Ingredients

Scale

Main Ingredients:

  • 2 medium ripe bananas, mashed (about 3/4 cup)
  • 2 small zucchini, grated (about 1 1/2 cups)
  • 1 1/2 cups all-purpose flour
  • 1 cup semi-sweet or dark chocolate chunks

Wet Ingredients:

  • 1/2 cup melted coconut oil
  • 1/3 cup honey
  • 2 eggs
  • 2 teaspoons vanilla extract

Dry and Seasoning Ingredients:

  • 1 1/2 teaspoons baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon kosher salt

Frosting Ingredients:

  • 4 ounces (113 grams) cream cheese, at room temperature
  • 1/2 cup (1 stick or 113 grams) salted butter, at room temperature
  • 1 1/2 cups confectioners sugar
  • 1 tablespoon instant coffee powder
  • 2 teaspoons vanilla extract

Instructions

  1. Preheat the oven to 350°F and prepare an 8-inch square baking pan by lining it with parchment paper.
  2. Drain excess moisture from shredded zucchini by wrapping it in a clean kitchen towel and gently squeezing out the water.
  3. Combine mashed bananas, coconut oil, honey, eggs, and vanilla in a large mixing bowl, whisking until thoroughly blended.
  4. Gradually incorporate flour, baking soda, cinnamon, and salt into the wet mixture, stirring until just combined.
  5. Fold in the drained zucchini and chocolate pieces, ensuring even distribution throughout the batter.
  6. Transfer the batter to the prepared pan, spreading it evenly and smoothing the top with a spatula.
  7. Bake for 35-40 minutes, checking for doneness by inserting a toothpick into the center – it should come out clean with minimal crumbs.
  8. Allow the cake to cool in the pan for 15 minutes, then carefully remove and transfer to a wire rack to cool completely.
  9. For the frosting, dissolve instant coffee in hot water and set aside.
  10. Using a stand mixer, cream together cream cheese and butter until light and airy, approximately 2 minutes.
  11. Gradually add confectioners’ sugar, dissolved coffee, and vanilla, beating until the frosting becomes smooth and fluffy.
  12. Once the cake has cooled, generously spread the coffee-infused cream cheese frosting over the top.
  13. Slice into squares and serve at room temperature.

Notes

  • Squeeze zucchini thoroughly to prevent excess moisture, which could make the cake soggy and affect its texture.
  • Use ripe, spotty bananas for maximum natural sweetness and deeper banana flavor in the cake.
  • Choose dark chocolate with 70% cocoa content for a rich, intense chocolate taste that complements the zucchini’s subtle earthiness.
  • Replace honey with maple syrup or agave nectar for alternative natural sweeteners that work equally well in this recipe.
