1 3/4 cups all-purpose flour
1 1/2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
1/4 cup butter, melted
1 egg, lightly beaten
1 cup milk
1 cup shredded unpeeled zucchini
1 clove garlic, minced
3/4 cup shredded Cheddar cheese
1/4 cup freshly grated Parmesan cheese
4 slices bacon, cooked crisp and crumbled
1. Preheat oven to 350 degrees F (175 degrees C). Line 12 cup muffin cups with paper liners, or spray with cooking spray.
2. Mix the flour, baking powder, baking soda, and salt in a bowl
3. In another bowl, stir together the butter, egg, milk, zucchini, and garlic until well blended. Mix the flour mixture into the milk mixture, about 1/2 cup at a time, stirring between additions, until the flour mixture is incorporated. Fold in the Cheddar cheese, Parmesan cheese, and crumbled bacon, and pour the batter into the prepared muffin cups.
4. Bake in the preheated oven until a toothpick inserted into the center of a muffin comes out clean, 30 to 35 minutes. Serve warm. Refrigerate leftovers.
