• 3 tablespoons olive oil
• 1 medium onion, chopped
• 235 grams (8 1/3 ounces/1 2/3 cups) all-purpose flour
• 2 tablespoons sugar
• 1 tablespoon baking powder
• 1/2 teaspoon salt, optional
• 2 large eggs, room temperature and lightly whisked
• 227 grams (8 ounces by weight) jarred or homemade pizza sauce
• 1/4 cup mini pepperoni or chopped pepperoni

1. Heat your oven to 400 degrees F and line a 12-cavity muffin tin with muffin liners.
2. Heat the olive oil in a small skillet over medium heat. Add the chopped onions and sauté for about 5 minutes, until softened.
3. Pour the mixture into a large bowl and let cool for five minutes.
4. In a small bowl, whisk together the flour, sugar, and baking powder (and optional salt).
5. Add the eggs, pizza sauce, and pepperoni, and stir. Stir in the cheeses.
6. Fold in the flour mixture until fully combined. The batter will be thick.
7. Scoop the batter into the prepared muffin tin.
8. Bake the muffins for 23 minutes, until lightly browned. Cool in the pan for 5 minutes and then turn them out and let cool for at least 5 minutes more on a wire rack.
