Gluten-Free Chocolate Zucchini Bread
A naturally moist chocolate zucchini bread crafted entirely without wheat, making it ideal for gluten-free diets without sacrificing richness. Finely grated zucchini keeps the crumb tender while cocoa powder, cinnamon, and nutmeg create warm, deep chocolate flavor with subtle spice notes. The combination delivers a fudgy texture with just enough structure to slice cleanly. This recipe works for home bakers seeking accessible gluten-free baking, particularly those with zucchini to use up. Serve it warm with butter or plain as an afternoon snack, breakfast item, or casual dessert. The structure relies on approved 1:1 gluten-free flour blends, which perform predictably here without gums or complex substitutions that many gluten-free recipes demand.

Instructions
- 1
Preheat oven to 350 degrees Fahrenheit. Grease a loaf pan with coconut oil or parchment paper.
- 2
Grate zucchini on smallest holes of a box grater. Wrap in a towel and squeeze hard to remove excess liquid. Set aside.
- 3
Whisk together gluten-free flour, cocoa powder, brown sugar, granulated sugar, baking powder, baking soda, salt, cinnamon, and nutmeg in a medium bowl. Set aside.
- 4
In a separate bowl, whisk eggs, then add melted and cooled coconut oil or vegetable oil. Add vanilla and whisk to combine.
- 5
Pour wet ingredients into dry ingredients. Stir with a large spoon until combined.
- 6
Stir in grated zucchini and chocolate chips. Let batter sit 15 minutes at room temperature.
- 7
Pour into prepared loaf pan. Bake 50-60 minutes until a toothpick inserted in center comes out clean.
- 8
Cool in pan 10-15 minutes, then turn out onto a wire rack to cool completely.
Tips
Squeezing zucchini thoroughly removes water that would otherwise create a dense, soggy crumb. Use a clean kitchen towel and press hard; this step is critical for texture.
Let batter rest 15 minutes after mixing. This allows gluten-free flour to fully hydrate and develop structure, resulting in a sturdier crumb that slices cleanly rather than crumbling.
Cool the oil before adding to eggs. Hot oil can cook the eggs, creating scrambled bits rather than a smooth, cohesive batter.
Good to Know
Keep wrapped or in an airtight container at room temperature up to 3 days. Refrigerate up to 5 days. Freeze wrapped loaf or slices up to 3 months.
Prepare and refrigerate batter up to 4 hours before baking. Bake and cool completely before storing.
Serve at room temperature or warm with softened butter, cream cheese, or alongside coffee or tea.
Common Mistakes
Skip or skim squeezing zucchini to avoid soggy, dense crumb from excess moisture.
Omit the 15-minute resting period to avoid crumbly texture; gluten-free flour needs time to hydrate.
Use hot oil to avoid cooking eggs before full mixing, which breaks batter emulsion.

FAQ
Can I use regular all-purpose wheat flour instead of gluten-free flour?
Yes, substitute 1:1 for gluten-free flour. Reduce baking soda to 0.25 teaspoon and baking powder to 0.25 teaspoon, as wheat flour develops gluten and leavening may over-rise. Omit the resting period; wheat flour hydrates faster. Results will be lighter and airier.
How long does this chocolate zucchini bread keep and can I freeze it?
Wrapped or airtight, it keeps 3 days at room temperature, 5 days refrigerated. Freeze the whole loaf or individual slices up to 3 months wrapped in plastic wrap and foil. Thaw at room temperature before serving.
What if I don't have coconut oil?
Use any neutral vegetable oil, canola oil, or melted butter in equal amount. Avoid strong-flavored oils like olive oil. Melted butter adds richness but may slightly alter the crumb texture due to water content.
