Method
Prep
- Preheat the oven to 350°F and grease a 9x5-inch loaf pan, leaving no dry spots on the sides.
- Whisk the vegetable oil, sugar, eggs, and vanilla extract in a mixing bowl until smooth and glossy.
Mix the batter
- Stir the all-purpose flour, cocoa powder, baking soda, salt, and cinnamon together in the bowl, then add to the wet mixture.
- Fold in the grated zucchini, squeezed dry, and fold in the chocolate chips until just combined and no dry streaks remain.
Bake
- Pour the batter into the greased loaf pan and top with extra chocolate chips if desired.
- Bake at 350°F for 55 minutes, until a toothpick in the center comes out mostly clean with a few moist crumbs.
- Cool in the pan before slicing so the crumb sets and the chocolate stays gooey rather than runny.
Notes
Squeeze the zucchini well (or blot in paper towels) to avoid a soggy loaf. Store airtight at room temperature up to 2 days or refrigerate up to 5 days; freeze slices up to 2 months. Dietary swap: use coconut oil in place of vegetable oil for a slightly different flavor while keeping the same texture.
