How to Make Great Grandma's Chocolate Zucchini Cake

  1. Preheat oven to 325°F (160°C). Grease and flour a 9x13 inch baking pan.
  2. In a large bowl, cream together 1 cup (2 sticks) softened unsalted butter, ½ cup vegetable oil, 2 cups granulated sugar, and 4 large eggs until light and fluffy. Beat in 1 teaspoon vanilla extract.
  3. In a small bowl, combine ¼ cup buttermilk and 1 tablespoon lemon juice. Let stand for 5 minutes to curdle.
  4. Gradually add the buttermilk mixture to the creamed mixture, mixing on low speed until just combined.
  5. In a separate bowl, whisk together 2 teaspoons baking powder, 1 teaspoon baking soda, 1 teaspoon ground cinnamon, ½ teaspoon ground cloves, 2 cups all-purpose flour, and ¾ cup unsweetened cocoa powder. Sift three times for a lighter cake.
  6. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Gently fold in 2 cups grated zucchini.
  7. Pour batter into the prepared pan and sprinkle evenly with 1 cup chocolate chips.
  8. Bake for 40-45 minutes, or until a wooden skewer inserted into the center comes out clean. Let cool completely before frosting (optional).
