Method
Prep and preheat
- Preheat the oven to 350°F and grease a 9x5 loaf pan.
- Whisk all-purpose flour, unsweetened cocoa powder, baking soda, and salt together until evenly combined.
Mix wet ingredients
- Beat granulated sugar, eggs, vegetable oil, Greek yogurt, vanilla extract, and strong brewed coffee (if using) until smooth.
- Stir in the grated zucchini that has been squeezed dry.
Assemble batter
- Fold the dry ingredients into the wet ingredients just until combined.
- Fold in the chocolate chips until evenly distributed.
Bake and cool
- Pour the batter into the greased loaf pan.
- Bake for 55–65 minutes at 350°F until a toothpick comes out with moist crumbs.
- Cool in the pan for 15 minutes before slicing to help the loaf set.
Notes
For the most moist crumb, squeeze the grated zucchini very dry before mixing so it doesn’t make the batter watery. Store leftovers in the refrigerator for up to 4 days. Freezing: yes, wrap slices and freeze up to 2 months. Dietary swap: for a lighter option, use low-fat Greek yogurt, noting the loaf may be slightly less rich.
