Are you team Chocolate Chip Zucchini Bread or Banana Bread? I love both so much, and these recipes are pretty similar because they both have a similar secret ingredient... Mayonnaise! The addition of Mayo makes the bread a soft, moist, and delicious treat. Don't have Mayo on hand? Sub it for sour cream and it works the same! Adding this into the bread makes it the best chocolate chip zucchini bread you'll ever taste.

You won't need any fancy kitchen tools to make this recipe, so let's roll up our sleeves and get to it!
Ingredients for Chocolate Chip Zucchini Bread
- Zucchinis
- Granulated sugar
- Brown sugar
- Egg
- Vanilla
- Salt
- Butter
- All-purpose flour
- Baking soda
- Ground cinnamon
- Mayonnaise
- Semisweet chocolate chips + more for on top of the loaf (optional)

Instructions for Chocolate Chip Zucchini Bread
Preheat and Prepare:
- Preheat your oven to 350 degrees F. Grease a bread pan with shortening or butter and lightly coat it with flour to ensure easy release later on.
Create the Wet Mixture:
- In a large bowl, combine granulated sugar, brown sugar, egg, vanilla, salt, and melted butter. Whisk these ingredients together until they form a smooth and creamy mixture.
Prepare the Dry Ingredients:
- In a separate, smaller bowl, mix the dry ingredients—flour, baking soda, and ground cinnamon. Gradually add this dry mix into the wet ingredients, stirring until a slightly grainy substance forms.
Add Zucchini and Mayo:
- Introduce the star ingredient—grated zucchini—into the bowl and stir until it slightly softens. The mixture will be thick and not quite batter-like at this point. After stirring for 2 minutes, add in the mayo, blending until completely combined and a batter-like consistency is achieved.
Chocolate Chip Magic:
- Gently fold in the semisweet chocolate chips, ensuring they are evenly distributed throughout the batter.

Bake to Perfection:
- Pour the batter into the prepared bread pan and bake in the preheated oven for approximately 50 - 70 minutes (adjust depending on your oven). To test for doneness, insert a toothpick or knife into the center; if it comes out clean, your bread is ready.

Cool and Enjoy:
- Allow the bread to cool in the pan for 10 minutes before transferring it to a wire rack. Once cooled, slice into thick, tempting pieces, and savor the delightful combination of moist zucchini, rich chocolate chips, and the secret ingredient—mayo.

Variations & Substitutions
If you don't have Mayo on hand, you can make this delicious chocolate chip zucchini bread with sour cream and the result is the same. Using Mayo makes it easier to make this recipe gluten and dairy free. I have a family member who can't eat gluten or dairy, and they will typically customize my recipes so they can try them. Feel free to do that for yourself as well!

Chocolate Chip Zucchini Bread
Ingredients
- 2 medium sized zucchinis grated
- ¾ cup granulated sugar
- ¼ cup brown sugar
- 1 egg
- 1 teaspoon vanilla
- Pinch of salt
- ½ cup butter melted
- 1 ½ cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- ¼ cup mayo
- ¾ cup semisweet chocolate chips + more for on top of the loaf optional
Instructions
- Preheat the oven to 350 degrees F. Grease a bread pan with shortening or butter and sprinkle flour around in the pan to coat the edges. Once all edges are coated, set the pan aside.
- In a large bowl, combine the granulated sugar, brown sugar, egg, vanilla, salt, and melted butter. Whisk together until combined.
- In a separate, small bowl, combine the dry ingredients: flour, baking soda and cinnamon. Add into the wet ingredients and mix until a grainy substance has formed.
- Add Zucchini into the bowl and stir until it slightly softens. The mix will be very thick and not quite batter-like yet. Once you have stirred in the zucchini for 2 minutes, add in the mayo.
- Stir the mayo in and mix until completely combined and the mixture has a batter-like substance.
- Fold in the chocolate chips, and sprinkle more on top if you would like. Pour into the greased bread pan and bake for 50 minutes (depending on your oven it could be anywhere from 45 to 70 minutes — my oven’s sweet spot is 50 minutes for this recipe).
- Once the time is up, check the bread with a toothpick or knife and if it comes out clean it’s ready. Let cool in the pan for 10 minutes. Remove, slice and enjoy!
