Chocolate Loverโs Zucchini Bread!
Almost every sunday, my daughter and I bake muffins or cookies together. Itโs our thing. Sheโs my little chocolate lover, always asking for double chocolate chip muffins (with extra chips, of course).
So when I mentioned making my favorite zucchini bread, she paused and said, โCan we make it double chocolate instead?โ How could I say no?
We grabbed the cocoa, poured in a few handfuls of chocolate chips, and ended up with this rich, fudgy loaf that she now calls โZucchini Muffin Bread.โ Weโve made it three times since. Safe to say itโs a new favorite.
Chocolate Zucchini Bread Ingredients
| Ingredient | Why It Works | Swaps or Tips |
|---|---|---|
| Finely grated zucchini (no peeling) | Adds moisture with zero veggie flavor | Yellow squash in a pinch |
| Dutchโprocess cocoa powder | Gives a darker, smoother chocolate flavor | Natural cocoa for a lighter color |
| Dark chocolate chips | Extra bursts of chocolate | Milk or semiโsweet chips |
| Fullโfat Greek yogurt | Protein and tenderness | Sour cream |
| Coconut oil, melted & cooled | Keeps the crumb soft and dairyโfree | Melted butter or avocado oil |
| Oat flour (blended oats) | Adds fiber and a light nutty flavor | Just throw oats in the blender and blend to a flour consistency |
How To Make Chocolate Zucchini Bread
- Prep Grease or line an 8.5โฏรโฏ4.5โinch loaf pan and heat oven toโฏ350โฏยฐF.
- Mix Wet Whisk yogurt, honey, brown sugar, eggs, melted coconut oil, and vanilla.
- Melt Chocolate Warm chips, then stir into wet mix.
- Mix Dry Whisk oat flour, cocoa, baking soda, baking powder, and salt.
- Combine Gently fold dry mix into wet mix, then add zucchini and extra chips.
- Bake Pour batter into pan and bake 45 to 55โฏminutes until a toothpick shows moist crumbs.
- Cool Rest loaf 10โฏminutes, transfer to a rack, cool fully, then slice.
Quick Tip
Unfortunately, you can not use ALL oat flour in this bread. I have tried it and it was not successful. Also if you attempt to use a different flour in this recipe, please note that it may not yield the right texture. Oat flour absorbs much more liquid than regular flour.
Baking Tips
- Grease plus a light flour dust or line it with parchment paper to keep the loaf from sticking.
- Leave the zucchini wet; its juice keeps the crumb tender.
- Flourโdust chocolate chips so they stay suspended in the loaf.
- If the top browns too fast, tent with foil for the last 10โฏminutes.
- Use the right size pan. I use an 8.5 x 4.5-inch bread pan for this recipe; it doesnโt bake up the same in other-sized pans.
How To Know Chocolate Zucchini Bread Is Done
- The loaf pulls away from the sides of the pan.
- A toothpick in the center shows only a few sticky crumbs.
- The top springs back when lightly pressed.
Preventing underbaked zucchini bread: Make sure yourย oven is correctly calibrated; wait for the oven to fully preheat before adding the bread to the oven and position the loaf in the center of the oven.

Equipment
Ingredients
- 1/2 cup honey vanilla Greek yogurt
- 2 tablespoons honey
- 1/2 cup light brown sugar lightly packed
- 1/3 + 3/4 cup dark chocolate chips divided
- 1/3 cup melted coconut oil
- 1-1/2 teaspoons vanilla extract
- 1 large egg
- 1/3 cup oat flour just blend regular oats in a blenderโsee note 1
- 2 tablespoons Dutch process cocoa powder recommended: Hersheyโs Special Dark cocoa powder
- 1 teaspoon baking soda
- 1/4 teaspoon baking powder
- 1/2 teaspoon salt
- 1 cup all-purpose flour or use white-whole wheat
- 3/4 heaping cup lightly packed grated zucchini
- 1 tablespoon cornstarch
Instructionsย
- Preheat oven to 350ยฐF (176ยฐC). Lightly grease and flour an 8-1/2 by 4-1/2 inch pan or line with parchment paper, leaving an overhang for easy removal. Grate zucchini on the small holes of a grater. Measure and set aside.
- In a medium bowl, stir together the Greek yogurt, honey, and brown sugar until smooth.
- In another small microwave-safe bowl, place 1/3 cup (62g) chocolate chips. Melt the coconut oil and measure the oil after being melted. Pour the melted coconut oil over the chocolate chips and stir. Microwave in bursts of 15 seconds, stirring for 20 seconds between each burst until chocolate is fully melted and smooth. Allow to cool to room temperature, then use a spatula to scrape every bit into the Greek yogurt mixture. Stir to combine. Add the egg and vanilla extract and stir until smooth.
- In a separate bowl, stir together the oat flour (see note 1), cocoa powder, baking soda, baking powder, salt, and cornstarch. Add in the flour and the remaining 3/4 cup chocolate chips (118g). Stir the dry ingredients together.
- Add the dry to the wet. Mix in the zucchini. Gently stir until just combined. Overmixing will result in dense bread or a sunken center.
- Use a spatula to scrape every bit of the mixture into the prepared pan and smooth the top into an even layer. Top with a few more chocolate chips if desired. Bake for 45โ55 minutes or until a toothpick when inserted into the center comes out with dry or moist (not wet) crumbs. The bread should also be pulling slightly away from the sides. Be careful to not overbake; it will yield a much drier, less-tasty zucchini bread.
- Remove from the oven and let cool for 10 minutes before inverting it onto a cooling rack to finish cooling. Allow to completely cool before cutting into the breadโotherwise, itโs pretty crumbly! Cut with a sharp, serrated knife. Best enjoyed the same dayโsee โStorageโ notes below.

Recipe Notes
Note 1: I use regular old-fashioned or quick oats and quickly pulse them in a blender or food processor until they resemble flour. Then, measure and add to the bowl (the measurement should be taken after the oats are blended, not before).
Storage:ย Store bread airtight for 1โ2 days at room temp; after 3โ4 days, it may mold due to moisture. Freeze leftovers up to 3 months, wrapped individually. Thaw at room temp for an hour and reheat briefly. Try it with peanut butter for a tasty twist!

I donโt see how much zucchini is in the recipe?
In the recipe card it calls for a heaping 3/4 cup! I hope this helps!
