Double Chocolate Zucchini Bread

Rich, moist, and secretly full of vegetables — the garden’s zucchini surplus never looked so good.

Why This Recipe

Zucchini season is relentless. One plant is ambitious. Two plants is a commitment. Three plants is a cry for help. By midsummer you’re leaving bags of zucchini on every doorstep in the neighborhood, and there are still more on the vine. This recipe is one of the best answers to that problem — because nobody ever turns down chocolate bread.

The zucchini is the secret, not the compromise. You don’t squeeze out the moisture like you would for mac and cheese. Here, that moisture is the point — it keeps the bread tender for days, which means less food waste and better texture. The shredded zucchini practically disappears into the batter. You’d never know it was there if you hadn’t made it yourself.

Naturally gluten-free. This recipe was developed gluten-free from the start using Bob’s Red Mill 1-to-1 Baking Flour. No substitutions, no workarounds — it just works.

The Story

By late July the zucchini surplus is real, and when you’re also gluten-free, your options narrow fast. I needed something that used a lot of zucchini, worked without wheat flour, and that people would actually want to eat. When I found this recipe on ChefAlina.com, it checked every box.

My modifications: I use milk chocolate chips instead of dark or semi-sweet — the original recipe is already rich from the cocoa powder, and milk chocolate adds a sweeter, creamier layer that balances the bitterness in a way I really like. I also added a quarter teaspoon of cardamom alongside the cinnamon, a small addition that rounds out the warmth without announcing itself. If you prefer a more intense chocolate flavor, semi-sweet or dark chips work just as well.

And more often than not, this becomes muffins in my kitchen, not bread. Faster bake, easier to freeze individually, no slicing required — if you’re deciding between the two, that’s my honest default.

The 30-minute rest before baking isn’t optional. With gluten-free flour, that rest time lets the flour fully hydrate, and the difference in texture is noticeable. Set a timer and walk away. It’s worth it.

Key Details

Prep Time: 20 minutes | Rest Time: 30 minutes | Cook Time: 55–65 minutes (25 minutes for muffins) | Total Time: 1 hour 50 minutes | Yield: 2 loaves (8x4-inch) or 1 loaf + 12 muffins | Diet: Gluten-Free, can be dairy-free

Sustainability Note: This recipe turns late-summer zucchini abundance into something your family will actually ask for by name. Shred and freeze extra zucchini in measured portions when the garden is going — thaw and use all winter.

The Recipe

Ingredients

Instructions

1. Preheat and prep: Preheat oven to 350°F. Grease two 8x4-inch loaf pans (or one pan plus a 12-cup muffin tin). Line with parchment paper for easy removal.

2. Shred the zucchini: Use a box grater or food processor. Do not squeeze out the moisture — it keeps the bread tender.

3. Mix wet ingredients: In a large bowl, beat together the granulated sugar, brown sugar, and oil. Add eggs, milk, and vanilla and beat until well blended. Stir in the shredded zucchini.

4. Mix dry ingredients: In a separate bowl, whisk together the GF flour, salt, baking soda, baking powder, cocoa powder, cinnamon, and cardamom. Make sure there are no cocoa lumps.

5. Combine: Gradually add the dry mixture to the wet mixture, stirring until just combined. Fold in the chocolate chips.

6. Rest the batter: Set aside for 30 minutes. This step is important — it gives the GF flour time to fully hydrate and improves the final texture significantly.

7. Bake: Pour batter into prepared pans. Bake loaves for 55–65 minutes, until a toothpick inserted in the center comes out clean. Muffins bake for about 25 minutes. If tops brown too quickly, tent loosely with foil for the last 15 minutes.

8. Cool: Cool in pans for 10 minutes, then remove to a wire rack to cool completely.

Notes & Variations

• Don’t squeeze the zucchini: Unlike the mac and cheese, you want that moisture here — it’s what keeps the bread tender for days.
• No need to peel: The skin adds nutrition and is completely undetectable in the finished bread.
• Room temperature ingredients: Helps everything blend smoothly.
• Rest time is non-negotiable: Don’t skip the 30-minute rest. The texture difference is real.
• Chocolate chip choice: I use milk chocolate chips for a sweeter, creamier finish. Semi-sweet or dark chips give a more intense chocolate flavor — either works.
• Cardamom: A quarter teaspoon alongside the cinnamon — my addition. It’s a background note, not a flavor you’d name outright.
• I make this into muffins more than bread. They bake faster, they’re easier to freeze and grab individually, and there’s no slicing involved. If you’re choosing between the two, muffins are genuinely my default.
• Freezer friendly: Wrap individual slices and freeze up to 3 months. Thaw at room temperature or microwave 20–30 seconds.
• Make ahead: Tastes even better the next day as flavors develop.

Variations:

• Extra chocolate: Use 1 1/2 cups chips instead of 1 cup
• Nuts: Add 1/2 cup chopped walnuts or pecans
• Espresso boost: Add 1 tsp instant espresso powder to the dry ingredients — deepens the chocolate flavor
• Muffins: Makes about 24 muffins — bake 20–25 minutes
• Dairy-free: Use almond milk and dairy-free chocolate chips

Gluten-Free Notes:

This recipe was developed gluten-free. The GF flour used is Bob’s Red Mill 1-to-1 Baking Flour. The 30-minute rest is especially important with GF flour — don’t skip it.

Storage & Make-Ahead

• Room temperature: Airtight container for up to 3 days
• Refrigerator: Up to 1 week
• Freezer: Wrap individual slices, freeze up to 3 months
• Freeze shredded zucchini: When the garden is producing faster than you can bake, shred the zucchini and freeze in 1-pound portions. Thaw and use directly — no re-squeezing needed.

The garden doesn’t ask whether you’re ready. By August, you either find ways to love zucchini or you start leaving bags on doorsteps. This is the recipe that made me genuinely look forward to the abundance.
