Chocolate Zucchini Cake Ingredients
For the Cake
• All-purpose flour – Provides structure and texture. Measure accurately using the spoon-and-level method to prevent dry cake.
• Unsweetened cocoa powder – Adds rich chocolate flavor. Natural cocoa powder is recommended, not Dutch process.
• Light brown sugar – Provides sweetness and moisture.
• Fine sea salt – Balances sweetness and enhances flavor.
• Baking soda – Acts as a leavening agent, helping the cake rise.
• Unsalted butter – Contributes richness and moisture. Can be replaced with more oil or yogurt if desired.
• Vegetable oil – Adds moisture and a tender crumb. Can substitute with melted coconut oil or other neutral oil.
• Full-fat sour cream or plain yogurt – Keeps the cake moist and adds tangy flavor. Can use Greek yogurt as a substitute.
• Eggs and egg yolk – Provides binding and structure. Ensure they are at room temperature for better emulsification.
• Vanilla extract – Enhances overall flavor.
• Shredded zucchini – Adds moisture and a hidden vegetable element. Squeeze out excess water to avoid a gummy texture.
• Semisweet chocolate chips – Gives bursts of chocolate flavor throughout the cake. Other varieties, like milk or white chocolate, can be used based on preference.

Step‑by‑Step Instructions for Chocolate Zucchini Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (or 325°F if using a glass pan) to ensure your Chocolate Zucchini Cake bakes evenly. While the oven warms up, line an 8x8 inch baking pan with parchment paper, allowing some overhang for easy removal. Lightly spray the lined pan with nonstick spray to prevent sticking later on.
Step 2: Whisk Wet Ingredients
In a small bowl, combine the melted unsalted butter, vegetable oil, full-fat sour cream (or yogurt), eggs, and vanilla extract. Whisk these ingredients together until they form a smooth mixture. This step takes about 2-3 minutes and helps to ensure an even distribution of flavors throughout your cake.
Step 3: Mix Dry Ingredients
In a large mixing bowl, sift together the all-purpose flour, unsweetened cocoa powder, light brown sugar, fine sea salt, and baking soda. This mixture should be well combined and free of lumps, creating a light and airy base for your Chocolate Zucchini Cake. Use a whisk to mix it for about 2 minutes to ensure everything is evenly distributed.
Step 4: Combine Wet and Dry Mixtures
Make a well in the center of your dry ingredients and pour in the whisked wet mixture. Gently stir the ingredients together until just combined—beware not to overmix, as this will keep your cake tender and moist. A few flour streaks are perfectly fine; you want a thick batter consistency.
Step 5: Fold in Zucchini and Chocolate Chips
Carefully fold in the shredded zucchini and semisweet chocolate chips into the batter. Use a spatula to ensure they’re evenly dispersed without overworking the batter. You'll notice flecks of green from the zucchini as it blends into the rich chocolate mixture, enhancing the cake's moisture and flavor.
Step 6: Bake the Cake
Pour the batter into your prepared baking pan, smoothing the top if necessary. Place the pan in your preheated oven and bake for about 30 minutes, or until a toothpick inserted in the center comes out clean. You'll know the cake is ready when it has risen slightly and the edges start to pull away from the pan.
Step 7: Prepare the Glaze
While your Chocolate Zucchini Cake cools, whisk together the powdered sugar and a splash of milk in a small bowl until smooth. Adjust the milk quantity to achieve your desired glaze consistency. This simple glaze adds a lovely finishing touch to your cake, enhancing its sweetness and visual appeal.
Step 8: Drizzle and Serve
Once the cake has cooled completely in the pan, remove it using the parchment overhang and place it on a wire rack. Drizzle the prepared glaze over the top of the cake, letting it cascade down the sides. Slice into squares and serve your delicious Chocolate Zucchini Cake at room temperature or slightly warm for an irresistible treat!
Expert Tips for Chocolate Zucchini Cake
Moisture Control: Remove excess water from the zucchini before adding it to the batter. This step prevents a gummy texture in your chocolate zucchini cake.
Accurate Measurements: Weigh your cocoa powder and flour if possible. Overmeasuring can lead to a dry cake, so use the spoon-and-level method for best results.
Pan Temperature: Remember to lower the oven temperature to 325°F when using a glass pan. This helps avoid over-baking and ensures a perfectly fudgy texture.
Gentle Mixing: When combining wet and dry ingredients, mix until just combined. This will keep your cake tender and moist, perfect for chocolate lovers.
Flavor Variations: Feel free to swap out ingredients, like using half whole wheat flour or trying different chocolate chips, to personalize your chocolate zucchini cake to your taste!

Chocolate Zucchini Cake Recipe FAQs
What is the secret to super moist cake?
To achieve a super moist Chocolate Zucchini Cake, the key lies in balancing the ingredients and techniques. Use fresh, finely shredded zucchini, and be sure to squeeze out any excess moisture to avoid a gummy texture. Incorporating moist ingredients like sour cream or yogurt will also help keep the cake deliciously rich. Avoid overmixing the batter, as this can lead to a dense cake. Finally, monitor your baking time closely to prevent dryness.
Do you peel zucchini for zucchini cake?
No, there is no need to peel the zucchini for your Chocolate Zucchini Cake! The skin adds extra nutrition and beautiful flecks of green in your cake, while also providing moisture. Just wash and finely shred the zucchini before adding it to your batter for the best results. This way, you’ll enjoy all the benefits without sacrificing the delightful chocolate flavor.
Should zucchini cake be refrigerated?
While it’s not necessary to refrigerate your Chocolate Zucchini Cake, doing so can extend its freshness. If you choose to refrigerate it, ensure it’s stored in an airtight container to prevent it from drying out, and enjoy it within a week. For room temperature storage, 4 days is ideal. Whichever you choose, this moist cake is sure to delight your taste buds!
Can I freeze Chocolate Zucchini Cake?
Absolutely! To freeze your delicious Chocolate Zucchini Cake, start by slicing it into individual portions. Wrap each slice tightly in plastic wrap, then place them in a ziplock bag or aluminum foil for extra protection. This method helps to preserve the cake's moistness. You can freeze it for up to 2 months. When you're ready to enjoy a slice, simply thaw it at room temperature for about 30 minutes, or pop it in the microwave for 10-15 seconds to warm it up!
What is the best frosting for zucchini cake?
For an irresistible pairing, try a cream cheese frosting—it complements the richness of the Chocolate Zucchini Cake beautifully. However, you can also opt for a simple glaze made with powdered sugar and milk for a lighter touch, as mentioned in this recipe. If you want something decadent, a chocolate ganache could be delightful as well. The choice depends on your frosting preference—whether you like it rich or light!
What if my cake turns out too dense?
If your Chocolate Zucchini Cake ends up too dense, it might be due to overmixing the batter or using too much flour. Stir the wet and dry ingredients until just combined, and consider weighing your flour for accuracy. Also, make sure to use fresh baking soda for proper leavening. Adding in extra moisture—perhaps a touch more sour cream or a bit of oil—might help your cake achieve that perfect fudgy texture!
