Chocolate Zucchini Bundt Cake
Chocolate zucchini bundt cake gives you a rich cocoa dessert that stays moist for days, thanks to simple shredded zucchini.
This is the kind of from-scratch cake I make when I want something chocolatey without buying special ingredients. The zucchini melts into the crumb, the sour cream adds tenderness, and the chocolate chips give every slice little pockets of sweetness.
Why You’ll Love This Recipe
- Moist texture: Shredded zucchini keeps the cake soft without making it taste like vegetables.
- Deep chocolate flavor: Cocoa powder and chocolate chips make each slice rich and satisfying.
- Simple pantry baking: You only need basic baking staples and one fresh zucchini.
- Small batch size: This version makes a modest Bundt cake that serves 4 generous slices.
Fabian’s Budget Tip: Use zucchini when it is in season or grate and freeze extra zucchini in 1 cup portions. Thaw it, squeeze it lightly, and use it for cake without buying anything new.
Ingredients (Serves 4)
- 1 cup shredded zucchini, lightly squeezed if very watery (120 g)
- 1 cup all purpose flour (125 g)
- 1 quarter cup unsweetened cocoa powder (25 g)
- 3 quarters cup granulated sugar (150 g)
- 2 large eggs
- 1 third cup sour cream (80 g)
- 1 quarter cup vegetable oil (60 ml)
- 1 half cup chocolate chips (85 g)
- 1 teaspoon vanilla extract (5 ml)
- 1 half teaspoon baking soda (3 g)
- Extra vegetable oil or baking spray for greasing the Bundt pan
Step-by-Step Instructions
1. Prepare the Pan and Oven
Heat the oven to 350°F (175°C). Grease a 6 cup Bundt pan very well, getting into every curve. A well-greased pan helps the cake release with a clean, glossy edge.
2. Mix the Dry Ingredients
Add the all purpose flour, cocoa powder, sugar, and baking soda to a large bowl. Whisk until the cocoa looks evenly blended and no pale streaks of flour remain.
3. Stir the Wet Ingredients
In a second bowl, whisk the eggs, sour cream, vegetable oil, and vanilla extract. The mixture should look smooth, shiny, and lightly thick.
4. Combine the Batter
Pour the wet mixture into the dry mixture. Stir just until the batter comes together. It will look thick and dark, like brownie batter. Stop mixing once you no longer see dry flour.
5. Fold in the Zucchini and Chocolate Chips
Add the shredded zucchini and chocolate chips. Fold gently with a spatula until the green zucchini threads disappear into the chocolate batter and the chips look evenly scattered.
6. Fill the Bundt Pan
Spoon the batter into the greased Bundt pan. Smooth the top and tap the pan once or twice on the counter to settle the batter into the ridges.
7. Bake Until Set
Bake for 35 to 42 minutes, or until the cake smells deeply chocolatey and a skewer inserted into the center comes out clean or with a few moist crumbs. If you see wet batter, give it a few more minutes.
8. Cool and Release
Let the cake cool in the pan for 15 minutes. The edges should pull back slightly from the pan. Turn it onto a plate and let it cool before slicing so the crumb stays tender and neat.15
Expert Troubleshooting and FAQs
Can you taste the zucchini?
No. The zucchini adds moisture, but the flavor blends into the cocoa and vanilla. Most people will not know it is there unless you tell them.
Should I peel the zucchini first?
No. The peel is tender and adds tiny green flecks. If you want a smoother look, use the fine side of a box grater.
Why did my cake turn out dry?
Dry cake usually comes from too much flour or too much baking time. Spoon the flour into the measuring cup, level it gently, and check the cake as soon as your kitchen smells like warm chocolate.
Can I use Greek yogurt instead of sour cream?
Yes. Plain full-fat Greek yogurt works well in the same amount. It gives a similar tang and soft crumb.
What if I only have a larger Bundt pan?
You can use it, but the cake will be shorter. Start checking around 28 minutes because the thinner batter layer may bake faster.
How should I store leftovers?
Cover the cake tightly and store it at room temperature for up to 2 days. For longer storage, refrigerate it for up to 5 days. Let slices sit at room temperature for a few minutes before serving for the best texture.
