a 12 count muffin tin with cooking spray.
In a large bowl, combine flour, baking soda, Italian seasoning, and salt. Add milk and egg and stir until well combined. Add mozzarella, parmesan and pepperonis. Stir to combine.
Ladle the batter evenly into the prepared muffin tin. Bake until the puffs are golden, 18-20 minutes.
Serve hot with the dipping sauce
