Ingredients You’ll Need
- 1 (15.25-ounce) box devil’s food cake mix: I recommend using Duncan Hines for a rich flavor, though any brand will work. This forms the cake’s base.
- ¾ cup canola or vegetable oil: This adds moisture and richness. You can also use melted coconut oil if you prefer.
- ¾ cup sour cream: Sour cream deepens the flavor and keeps the cake moist. Plain Greek yogurt can be a good substitute.
- 3 large eggs: Eggs provide structure and help the cake rise. Make sure they are at room temperature for best results.
- 2 cups shredded zucchini (about 2 medium): Freshly shredded zucchini is crucial for the moisture and subtle sweetness. Squeeze out excess water before measuring to avoid a soggy cake.
- 2 cups semi-sweet chocolate chips: These give that luxurious chocolate flavor; feel free to mix in milk chocolate or dark chocolate chips for a different twist.
- ¾ cup heavy cream: This is used to create a glossy ganache that tops the cake. You can substitute with coconut cream for a dairy-free option.
How to Make Zucchini Chocolate Bundt Cake
Preheat the Oven: Preheat your oven to 350 degrees F (175 degrees C). Grease a 10- to 12-cup Bundt pan with baking spray or butter and flour to prevent sticking.
Mix the Batter: In a large mixing bowl, combine the devil’s food cake mix, ¾ cup of canola or vegetable oil, ¾ cup sour cream, and 3 large eggs. Mix until mostly smooth, ensuring no lumps remain—about 2 minutes by hand or 1 minute using a hand mixer on low speed.
Add the Zucchini and Chocolate Chips: Gently fold in the shredded zucchini and 1 cup of the semi-sweet chocolate chips. This tender fold helps maintain the light texture of the cake.
Pour and Smooth: Pour the batter into the prepared Bundt pan, smoothing the top with a spatula to ensure even baking.
Bake: Place the pan in the oven and bake for 45 to 55 minutes. Start checking at the 45-minute mark; the cake is done when a toothpick inserted in the center comes out clean with just a few moist crumbs.
Cool the Cake: Once done, allow the cake to cool in the pan for 10 to 15 minutes. This short resting period prevents it from breaking apart when you flip it out. Then, turn the cake out onto a wire rack to cool completely.
Make the Ganache: In a small saucepan, heat the heavy cream until it’s steaming, but not boiling. Pour the hot cream over the remaining 1 cup of chocolate chips in a heatproof bowl and let it sit for 1 to 2 minutes. Stir until smooth and shiny.
Finish the Cake: Once the cake has cooled completely, pour the ganache over the top, allowing it to drip down the sides. Let it set for a few minutes before slicing, so the ganache firms up just a bit.
Storing & Reheating
To store your Zucchini Chocolate Bundt Cake, keep it in an airtight container at room temperature for up to 3 days. If you need it to last longer, refrigerate it for up to a week, carefully wrapped to maintain moisture. For freezing, wrap the cake tightly in plastic wrap and aluminum foil, then store it in the freezer for up to 3 months. When you’re ready to enjoy, thaw it at room temperature or pop it in the microwave at low power for a few seconds. Be aware that the texture may change slightly upon thawing, but a quick heat will refresh its taste!
Chef’s Helpful Tips
- Avoid overmixing the batter to keep the cake soft and fluffy.
- Make sure to squeeze excess moisture from the zucchini before adding it to the batter for optimal texture.
- Use room temperature eggs for better emulsification and mixing.
- If you’re aiming for a richer flavor, consider adding a teaspoon of vanilla extract to the batter.
- Allow the cake to cool in the pan longer if it seems delicate to prevent breaking during the transfer.
The combination of chocolate and zucchini might sound unusual, yet this Zucchini Chocolate Bundt Cake will surely turn out to be a delightful hit at your next gathering. It’s rich, moist, and completely enjoyable, whether served as a dessert after dinner, an afternoon snack, or even breakfast treats for the family. Plus, the added health bonus of vegetables makes it even more satisfying.

Recipe FAQs
Can I use other types of cake mix?
Absolutely! While devil’s food cake mix provides the densest chocolate flavor, you can also try chocolate or even a spice cake mix for a different spin. Each will bring a unique flavor profile to this recipe.
How do I store leftovers?
You can keep any leftover cake in an airtight container at room temperature for up to 3 days. If you want to prolong its life, refrigerate it for up to a week, or freeze for up to 3 months.
Can I make this cake ahead of time?
Definitely! You can bake the cake a day in advance and store it wrapped to keep it fresh. Drizzle the ganache on the day you plan to serve it for a beautiful presentation.
Does the zucchini affect the flavor?
Not at all! The zucchini adds moisture and a subtle sweetness but is virtually undetectable in flavor. It enriches the cake without overpowering the delicious chocolate taste.
