Step-by-Step Instructions
1. Prepare the Cake Layers:
- Preheat oven to 350°F (180°C). Line three 8-inch cake pans with parchment paper and grease the sides.
- In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
- In a large bowl, mix melted butter, vegetable oil, granulated sugar, brown sugar, and vanilla extract until well combined.
- Add eggs and sour cream to the wet mixture and mix until smooth. Then add milk and mix again.
- Gradually add dry ingredients to the wet mixture, mixing just until combined.
- Stir in hot water until the batter is smooth.
- Gently fold in shredded zucchini without overmixing.
- Divide the batter evenly among the prepared pans and bake for 28–33 minutes, or until a toothpick inserted in the center comes out clean.
- Allow cakes to cool in pans for 3–4 minutes, then transfer to wire racks to cool completely.
2. Make the Chocolate Buttercream:
- In a large mixing bowl, beat the butter until smooth.
- Add 3 cups of powdered sugar and the cocoa powder; mix until well combined.
- Add vanilla extract and 3 tablespoons of heavy cream; mix until smooth.
- Add the remaining 3 cups of powdered sugar and a pinch of salt; mix until well combined.
- Add additional heavy cream as needed to achieve desired consistency.
3. Assemble the Cake:
- Level the tops of the cooled cakes if necessary.
- Place the first cake layer on a serving plate and spread about ¾ cup of frosting evenly on top.
- Repeat with the second layer.
- Place the final layer on top and frost the top and sides of the cake.
- For a decorative touch, press mini chocolate chips into the bottom half of the sides and sprinkle some on top.
Tips for Success
- Don’t Overmix: Overmixing can lead to a dense cake. Mix just until ingredients are combined.
- Zucchini Prep: Shred zucchini using the large holes of a box grater and gently squeeze out excess moisture.
- Frosting Consistency: Adjust the amount of heavy cream to achieve a spreadable frosting.
