Ingredients

Dry Ingredients
- 2 cups gluten-free all-purpose flour blend (with xanthan gum)
- ½ cup unsweetened cocoa powder
- 1½ teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 teaspoon espresso powder (optional but recommended)
Wet Ingredients
- 2 large eggs
- ½ cup vegetable oil or avocado oil
- ½ cup plain Greek yogurt or sour cream
- ¾ cup granulated sugar
- ¼ cup light brown sugar
- 2 teaspoons vanilla extract
Add-Ins
- 2 cups finely shredded zucchini (lightly squeezed)
- ¾ cup semi-sweet chocolate chips
- 2 tablespoons mini chocolate chips for topping (optional)
Step-by-Step Instructions
1. Prepare the Pan
Preheat your oven to 350°F (175°C). Grease and line an 8-inch square baking pan or a 9-inch round cake pan with parchment paper.
2. Mix the Dry Ingredients
In a large bowl, whisk together the gluten-free flour, cocoa powder, baking powder, baking soda, salt, and espresso powder until evenly combined.
3. Combine the Wet Ingredients
In another bowl, whisk the eggs, oil, yogurt, granulated sugar, brown sugar, and vanilla until smooth.
4. Add the Zucchini
Fold the shredded zucchini into the wet mixture. The batter will become slightly thicker as the zucchini blends in.
5. Make the Batter
Pour the wet ingredients into the dry ingredients and stir gently until no dry flour remains. Fold in the chocolate chips without overmixing.
6. Bake
Spread the batter evenly into the prepared pan. Sprinkle extra mini chocolate chips over the top if desired.
Bake for 38–45 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
7. Cool
Allow the cake to cool in the pan for about 15 minutes before transferring it to a wire rack. Cooling completely helps the texture set beautifully.
8. Serve
Dust with powdered sugar, drizzle with chocolate ganache, or enjoy it just as it is.

Health Benefits
While this cake is definitely a dessert, the shredded zucchini adds moisture along with a small boost of fiber, vitamins, and minerals. Using Greek yogurt contributes a little extra protein and helps create a tender crumb without relying entirely on oil.
Choosing a quality gluten-free flour blend also makes this recipe a wonderful option for those avoiding gluten while still enjoying a classic homemade chocolate cake.
Common Mistakes
- Over-squeezing the zucchini, which can make the cake dry.
- Using coarse zucchini shreds that don’t blend well into the batter.
- Overmixing the batter after adding the flour.
- Removing the cake from the oven too early.
- Forgetting to use a gluten-free flour blend that already contains xanthan gum.
Expert Tips
- Finely grate the zucchini so it disappears into the cake.
- Room-temperature eggs help create a smoother batter.
- Espresso powder enhances the chocolate flavor without making the cake taste like coffee.
- Let the cake cool completely before frosting.
- Store leftovers in an airtight container for up to four days, or freeze slices for up to three months.

This cake is especially wonderful during late summer when zucchini is plentiful, but it’s equally cozy throughout the year whenever you’re craving a rich chocolate dessert. It’s perfect for birthdays, weekend baking, potlucks, or a peaceful evening treat shared with family.
Frequently Asked Questions

Absolutely. Wrap individual slices well and freeze for up to three months. Thaw at room temperature before serving.
Which gluten-free flour works best?
A quality 1-to-1 gluten-free baking flour that contains xanthan gum provides the most consistent texture and rise.
