Ingredients

Scale

Wet Ingredients

  • 1 cup mashed ripe bananas (about 2 bananas)
  • 1 cup shredded zucchini (squeezed dry)
  • 2 large eggs
  • ½ cup vegetable oil
  • ½ cup brown sugar
  • ¼ cup granulated sugar
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 cup all-purpose flour
  • ½ cup whole wheat flour
  • â…“ cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon

Add-ins

  • ½ cup mini chocolate chips (plus more for topping, optional)


Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking pan or line it with parchment paper to prevent the cake from sticking and ensure even cooking.
  2. Mix Wet Ingredients: In a large bowl, whisk together mashed bananas, shredded and squeezed dry zucchini, eggs, vegetable oil, brown sugar, granulated sugar, and vanilla extract until the mixture is smooth and well combined, ensuring a consistent batter.
  3. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, whole wheat flour, unsweetened cocoa powder, baking soda, baking powder, salt, and ground cinnamon to evenly distribute the leavening agents and spices.
  4. Combine Wet and Dry Mixtures: Gradually stir the dry ingredient mixture into the wet ingredients, mixing just until combined to avoid overmixing which can make the cake dense.
  5. Fold in Chocolate Chips: Gently fold the mini chocolate chips into the batter, reserving some for sprinkling on top if desired for extra chocolate flavor and texture.
  6. Pour and Spread Batter: Pour the batter into the prepared baking pan and spread it evenly with a spatula to ensure uniform baking.
  7. Bake the Cake: Bake in the preheated oven for 35 to 40 minutes, or until a toothpick inserted into the center comes out with moist crumbs, indicating the cake is cooked but still moist inside.
  8. Cool and Serve: Allow the cake to cool completely in the pan on a wire rack before slicing to allow the flavors to set and make slicing easier.

Notes

  • Be sure to squeeze the zucchini well to avoid excess moisture which can make the cake soggy.
  • This cake is even better the next day after the flavors have melded together.
  • Can be made dairy-free by using non-dairy chocolate chips.
