01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or grease each cup 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 thoroughly. Add the vegetable oil, Greek yogurt, vanilla extract, granulated sugar, and brown sugar. Whisk until the mixture is smooth and well blended.
04 - Gently pour the wet mixture into the dry ingredients. Fold together using a spatula until just combined. Be careful not to overmix, as this can make the muffins tough.
05 - Gently 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 one 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.
