For the Cake:
- ½ cup unsalted butter, softened
- ½ cup vegetable oil
- 1 ¾ cups granulated sugar
- 1 tsp pure vanilla extract
- 1 tsp baking soda
- ½ tsp baking powder
- ½ tsp salt
- 2 large eggs
- ½ cup sour cream
- 2 ½ cups all-purpose flour
- ¾ cup Dutch-process cocoa powder see note
- 2 ½ cups shredded zucchini, squeezed dry
- ⅔ cup chocolate chips
For the Ganache:
- ¾ cup heavy cream
- 10 oz semi-sweet chocolate chips
Preheat oven to 325°F and grease a 9x13-inch baking pan.
In a large bowl, cream butter, oil, sugar, vanilla, baking soda, baking powder, and salt.
Add eggs, then alternate adding sour cream and flour. Mix in cocoa powder until smooth.
Fold in shredded zucchini and chocolate chips.
Spread batter evenly in pan. Bake 30–35 minutes until top springs back. Cool completely.
For ganache: Heat cream in saucepan until simmering. Remove from heat and pour over chocolate chips.
Stir until smooth and glossy. Let cool slightly.
Pour ganache over cake and spread evenly. Let set 30 minutes before slicing.
If using regular cocoa powder instead of Dutch-process, add an extra ½ tsp of baking soda. For a fun twist, fold in chopped nuts with the chocolate chips to add crunch. This Chocolate Zucchini Cake is freezer-friendly too!
