CHOCOLATE ZUCCHINI BREAD
Yes, it’s zucchini again, but hold off on pumpkin for a bit — this is summer in loaf form. This double-chocolate bread contains two cups of shredded, well-drained zucchini and a cup of chocolate chips, giving it a brownie-like flavor and texture. It’s likely to become your go-to zucchini bake this season.
How to make Chocolate Zucchini Bread?
- Grate the zucchini and squeeze out as much moisture as possible.
- Whisk together the dry ingredients (flour, cocoa, baking powder, baking soda, salt, and sugar).
- Toss the shredded zucchini into the dry mix to coat, then stir in the chocolate chips.
- In a separate bowl or large measuring cup whisk together the wet ingredients (buttermilk, oil, egg, and vanilla).
- Add the wet ingredients to the dry and gently fold until just combined — do not overmix.
- Pour the batter into a prepared loaf pan and tap it on the counter to remove air bubbles.
- Bake until a toothpick inserted in several spots comes out clean.
- Allow the loaf to cool completely before slicing.

Baking with Zucchini
When baking with zucchini it’s essential to remove excess moisture. If shredded zucchini remains wet, it will release water during baking and affect texture. The easiest method is to pile the shredded zucchini onto two stacked paper towels (or cheesecloth), fold it up and squeeze firmly over the sink until most liquid is expelled.

How to make Healthy Chocolate Zucchini Bread?
To lighten the loaf, swap all-purpose flour for whole wheat, use coconut or brown sugar, replace the egg with applesauce, and use almond milk combined with an acid to make a dairy-free buttermilk substitute.
Tips for the best zucchini bread:
- Zucchini: Always squeeze out as much water as possible from shredded zucchini.
- Cocoa: Sift cocoa powder into the dry ingredients to break up any clumps.
- Don’t overmix: Combine ingredients gently with a spatula or wooden spoon for a tender crumb — avoid using a mixer.
