Ingredients
Scale
Cake Base:
- 3 cups all-purpose flour
- 2 cups granulated sugar
- 1 cup unsweetened cocoa powder
- 2 cups grated zucchini
- 1 cup chocolate chips
Wet Ingredients:
- 1 ½ cups vegetable oil
- 1 cup buttermilk
- 4 large eggs
- 2 teaspoons vanilla extract
Supporting Ingredients:
- 2 teaspoons baking soda
- 1 teaspoon salt
- 1 teaspoon ground cinnamon
Frosting:
- 1 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 4 cups powdered sugar
- ½ cup milk
Instructions
- Heat your oven to 350°F (175°C). Prepare a 9×13 inch baking pan by greasing and dusting with flour.
- Combine all dry ingredients – flour, sugar, cocoa powder, baking soda, salt, and cinnamon – in a large mixing bowl, whisking thoroughly to distribute evenly.
- Create your wet mixture separately by blending vegetable oil, buttermilk, eggs, and vanilla extract until smoothly integrated.
- Gently fold the wet ingredients into the dry ingredients, stirring just until the batter becomes uniform without overmixing.
- Incorporate the grated zucchini and chocolate chips into the batter, ensuring even distribution throughout.
- Transfer the batter to your prepared pan, using a spatula to spread it evenly and create a level surface.
- Slide the pan into the preheated oven and bake for 30-35 minutes, checking doneness with a wooden skewer that should emerge clean when inserted into the center.
- Remove the cake and allow it to cool completely inside the pan, placed on a wire rack.
- Prepare the frosting by whipping softened butter and peanut butter together until they form a smooth, creamy consistency.
- Gradually introduce powdered sugar and milk into the butter mixture, beating until the frosting reaches a spreadable texture.
- Once the cake has cooled entirely, generously cover the top with your prepared peanut butter frosting.
- Slice into square servings and enjoy your delectable chocolate zucchini creation.
Notes
- Grate zucchini on the large holes of a box grater to ensure moisture and tender texture without large vegetable chunks.
- Pat zucchini with paper towels to remove excess liquid, preventing a soggy cake and maintaining the perfect dense crumb.
- For gluten-free options, substitute all-purpose flour with a 1:1 gluten-free baking blend to keep the cake’s rich chocolate flavor.
- Swap peanut butter frosting with cream cheese frosting if nut allergies are a concern, which adds a tangy complement to the chocolate cake.
