Ingredients for the Ultimate Chocolate Zucchini Cake

For the Cake:

• 2 cups (250g) all-purpose flour (spooned & leveled)
• 3/4 cup (62g) unsweetened natural cocoa powder
• 2 teaspoons baking soda
• 1/2 teaspoon baking powder
• 1 teaspoon espresso powder (optional)
• 1/2 teaspoon salt
• 1 cup (240ml) canola or vegetable oil
• 1 cup (200g) granulated sugar
• 3/4 cup (150g) packed light or dark brown sugar
• 4 large eggs, at room temperature
• 1/3 cup (80g) sour cream or plain yogurt
• 2 teaspoons pure vanilla extract
• 3 cups (about 360g) shredded zucchini (lightly blotted)
• 1 cup (180g) semi-sweet chocolate chips

For the Chocolate Buttercream:

• 1 and 1/4 cups (282g) unsalted butter, softened
• 3 and 1/2 cups (420g) confectioners’ sugar
• 3/4 cup (62g) unsweetened cocoa powder (natural or Dutch-process)
• 3–5 tbsp (45–75ml) heavy cream, whole milk, or half-and-half
• 1/4 teaspoon salt
• 1 teaspoon pure vanilla extract
• Optional: chocolate chips or chocolate sprinkles for topping

Step-by-Step Instructions

1. Prep the Pans & Oven

Preheat the oven to 350°F (177°C). Grease two 9-inch round cake pans. Line the bottoms with parchment paper rounds and grease the paper. This ensures the cakes release cleanly.

2. Make the Cake Batter

In a large bowl, whisk together flour, cocoa powder, baking soda, baking powder, espresso powder (if using), and salt.

In another large bowl, use a hand or stand mixer to beat together the oil, granulated sugar, brown sugar, eggs, sour cream, and vanilla extract until well blended. Add in the shredded zucchini and mix until combined.

Slowly add the dry ingredients to the wet ingredients and beat on medium speed until fully incorporated. The batter will be thick. Fold in the chocolate chips.

3. Bake

Divide the batter evenly between the two prepared pans. Bake for 28–32 minutes, or until the tops spring back when lightly touched, or a toothpick inserted comes out clean.

Allow the cakes to cool in their pans for 1 hour before removing and placing on a wire rack to cool completely.

Making the Chocolate Buttercream

With a mixer, beat the softened butter on medium speed for 2 minutes until creamy. Add in the confectioners’ sugar, cocoa powder, 3 tablespoons cream, salt, and vanilla. Beat on low speed at first, then increase to high and mix until smooth and fluffy.

If frosting is too thick, add more cream 1 tablespoon at a time. If too thin, add more sugar or cocoa. Taste and adjust salt if needed.

Assemble and Decorate

Using a serrated knife, slice off the domed tops of the cakes to level them.

• Place one layer on a cake stand or plate.
• Spread a generous layer of frosting on top.
• Add the second cake layer and frost the top and sides completely.
• Use a piping tip (Wilton 1M or similar) to pipe swirls if desired.
• Decorate with chocolate chips or sprinkles.

Tips for a Perfect Chocolate Zucchini Cake

• Blot the Zucchini: Lightly press shredded zucchini with paper towels to avoid extra moisture that may alter the cake texture.
• Espresso Powder: Enhances the chocolate flavor without tasting like coffee.
• Use Natural Cocoa: For a richer, deeper chocolate color and taste.
• Try it with a twist: Want something closer to Zucchini Cakes Recipe or Zucchini Recipes Dessert? Add a swirl of cream cheese frosting or layer in sliced bananas for extra sweetness.

Storage Instructions

• Room Temperature: Store covered for up to 2 days.
• Refrigerator: Keeps well for up to 5 days in an airtight container.
• Freezer: Freeze cake layers (unfrosted) for up to 2 months. Thaw and frost fresh.
