Ingredients You’ll Need
- 1 (15.25-ounce) box devil’s food cake mix: This forms the base of our cake, contributing to its moistness and rich flavor. Duncan Hines is a solid choice for that chocolatey goodness.
- ¾ cup canola or vegetable oil: Adds moisture to the cake, ensuring it remains tender and fluffy.
- ¾ cup sour cream: This not only contributes to the cake’s moisture but also adds a delightful tang that balances out the sweetness.
- 3 large eggs: Essential for binding the ingredients together and providing structure in the cake.
- 2 cups shredded zucchini (about 2 medium): The star ingredient here! It keeps the cake moist and adds a subtle, fresh flavor that complements the chocolate beautifully.
- 2 cups semi-sweet chocolate chips, divided: These little gems of chocolate create delicious pockets of sweetness throughout the cake. Use high-quality chips for the best flavor.
- ¾ cup heavy cream: This will be used to make a decadent ganache that takes our already delightful cake to the next level.
How to Make Zucchini Chocolate Bundt Cake
- Preheat your oven: Start by setting your oven to 350 degrees F. The perfect temperature for baking our cake to a luscious finish!
- Prepare the Bundt pan: Grease a 10- to 12-cup Bundt pan with baking spray or butter and dust it with flour to prevent sticking.
- Mix the batter: In a large bowl, combine the cake mix, ¾ cup canola or vegetable oil, ¾ cup sour cream, and 3 large eggs. Whisk until the batter is mostly smooth, but don’t worry about a few lumps—this is a cake, after all!
- Fold in the zucchini and chocolate: Gently fold in 2 cups of shredded zucchini and 1 cup of semi-sweet chocolate chips. The batter will be thick and luxurious.
- Pour and smooth: Transfer the batter into your prepared Bundt pan, smoothing the top with a spatula for an even bake.
- Bake to perfection: Pop your cake into the preheated oven for 45 to 55 minutes, or until a toothpick inserted in the center comes out clean. You’ll know it’s ready when you start smelling that heavenly aroma wafting through your kitchen!
- Cool the cake: Let the cake cool in the pan for about 10 to 15 minutes. Then, gently turn it out onto a wire rack to cool completely. Resist the urge to slice into it right away!
- Make the ganache: While the cake cools, heat ¾ cup heavy cream in a saucepan until steaming (but not boiling). Pour it over the remaining 1 cup of semi-sweet chocolate chips in a bowl. Allow it to sit for 1 to 2 minutes, then stir until smooth and glossy.
- Top the cake: Once the cake has completely cooled, drizzle the chocolate ganache generously over the top. Let it set for a bit before slicing, allowing the beauty of the ganache to shine through.
Storing & Reheating
To keep your Zucchini Chocolate Bundt Cake fresh, store it at room temperature in an airtight container for up to 3 days. If you need a longer shelf life, refrigerate it for about a week. For freezing, wrap the cake tightly in plastic wrap, followed by aluminum foil, and store it in the freezer for up to 3 months. When you’re ready to enjoy it again, simply thaw it in the fridge overnight. While the texture may change slightly after freezing, it’ll still taste divine; a quick zap in the microwave for 10-15 seconds can help refresh it!
Chef’s Helpful Tips
- Don’t skip the cooling step: Allowing the cake to cool properly ensures that it maintains its structure when you remove it from the pan.
- Use fresh zucchini: Opt for fresh zucchini as they have a higher moisture content that helps the cake stay moist.
- Be gentle when folding: When adding zucchini and chocolate chips to the batter, fold gently to avoid overmixing, which could make the cake tough.
- Check for doneness: Every oven is different! Use a toothpick to check for doneness and start checking a few minutes before the recommended baking time.
- Play with toppings: Feel free to sprinkle some extra chocolate chips on top of the ganache while it’s still warm for an extra-cute presentation.
The Zucchini Chocolate Bundt Cake is not just a dessert; it’s an experience that tempts the palate and brings joy with every bite. Whether you’re indulging solo or sharing with friends and family, its moist layers coupled with rich chocolate flavor are sure to impress. Don’t hesitate to experiment with your favorite mix-ins or toppings. Enjoy flavors that speak to you, and have fun with this versatile recipe!

Recipe FAQs
Can I use other types of cake mix?
Absolutely! While devil’s food cake mix gives a rich flavor, you can experiment with other chocolate or even vanilla cake mixes. The key is to keep the overall batter consistency similar.
How can I make this cake even more chocolatey?
If you’re a true chocolate lover, you can add extra chocolate chips or cocoa powder to the batter. For an extra layer of richness, consider mixing some finely chopped chocolate bars into the batter.
What if I have leftover cake? Can it be frozen?
Yes, it can! Make sure it’s fully cooled, then wrap it tightly in plastic wrap and aluminum foil before freezing. It should maintain its quality for up to 3 months.
How do I ensure my cake doesn’t stick to the Bundt pan?
Proper greasing is crucial. Don’t skip this step! Either use non-stick baking spray or generously brush with butter followed by dusting with flour to create a protective barrier that will help the cake slide out effortlessly.
