Ingredients
Scale
Dry Ingredients
- 2 cups gluten-free flour blend
- 3/4 cup Dutch-processed cocoa powder
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon xanthan gum (omit if your blend contains it)
- 1/2 teaspoon salt
- 1 teaspoon espresso powder
- 1/4 teaspoon ground cinnamon
Wet Ingredients
- 3 cups shredded zucchini (after squeezing excess moisture)
- 1/2 cup vegetable oil
- 1/2 cup unsweetened applesauce
- 3 large eggs, room temperature
- 1 cup granulated sugar
- 1/2 cup packed brown sugar
- 2 teaspoons vanilla extract
- 4 ounces bittersweet chocolate, melted and slightly cooled
- 1/2 cup buttermilk, room temperature
- 1/2 cup mini chocolate chips
Note
- Additional 1-2 tablespoons reserved zucchini liquid (optional, if batter is too thick)
Instructions
- Prepare Zucchini Properly: Shred the zucchini using the standard holes on a box grater. Place the shredded zucchini in a clean kitchen towel and squeeze firmly to remove excess moisture, reserving about 2 tablespoons of the liquid for later use if needed. This step prevents sogginess in the cake.
- Mix Dry Ingredients: In a medium bowl, whisk together gluten-free flour blend, Dutch-processed cocoa powder, baking powder, baking soda, xanthan gum (if needed), salt, espresso powder, and ground cinnamon. Sifting is recommended to ensure lumps are removed and batter gets smooth.
- Combine Wet Ingredients: In a large bowl, whisk vegetable oil, unsweetened applesauce, eggs, granulated sugar, brown sugar, and vanilla extract until smooth. Stir in melted bittersweet chocolate until fully incorporated to create a rich and moist base.
- Mix Gradually: Add half of the dry ingredients to the wet mixture and stir until combined. Pour in the buttermilk and stir gently. Finally, add the remaining dry ingredients and stir until just nearly combined to maintain tenderness.
- Add Zucchini and Chocolate Chips: Fold in shredded zucchini and mini chocolate chips evenly throughout the batter. If batter feels too thick, add 1-2 tablespoons of the reserved zucchini liquid to adjust consistency.
- Bake: Pour batter into a parchment-lined 9-inch square baking pan. Bake at 350°F (175°C) for 35-40 minutes. Check doneness with a toothpick; it should come out with a few moist crumbs but no wet batter. Avoid overbaking.
- Cool Completely: Let the cake cool in the pan for 15 minutes. Use the parchment overhang to lift the cake onto a cooling rack. Cool completely before frosting or serving to preserve texture and structure.
Notes
- Removing excess moisture from zucchini is critical to prevent soggy cake texture.
- Using Dutch-processed cocoa powder gives this cake a rich chocolate flavor and smooth texture.
- Xanthan gum helps with structure in gluten-free baking; omit only if your flour blend already contains it.
- Check cake doneness early to avoid overbaking as gluten-free cakes can dry out quickly.
- Chocolate chips add structure and texture, counteracting crumbliness common in gluten-free cakes.
- Allowing full cooling before frosting ensures clean frosting application and better final texture.
