01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or grease lightly with nonstick spray.
02 - In a large mixing bowl, whisk together the all-purpose flour, cocoa powder, baking soda, baking powder, and salt until evenly distributed.
03 - In a separate medium bowl, beat the eggs. Add the vegetable oil, Greek yogurt, vanilla extract, granulated sugar, and brown sugar. Whisk until smooth and well blended.
04 - Gently fold the wet mixture into the dry ingredients using a spatula, stirring until just combined. Avoid overmixing to keep the muffins tender.
05 - Fold the grated zucchini, diced strawberries, and chocolate chips into the batter until evenly distributed.
06 - Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.
07 - 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.
08 - Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely before serving.
