01 - In a large microwave-safe mug (at least 12 ounces), combine flour, baking powder, baking soda, and salt using a spoon or small whisk.
02 - Add milk and olive oil to the mug and stir until a smooth batter forms.
03 - Evenly spread pizza sauce over the surface of the batter.
04 - Sprinkle shredded mozzarella cheese over the sauce, then add any desired toppings such as pepperoni, bell pepper, and black olives.
05 - Scatter dried Italian herbs over the top for added flavor.
06 - Microwave on high for 1 minute 30 seconds to 2 minutes, until the cheese is bubbling and the base has set. Cooking time may vary depending on microwave power.
07 - Allow the pizza to cool for 1 to 2 minutes before serving directly from the mug.
