01 - Preheat the 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 the mixture is smooth and well blended.
04 - Gently fold the grated, well-drained zucchini into the wet mixture until evenly distributed throughout.
05 - Pour the dry ingredients into the wet mixture and stir gently with a spatula until just combined. Be careful not to overmix, as this will make the muffins tough.
06 - Gently fold the chopped strawberries and chocolate chips into the batter using a spatula, distributing them evenly with minimal stirring.
07 - Divide the batter evenly among the prepared muffin cups, filling each one approximately three-quarters full.
08 - Bake on the center rack for 22 to 25 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with just a few moist crumbs attached.
09 - Allow the muffins to cool in the pan for 5 minutes, then carefully transfer them to a wire cooling rack to cool completely before serving.
