Ingredients

Scale

Cake

  • 2 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 1 3/4 cups packed brown sugar
  • 1/2 cup vegetable oil
  • 1/4 cup melted butter (slightly cooled)
  • 1/2 cup buttermilk
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 cups shredded zucchini (lightly squeezed to remove excess moisture, but not dry)
  • 1 cup chocolate chips

Chocolate Frosting

  • 1 cup unsalted butter (softened)
  • 3 cups powdered sugar
  • 1/3 cup unsweetened cocoa powder
  • 1/4 cup heavy cream (or as needed)
  • 1 teaspoon vanilla extract
  • Pinch salt


Instructions

  1. Preheat and prepare pans: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to prevent sticking.
  2. Mix dry ingredients: In a large bowl, sift together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt. Set aside.
  3. Combine wet ingredients: In another bowl, whisk together the brown sugar, vegetable oil, melted butter, buttermilk, eggs, and vanilla extract until smooth and well combined.
  4. Incorporate zucchini and chocolate chips: Fold the shredded zucchini and chocolate chips into the wet mixture gently to distribute evenly.
  5. Combine wet and dry mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Avoid overmixing to keep the cake tender.
  6. Pour and bake: Divide the batter evenly between the prepared pans. Bake in the preheated oven for about 40 minutes, or until a toothpick inserted in the center comes out clean.
  7. Cool the cakes: Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then turn them out onto wire racks to cool completely before frosting.
  8. Make the frosting: In a large bowl, beat the softened butter until creamy. Gradually add powdered sugar and cocoa powder, mixing well. Add vanilla extract, a pinch of salt, and heavy cream little by little until the frosting reaches a spreadable consistency.
  9. Assemble the cake: Once the cakes are completely cool, spread a layer of frosting on top of one cake layer. Place the second cake layer on top, then frost the top and sides of the entire cake evenly.
  10. Serve: Slice and enjoy your rich and moist chocolate zucchini cake with a delightful chocolate frosting topping.

Notes

  • Ensure zucchini is lightly squeezed but not fully dried to maintain moisture in the cake.
  • Use fresh eggs and buttermilk for best flavor and texture.
  • This cake can be stored covered at room temperature for up to 3 days or refrigerated up to a week.
  • For a vegan option, substitute eggs and butter with plant-based alternatives and use a non-dairy milk in place of buttermilk.
  • Adding chocolate chips enhances the chocolate flavor and adds texture.
