Step 1

Preheat oven to 350°F. Generously grease 15 muffin cups.

Step 2

In a large bowl, whisk together flour, baking powder, dill, salt, baking soda, and garlic powder. Add zucchini, cheddar, and Parmesan; toss to coat. Stir in eggs, buttermilk, and melted butter, and mix until just combined.

Step 3

Divide batter between prepared muffin cups and bake for 16 to 18 minutes, or until toothpick inserted in center comes out clean. Cool in pan for 5 minutes before running a thin spatula or butter knife around the edge of each muffin and popping it out of the pan and onto a cooling rack. Serve warm or at room temperature.
