Ingredients You’ll Need
- 1 (15.25-ounce) box devil’s food cake mix – This forms the base of our cake. Duncan Hines offers great taste, but feel free to use your favorite brand.
- ¾ cup canola or vegetable oil – Adding moisture, this oil helps create that rich texture. You can substitute with melted coconut oil if desired.
- ¾ cup sour cream – This ingredient adds tanginess and moisture. Greek yogurt works well as a substitute if you need a healthier option.
- 3 large eggs – The eggs bind everything together; fresh eggs at room temperature give the best rise.
- 2 cups shredded zucchini (about 2 medium) – Zucchini keeps the cake moist and soft while offering essential nutrients. No need to peel; just shred and add!
- 2 cups semi-sweet chocolate chips (divided) – Use these to create a melty chocolate experience. Dark chocolate chips can boost the flavor even more.
- ¾ cup heavy cream – Used for the ganache, it creates a beautifully smooth and shiny topping. Light cream will work in a pinch but may not be as rich.
How to Make Zucchini Chocolate Bundt Cake
- Preheat the Oven: Start by preheating your oven to 350 degrees F. While the oven warms, grease a 10- to 12-cup Bundt pan using baking spray or a mixture of butter and flour to ensure your cake releases easily.
- Mix the Batter: In a large bowl, combine the devil’s food cake mix, ¾ cup of canola or vegetable oil, ¾ cup of sour cream, and 3 large eggs. Mix until the batter is mostly smooth; some lumps are okay.
- Fold in Zucchini and Chocolate Chips: Gently fold in the shredded zucchini and 1 cup of the semi-sweet chocolate chips until well distributed through the batter.
- Transfer to Bundt Pan: Pour the batter into your prepared Bundt pan, smoothing the top with a spatula for an even bake.
- Bake: Place the pan in the preheated oven and bake for 45 to 55 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean.
- Cool the Cake: Once baked, let the cake cool in the pan for about 10 to 15 minutes. Then, carefully turn it out onto a wire rack to cool completely.
- Make the Ganache: Heat ¾ cup of heavy cream in a small saucepan until steaming. Pour it over the remaining 1 cup of chocolate chips in a mixing bowl, letting it sit for 1 to 2 minutes. Stir until smooth and glossy.
- Top the Cake: Allow the ganache to cool slightly before pouring it over your cooled cake, letting it drip beautifully down the sides. Allow it to set before slicing and serving.
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 prefer, you can refrigerate it for up to a week; just avoid letting it get too cold, as this can change the texture. For longer storage, slice and freeze portions in a well-sealed container or freezer bag for up to 3 months. To reheat, pop a slice in the microwave for about 15 seconds, just enough to take the chill off—it won’t be quite as moist as the fresh-baked version, but it will still be delicious!
Chef’s Helpful Tips
- When measuring shredded zucchini, press it lightly to remove excess moisture; this helps prevent the cake from becoming too wet.
- For the best results, use room temperature eggs and sour cream; they incorporate more beautifully into the batter.
- Keep an eye on baking time—ovens can vary! Check your cake a few minutes early to avoid overbaking.
- If you want a richer chocolate flavor, consider using dark cocoa powder in combination with the cake mix.
- Experiment with different types of chocolate chips; milk chocolate can add a different sweetness profile!
- Make it a day ahead for the best flavor; letting the cake sit overnight allows all the flavors to meld perfectly.
This Zucchini Chocolate Bundt Cake is not just delicious; it’s also an amazing way to sneak in some vegetables while indulging in a sweet treat. It’s perfect for sharing with friends and family, or enjoying quietly with a warm cup of coffee at your kitchen table. Feel free to personalize it—add nuts, spices, or your favorite flavors. The possibilities are endless! Enjoy the baking process and the delightful cake that follows.

Recipe FAQs
Can I use fresh zucchini directly, or should I squeeze out the moisture?
You can use fresh zucchini directly, but light pressing afterward helps extract excess moisture—this ensures a perfectly textured cake. You don’t want too much liquid for the right consistency.
Can I use a different kind of cake mix?
Absolutely! While the devil’s food cake mix contributes to the rich chocolate flavor, any chocolate cake mix will work just fine. Just make sure it’s the same size to keep the ratios correct.
What can I do if I don’t have a Bundt pan?
If you don’t have a Bundt pan, you can use a standard 9×13-inch baking dish instead. Just adjust the baking time, as it may slightly decrease. Check for doneness using the toothpick method!
Can I make this cake ahead of time?
Yes! You can prepare this cake a day or two in advance. Store it covered at room temperature, and it will keep its deliciousness while allowing flavors to develop further for even more taste.
