Making the Muffins

1. In a large mixing bowl, whisk together the flour, baking powder, Italian seasoning, and salt.
2. Create a well in the middle of the dry ingredients.
3. In a separate bowl, whisk together the oil, milk, and eggs.
4. Pour the wet mixture into the well in the dry ingredients.
5. Stir everything gently until just combined and the dry spots disappear. Do not overmix.
6. Stir in the shredded mozzarella cheese, diced red pepper, and diced pepperoni.
7. Spoon the batter evenly into 12 muffin cups lined with paper liners.

Adding Toppings and Baking

1. Sprinkle the remaining shredded mozzarella cheese over the top of each muffin.
2. Add a few smaller pieces of pepperoni and one cherry tomato half on top of the cheese layer on each muffin. Place the tomato half with the cut side facing up.
3. Bake the muffins in a preheated 375°F (190°C) oven for about 25 minutes.
4. They are done when the tops look firm to the touch and are lightly golden brown.
5. Let the muffins cool slightly in the pan before moving them to a wire rack.
