Ingredients

Scale
  • 2 cups (240 grams) all-purpose flour
  • 1/2 teaspoon cinnamon
  • 1/2 teaspoon salt
  • 1 1/2 teaspoons baking soda
  • 1/2 cup (42 grams) unsweetened cocoa powder
  • 1 teaspoon espresso powder
  • 1/2 cup (99 grams) canola oil
  • 1 cup (198 grams) granulated sugar
  • 1/4 cup (54 grams) brown sugar
  • 3 large eggs
  • 2 teaspoons vanilla extract
  • 1/2 cup (113.5 grams) sour cream
  • 3 cups (410 grams) grated zucchini
  • 3/4 cup (127.5 grams) chocolate chips
  • 1 cup (170 grams) chopped chocolate (for ganache)
  • 1/2 cup (113 grams) heavy cream (for ganache)
  • Mini chocolate chips for decoration (optional)

Instructions

  1. Preheat the oven to 325°F and grease a 10-cup metal bundt pan.
  2. In a mixing bowl, beat the oil, granulated sugar, brown sugar, and eggs on medium-low speed for about 2 minutes.
  3. Add vanilla extract and sour cream, mixing until well combined.
  4. Fold in the grated zucchini.
  5. In a separate bowl, whisk together flour, cinnamon, baking soda, salt, cocoa powder, and espresso powder.
  6. Gently stir the dry ingredients into the wet mixture until just combined. Do not overmix.
  7. Fold in the chocolate chips.
  8. Pour the batter into the prepared bundt pan, tap to remove air bubbles.
  9. Bake for 50-60 minutes until a tester comes out with moist crumbs.
  10. Cool in the pan on a wire rack for 10 minutes, then invert to release the cake.
  11. For ganache, microwave chopped chocolate and heavy cream at 50% power in 30-second intervals until smooth.
  12. Let the ganache thicken slightly, then pour over the cooled cake and top with mini chocolate chips if desired.

Notes

  • No need to peel zucchini; skin adds nutrients and texture.
  • Use freshly grated zucchini for best moisture retention.
  • Bring ingredients to room temperature before baking.
  • Generously grease the bundt pan to avoid sticking.
  • Ganache can be poured once cake is completely cooled.
