Chocolate zucchini cake is a wonderful way to enjoy a moist, rich chocolate dessert while sneaking in some veggies! The zucchini adds natural moisture and a tender crumb without overpowering the chocolate flavor.

It’s a great way to add nutrition to your cake without compromising on taste. This cake is perfect for family gatherings, birthdays, or anytime you want a chocolaty treat that feels a little healthier.

Unlike a typical chocolate cake, this version uses grated zucchini, which keeps the cake incredibly moist and tender. The addition of cocoa powder ensures a deep chocolate flavor, while a touch of cinnamon adds warmth.

Whether you serve it plain, dusted with powdered sugar, or topped with a luscious chocolate ganache or cream cheese frosting, this cake never disappoints.

How to Make Chocolate Zucchini Cake

Step 1: Preheat and Prepare Pans

Preheat your oven to 350°F (175°C).

Grease and flour a 9×13 inch baking pan or two 8-inch round cake pans.

You can also line pans with parchment paper for easier removal.

Step 2: Mix Dry Ingredients

In a medium bowl, sift together the flour, cocoa powder, baking soda, baking powder, salt, and cinnamon.

Set aside.

Step 3: Combine Sugars and Wet Ingredients

In a large mixing bowl, whisk the granulated sugar, brown sugar, and eggs until well combined.

Add the vegetable oil and vanilla extract, mixing until smooth.

Step 4: Incorporate Dry Ingredients and Zucchini

Gradually add the dry ingredients into the wet mixture, alternating with buttermilk (or yogurt). Start and end with dry ingredients.

Stir gently until just combined.

Fold in the grated zucchini and chocolate chips (if using).

Step 5: Bake the Cake

Pour the batter into the prepared pan(s).

Bake in the preheated oven for 40–50 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.

Baking time may vary depending on pan size and oven.

Step 6: Cool and Frost

Let the cake cool in the pan for 15 minutes, then transfer to a wire rack to cool completely.

If frosting, prepare the cream cheese frosting by beating softened cream cheese and butter until smooth, then gradually add powdered sugar and vanilla.

Spread the frosting evenly over the cooled cake.

Chef’s Notes

Zucchini prep: Use fresh zucchini and grate finely. Squeeze out excess water using a clean kitchen towel or cheesecloth to prevent a soggy cake.

Cocoa powder: Use high-quality unsweetened cocoa powder for best flavor.

Oil substitution: You can use melted coconut oil or a mild-flavored vegetable oil.

Texture: This cake is naturally moist and dense, not dry or crumbly.

Add-ins: Chopped nuts like walnuts or pecans can be added for extra texture.

Frosting options: Cream cheese frosting complements the cake’s flavor well, but whipped cream or a simple dusting of powdered sugar also works.
