Step 1

Preheat oven to 375 degrees F. Spray a muffin tin with nonstick spray or line with muffin liners. Set aside.

Step 2

In a large bowl whisk together flour, cocoa powder, sugars, baking powder, baking soda, and salt.

Step 3

Add the egg, melted butter, and vanilla extract. Add skim milk and stir until combined. Fold in shredded zucchini and chocolate chips (batter will be thick).

Step 4

Divide batter evenly between the prepared muffin cups and place in the oven. Bake for 20-25 minutes or until a toothpick inserted in the middle comes out clean. Remove from the oven and let muffins cool in muffin pan until they’re safe to handle, about 10 minutes. Transfer to a wire rack to cool completely.
