Ingredients
2 cups all-purpose flour
¾ cup unsweetened natural cocoa powder
2 teaspoons baking soda
½ teaspoon baking powder
1 teaspoon espresso powder (optional)
½ teaspoon salt
1 cup (240 ml) canola or vegetable oil
1 cup granulated sugar
¾ cup packed light or dark brown sugar
4 large eggs, room temperature
⅓ cup sour cream or plain yogurt, room temperature
2 teaspoons pure vanilla extract
3 cups (about 360g) shredded zucchini (lightly blotted)
1 cup semi-sweet chocolate chips
Chocolate Buttercream Frosting:
1¼ cups unsalted butter, softened
3½ cups confectioners’ sugar
¾ cup unsweetened cocoa powder
3–5 tablespoons heavy cream (to preference)
¼ teaspoon salt
1 teaspoon pure vanilla extract
Optional decoration: chocolate chips and/or sprinkles
Instructions
Preheat oven to 350 °F (177 °C). Grease two 9‑inch round cake pans, line with parchment rounds, and grease the parchment.
In a large bowl, whisk together flour, cocoa, baking soda, baking powder, espresso powder (if using), and salt.
In another bowl, beat oil, granulated sugar, brown sugar, eggs, sour cream (or yogurt), and vanilla until smooth.
Gently fold in the shredded zucchini, then add the dry ingredients and mix on medium until just combined. Fold in chocolate chips.
Divide batter evenly between pans. Bake for 28–32 minutes, or until a toothpick comes out clean. Cool in pans for 1 hour, then transfer to a rack to cool completely.
For the frosting, beat butter until creamy, about 2 minutes. Gradually add confectioners’ sugar, cocoa, 3 tbsp cream, salt, and vanilla. Beat on low for 30 seconds, increase to high, and whip until smooth. Adjust thickness with more cream or sugar as needed.
To assemble, level cake tops, spread frosting between layers, then frost top and sides. Decorate as desired.
Store at room temp for up to 2 days, refrigerate up to 5 days, or freeze (wrapped) up to 2 months.
Notes
Don’t over-blot zucchini—some moisture is key for the perfect texture.
Room-temperature ingredients help ensure even mixing and structure.
Avoid overmixing after combining wet and dry ingredients to prevent a dense cake.
The frosting’s consistency can be adjusted with extra cream (thinner) or sugar (thicker).
For an easy adaptation, bake as 24–30 cupcakes (18–22 mins) or a 9×13 sheet cake (about 45 mins).
