Step‑by‑Step Instructions for Chocolate Zucchini Bread
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (180°C). While it warms up, grab a 20 cm loaf pan and either line it with parchment paper or lightly grease it with butter or cooking spray. This will prevent the Chocolate Zucchini Bread from sticking and ensure easy removal after baking.
Step 2: Mix Milk and Vinegar
In a medium bowl, combine 120 ml of your choice of milk with 1 teaspoon of apple cider vinegar. Whisk the mixture together and let it sit for about 5 minutes. This step helps to create a buttermilk-like quality that will enhance the moisture and fluffiness of your Chocolate Zucchini Bread.
Step 3: Prepare the Zucchini
Grate 90 grams of zucchini using a box grater or food processor for even results. Once grated, wrap it in a clean paper towel or cheesecloth and squeeze out as much excess moisture as possible. This crucial step ensures your bread doesn’t turn out soggy, enhancing its perfect texture.
Step 4: Combine Wet Ingredients
In a large mixing bowl, beat together 1 egg, 100 grams of mashed ripe banana, 60 grams of maple syrup, 20 ml of vegetable oil (or melted butter), and 1 teaspoon of vanilla extract. Use a whisk or electric mixer to blend until the mixture is well combined and creamy, ensuring your Chocolate Zucchini Bread will be moist and flavorful.
Step 5: Incorporate the Zucchini
Gently fold the prepared zucchini into the wet mixture until evenly distributed. This step adds moisture and nutrition without compromising the delicious chocolate flavor. Take a moment to appreciate the vibrant green of the zucchini before moving on to the dry ingredients!
Step 6: Sift Dry Ingredients
In a separate bowl, sift together 150 grams of oat flour, 50 grams of cocoa powder, 1 teaspoon of baking powder, and ⅓ teaspoon of baking soda. Gradually add this dry mixture to the wet ingredients, gently stirring to combine until there are no lumps left. This creates a smooth batter for your Chocolate Zucchini Bread.
Step 7: Mix in Milk
Pour the prepared milk and vinegar mixture into the batter, mixing until everything is thoroughly incorporated. It’s important to maintain a lump-free consistency, as this will help ensure an even texture throughout your Chocolate Zucchini Bread.
Step 8: Fold in Chocolate Chips
Now it’s time to add 3 tablespoons of chocolate chips into the batter, folding them in gently so they are evenly distributed. For an extra chocolatey kick, reserve a few chips to sprinkle on top before baking. This little touch really enhances the appeal of your delicious Chocolate Zucchini Bread.
Step 9: Bake the Bread
Pour the prepared batter into the loaf pan and spread it evenly. Place it in the preheated oven and bake for 30-40 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs. Keep an eye on the bread, as baking times may vary based on your oven.
Step 10: Cool and Serve
Once baked, remove your Chocolate Zucchini Bread from the oven and let it cool in the pan for about 10 minutes. Carefully transfer it to a wire rack to cool completely before slicing. This resting time allows the flavors to develop, resulting in an even more delightful treat when served.

How to Store and Freeze Chocolate Zucchini Bread
Room Temperature: Store in an airtight container for up to 3 days to maintain freshness. Enjoy without the need to refrigerate for a cozy treat!
Fridge: If you prefer a chill, refrigerate in an airtight container for up to 4 days. This helps prolong the flavor and moisture while enhancing the zucchini’s richness.

Reheating: Thaw overnight in the fridge and reheat individual slices in the microwave for 15-20 seconds or in a toaster oven for a few minutes, bringing back that freshly baked flavor!
