  • 2 small zucchini, grated (about 1 1/2 cups grated, before squeezing out water)
  • 2 medium ripe bananas, mashed (about 3/4 cup mashed)
  • 1/2 cup melted coconut oil
  • 1/3 cup honey
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon ground cinnamon (optional)
  • 1/2 teaspoon kosher salt
  • 1 cup semi-sweet or dark chocolate chunks


  • 4 ounces cream cheese, at room temperature
  • 1/2 cup (1 stick) salted butter, at room temperature
  • 1 ½ cups confectioners’ sugar
  • 1 tablespoon instant coffee powder
  • 2 teaspoons vanilla extract


  1. Preheat oven to 350° F. Line an 8-inch square baking pan with parchment paper.
  2. Place the shredded zucchini in a clean towel, then squeeze out any excess water.
  3. In a large mixing bowl, stir together the mashed bananas, coconut oil, honey, eggs, and vanilla until combined. Add the flour, baking soda, cinnamon, and salt, mix until just combined. Stir in the zucchini. Fold in the chocolate. Pour the batter into the prepared bread pan. Bake for 30-40 minutes, or until the center is just set. Remove and let cool for at least 30 minutes before frosting.
  4. To make the frosting, dissolve the instant coffee in 1 tablespoon hot water. In a stand mixer, beat together the cream cheese and butter until light and fluffy, about 2 minutes. Add the confectioners’ sugar, coffee, and vanilla. Beat until the frosting is light and fluffy, 2 to 4 minutes more.
  5. Spread the frosting over the cake. Slice, snack, and enjoy!

Serving Tips:

  1. Cool Completely Before Serving: Allow the Chocolate Zucchini Banana Cake to cool completely before slicing and serving. This helps to set the texture and prevent it from crumbling when sliced.
  2. Dust with Powdered Sugar: Just before serving, dust the top of the cake with powdered sugar for a decorative touch. This adds a hint of sweetness and enhances the presentation of the cake.
  3. Pair with Toppings: Serve slices of the cake on dessert plates and consider pairing them with a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of chocolate sauce for an extra indulgent treat.
  4. Slice Carefully: When slicing the cake, use a sharp knife to ensure clean and neat slices. Wiping the knife clean between each slice will help maintain the cake’s appearance.
  5. Serve with Coffee or Tea: Chocolate Zucchini Banana Cake pairs beautifully with a cup of coffee or tea. Enjoy a slice alongside your favorite hot beverage for a cozy and satisfying dessert experience.

Storage Tips:

  1. Refrigeration: Store any leftover Chocolate Zucchini Banana Cake in an airtight container or tightly wrapped in plastic wrap. Refrigerate for up to 3-4 days to maintain freshness and prevent the cake from drying out.
  2. Freezing: If you have leftover cake that you won’t be able to consume within a few days, consider freezing individual slices for future enjoyment. Wrap each slice tightly in plastic wrap and then aluminum foil before placing them in a freezer-safe container or resealable plastic bag. Freeze for up to 1-2 months.
  3. Thawing Frozen Cake: When ready to enjoy frozen cake slices, transfer them to the refrigerator to thaw overnight. This gradual thawing process helps preserve the cake’s texture and prevents it from becoming soggy.
  4. Room Temperature Storage: If you prefer to store the cake at room temperature, keep it in an airtight container in a cool, dry place away from direct sunlight and heat sources. Be mindful that the cake may dry out more quickly at room temperature compared to refrigeration.
  5. Refresh Before Serving: Before serving leftover refrigerated or frozen cake slices, you can refresh them by briefly warming them in the microwave for a few seconds or in a preheated oven at a low temperature. This helps restore the cake’s moisture and freshness.


  1. Can I taste the zucchini in the cake?
    • No, you can’t taste the zucchini in the cake. Grated zucchini adds moisture and texture to the cake without imparting a distinct flavor. It blends seamlessly with the other ingredients, ensuring a delicious and moist cake.
  2. Can I use frozen bananas for this recipe?
    • Yes, you can use frozen bananas for Chocolate Zucchini Banana Cake. Thaw the frozen bananas completely before mashing them for the recipe. Frozen bananas may be more watery than fresh ones, so drain any excess liquid before adding them to the batter.
  3. Can I omit the cocoa powder to make a regular zucchini banana cake?
    • Yes, you can omit the cocoa powder if you prefer a regular zucchini banana cake without chocolate flavor. Simply exclude the cocoa powder from the recipe, and proceed with the remaining ingredients and instructions as directed.
  4. How do I know when the cake is done baking?
    • To check if the cake is done baking, insert a toothpick into the center of the cake. If it comes out clean or with a few moist crumbs clinging to it, the cake is ready. Avoid over-baking, as it can result in a dry cake.
  5. Can I substitute other vegetables for zucchini in this recipe?
    • While zucchini works exceptionally well in this recipe due to its mild flavor and moisture content, you can experiment with other vegetables such as grated carrots or shredded squash. Keep in mind that different vegetables may alter the texture and flavor of the cake slightly.
