The zucchini keeps the cake soft without adding a strong vegetable taste, making it a crowd-pleaser for all ages.
Ingredients
- 2 cups finely shredded zucchini (about 1 medium zucchini, squeezed dry)
- 1 ¾ cups gluten free all-purpose flour blend (with xanthan gum included)
- ½ cup unsweetened cocoa powder (preferably Dutch-processed)
- 1 ½ teaspoons baking powder (gluten free)
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup granulated sugar
- ½ cup packed light brown sugar
- 3 large eggs, at room temperature
- ½ cup vegetable oil (or melted coconut oil)
- 1 teaspoon pure vanilla extract
- ½ cup plain Greek yogurt or dairy-free yogurt alternative
- ½ cup mini chocolate chips (optional, for extra chocolate bursts)
- Powdered sugar or gluten free chocolate ganache, for garnish (optional)
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour an 8-inch square baking pan with gluten free flour or line it with parchment paper for easy removal.
- Place the shredded zucchini in a clean kitchen towel or cheesecloth and squeeze out as much excess moisture as possible. Set aside.
- In a medium bowl, whisk together the gluten free flour, cocoa powder, baking powder, baking soda, and salt until well combined.
- In a large mixing bowl, beat the eggs with both sugars until the mixture is pale and slightly fluffy, about 2-3 minutes.
- Stir in the vegetable oil, vanilla extract, and Greek yogurt until fully incorporated.
- Gradually add the dry ingredients to the wet ingredients, folding gently with a spatula until just combined. Avoid overmixing to keep the cake tender.
- Fold in the shredded zucchini and mini chocolate chips, if using, distributing evenly through the batter.
- Pour the batter into the prepared pan and smooth the top with a spatula.
- Bake for 40-45 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
- Remove from oven and let cool in the pan on a wire rack for 15 minutes, then transfer to the rack to cool completely before slicing.
- Optional: dust with powdered sugar or drizzle with a simple gluten free chocolate ganache before serving.
Tips
- Zucchini prep: Removing excess moisture from zucchini is key to preventing a soggy cake. Use a fine grater and squeeze firmly with a towel.
- Flour blend: Use a reliable gluten free all-purpose flour that contains xanthan gum or guar gum to provide structure. If your blend lacks this, add ½ teaspoon xanthan gum.
- Oil alternatives: You can swap vegetable oil for melted coconut oil or light olive oil for different flavor profiles. Avoid butter to keep the texture moist and tender.
- Don’t overmix: Gluten free batters can become gummy if overworked. Mix just until the ingredients come together for the best crumb.
Serving Suggestions
This chocolate zucchini cake is excellent served slightly warm or at room temperature. Pair it with a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent dessert. For a lighter option, serve with fresh berries or a drizzle of raspberry sauce to complement the chocolate’s richness. It also works well as a snack with a cup of coffee or tea.
Variations
You can customize this recipe in several ways to suit your taste or dietary needs. Add chopped nuts such as walnuts or pecans for crunch. Substitute the cocoa powder with carob powder for a caffeine-free version. For a dairy-free cake, replace the Greek yogurt with coconut yogurt and use a dairy-free chocolate chip. To make it more festive, fold in dried cherries or orange zest to brighten the flavor.
Storage and Reheating
Store the cake tightly wrapped in plastic wrap or in an airtight container at room temperature for up to 3 days. To extend freshness, refrigerate for up to 5 days; just allow the cake to come to room temperature before serving. For longer storage, freeze the whole cake or individual slices wrapped in plastic and foil for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat slices in a microwave for 15-20 seconds or in a 300°F (150°C) oven for 10 minutes to restore softness. Avoid overheating as gluten free cakes can dry out quickly.
Frequently Asked Questions
Can I use regular zucchini instead of shredded?
Yes, but shredding the zucchini ensures even moisture distribution and a tender crumb. Larger pieces may create uneven texture and pockets of moisture.
Is it necessary to squeeze out the zucchini moisture?
Absolutely. Excess water from zucchini can make the cake soggy and cause it not to bake properly. Use a towel to wring out as much liquid as possible before adding it to the batter.
What if I don’t have a gluten free flour blend?
You can make your own blend using rice flour, potato starch, and tapioca starch, but it’s best to use a blend with xanthan gum included for structure. Adding ½ teaspoon xanthan gum to your flour mix helps mimic gluten’s binding properties.
Can I make this cake vegan?
Yes, with some substitutions. Replace eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) and use a dairy-free yogurt. Use oil instead of butter and ensure chocolate chips are dairy-free.
Why is my cake dense or gummy?
This usually happens if the batter is overmixed or if there’s too much moisture in the zucchini. Make sure to squeeze out excess water and mix only until combined. Also, check your leavening agents are fresh for proper rise.
Can I double this recipe?
Yes, double all ingredients and bake in a 9×13-inch pan. Baking time may increase to about 50-55 minutes; test doneness with a toothpick as usual.
This gluten free chocolate zucchini cake blends healthful ingredients with indulgent chocolate flavor, making it a versatile treat for any occasion. The balance of moisture and crumb texture is key, and with these tips and variations, you can confidently bake a delicious cake that everyone can enjoy.
