Description
This indulgent three-layer cake features a rich cocoa crumb enriched with freshly grated zucchini for an incredibly moist texture. Finished with a decadent chocolate ganache buttercream, it is the perfect balance of deep flavor and velvety softness.
Ingredients
- 2 cups all-purpose flour
- 1 cup unsweetened natural cocoa powder
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1 tablespoon espresso powder
- 1 cup vegetable oil
- 1 cup granulated sugar
- 1 cup light brown sugar
- 3 large eggs
- 1 cup sour cream
- 1 teaspoon vanilla extract
- 2 cups finely grated zucchini
- 2 cups semi-sweet chocolate chips
- 1/2 cup butter, softened
- 3 cups powdered sugar
- 1/3 cup heavy cream
Instructions
- Prep pans. Preheat the oven to 350ºF and grease three 8-inch cake pans, lining the bottoms with parchment paper.
- Whisk dry ingredients. Combine flour, cocoa powder, baking soda, baking powder, salt, and espresso powder in a large bowl.
- Mix wet base. Blend vegetable oil, both sugars, eggs, sour cream, and vanilla extract until smooth, then fold in the grated zucchini.
- Combine batter. Stir the wet mixture into the dry ingredients, fold in the chocolate chips, and divide evenly into the prepared pans.
- Bake layers. Bake for 35 to 40 minutes until a toothpick comes out clean, then cool in pans for 10 minutes before transferring to a wire rack.
- Create ganache base. Melt chocolate chips with one-third cup of heavy cream in short microwave intervals until glossy and smooth.
- Prepare buttercream. Beat the softened butter and salt until creamy, then incorporate the cocoa powder, powdered sugar, remaining cream, vanilla, and cooled ganache.
- Assemble cake. Spread buttercream between each layer and cover the top and sides, smoothing with a scraper for a clean finish.
Notes
- Use the fine side of a box grater for the zucchini so it fully incorporates into the batter.
- Always use the spoon-and-level method for measuring flour to avoid a dense, dry cake crumb.
- Bring eggs and sour cream to room temperature to ensure the batter emulsifies perfectly.
- Chill the assembled cake for thirty minutes before slicing to achieve clean, professional-looking edges.
