01 - Preheat oven to 350°F. Line a standard 12-cup muffin tin with paper liners or coat generously with nonstick spray.
02 - In a large mixing bowl, whisk together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt until evenly distributed.
03 - In a separate large bowl, beat the eggs, vegetable oil, granulated sugar, brown sugar, and vanilla extract until smooth and well blended.
04 - Fold the grated, well-drained zucchini into the wet ingredient mixture until evenly distributed.
05 - Pour the dry ingredients into the wet mixture and stir gently with a spatula until just combined. Do not overmix.
06 - Gently fold the chopped strawberries and chocolate chips into the batter.
07 - Divide the batter evenly among the prepared muffin cups, filling each approximately three-quarters full.
08 - Bake for 22 to 25 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs attached.
09 - Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
