Best Ever Chocolate Zucchini Bundt Cake

Ingredients

Gather your ingredients to create this chocolatey delight.

  • 2/3 cup (50g) Dutch-processed cocoa powder (plus more for dusting)
  • 2 1/4 cups (270g) all-purpose flour
  • 1 tsp baking soda
  • 1 tsp kosher salt
  • 1/2 cup (110g) unsalted butter (at room temperature)
  • 1 cup (200g) lightly packed brown sugar
  • 3/4 cup (150g) granulated sugar
  • 1/2 cup (120ml) mild-flavored oil (such as vegetable oil)
  • 1 tsp vanilla extract
  • 2 eggs (at room temperature)
  • 1/2 cup (120g) plain full-fat yogurt or sour cream
  • 2 cups (315g) packed, grated, unpeeled zucchini (do not squeeze out liquid)
  • 4 oz (115g) bittersweet or semisweet chocolate (melted and cooled to room temperature)
  • Chocolate ganache (for topping if desired)

Notes and substitutions:

Using Dutch-processed cocoa powder adds a deep, rich flavor and dark color to the cake, but if you don’t have it on hand, you can substitute with natural cocoa powder; however, the flavor and color may be slightly lighter. Full-fat yogurt or sour cream not only enhances moisture but also adds a tangy richness. If you want a lighter version, you could use low-fat yogurt, but keep in mind it may slightly affect the texture.

How to Make This Recipe Step by Step

  1. Preheat your oven to 325℉ (165˚C). Generously grease a 12-cup Bundt pan and dust it with cocoa powder.
  2. Pro Tip: Dusting with cocoa powder instead of flour gives a seamless finish to your cake.
  3. In a medium bowl, sift together the all-purpose flour, baking soda, kosher salt, and cocoa powder.
  4. Pro Tip: Sifting is essential to remove lumps and ensure an even distribution of ingredients.
  5. In a stand mixer fitted with the paddle attachment, cream the butter on medium-high speed until it’s creamy and smooth, about 1 minute.
  6. Pro Tip: Letting the butter come to room temperature allows it to cream more easily and incorporates air, leading to a lighter texture.
  7. Reduce mixer speed to low. Add both sugars to the butter and mix until incorporated. Drizzle in the mild-flavored oil and vanilla extract, then turn the speed to medium-high and beat until the mixture is light and fluffy, about 5 minutes. Scrape the bowl often for even incorporation.
  8. Pro Tip: Creaming butter and sugars well introduces air into the batter, creating a fluffier cake.
  9. Gradually add the eggs, one at a time, mixing just until combined after each addition. Scrape the bowl after each egg.
  10. Pro Tip: Adding eggs one at a time helps maintain the emulsification of the batter.
  11. Add one-third of the sifted flour mixture to the butter mixture, mixing on low speed just until incorporated. Follow with half the yogurt, mixing until incorporated. Repeat with another one-third of the flour, then the remaining yogurt, and finish with the final one-third of the flour, scraping the bowl and paddle after each addition.
  12. Pro Tip: Mixing carefully prevents overworking the batter, which can lead to a dense cake.
  13. Remove the bowl from the mixer and gently stir in the grated zucchini until evenly distributed. Then, fold in the melted chocolate until combined.
  14. Pro Tip: Avoid squeezing the zucchini to keep all the moisture it provides.
  15. Pour the batter into the prepared Bundt pan, tapping it on the counter several times to ensure it settles perfectly.
  16. Pro Tip: Tapping the pan removes air bubbles that could create uneven surfaces.
  17. Bake in the preheated oven until a cake tester or toothpick comes out with moist crumbs, about 1 hour. Do not overbake.
  18. Pro Tip: Keep an eye on the cake in the last 10 minutes to ensure it doesn’t dry out.
  19. Allow the cake to cool in the pan for 10 minutes before carefully flipping it onto a serving plate. Dust the top with cocoa powder or drizzle with chocolate ganache if desired.
  20. Pro Tip: The cocoa dusting adds an elegant touch and enhances the chocolate flavor.

Guaranteed Success Tips

To ensure that your baking experience is flawless, keep these tips in mind:

Frequently Asked Questions

  1. Can I use another type of oil?
  2. Yes! You can replace vegetable oil with coconut oil or canola oil for a similar result. Just make sure the coconut oil is melted and cooled before adding it to the batter.
  3. Is the zucchini taste noticeable?
  4. Not at all! The zucchini adds moisture and texture but doesn’t impart a strong flavor. It blends seamlessly with the chocolate.
  5. What if I don’t have a Bundt pan?
  6. You can use a 9×13-inch baking dish instead. Just remember to adjust the baking time, as a different size will require more or less time in the oven.
  7. Why is my cake sinking in the middle?
  8. This can happen if the batter is overmixed or if there isn’t enough flour. Ensure you measure accurately and mix gently.
  9. Can I make this cake gluten-free?
  10. Yes! Substitute all-purpose flour with a gluten-free blend, ensuring it includes xanthan gum for the best texture.
  11. What’s the best way to serve this cake?
  12. It’s delightful on its own but pairs beautifully with whipped cream or ice cream for added richness.
  13. How can I tell when my cake is done?
  14. A toothpick inserted into the center should come out with a few moist crumbs, but not wet batter.

This recipe truly captures the essence of comfort food, delivering a delightful experience with every bite. Enjoy the rich chocolate flavor and surprise your friends and family with this incredible chocolate zucchini Bundt cake!
