01 - Preheat oven to 350°F. Line a 12-cup muffin pan with paper liners or lightly grease each cup.
02 - In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt until evenly distributed.
03 - In a separate bowl, whisk the eggs, vegetable oil, granulated sugar, brown sugar, and vanilla extract until smooth and well blended.
04 - Pour the wet mixture into the dry ingredients and stir until just combined. Be careful not to overmix.
05 - Gently fold in the grated zucchini, chopped strawberries, and chocolate chips until evenly distributed throughout the batter.
06 - Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full. Sprinkle additional chocolate chips on top if desired.
07 - Bake for 22 to 25 minutes, or until a toothpick inserted into the center of a muffin comes out with a few moist crumbs.
08 - Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
