How to Make Chocolate Zucchini Cake (Step-by-Step)
This delightful cake is simple to make and full of flavor!
Step 1: Prep Your Zucchini
First, wash and trim the ends of your zucchini. Grate it finely using a box grater. Squeeze out excess moisture using a clean kitchen towel to prevent a soggy cake.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt until well combined. The aroma of the cocoa will make your kitchen smell heavenly.
Step 3: Cream the Sugars and Eggs
In a large mixing bowl, beat together the granulated sugar, brown sugar, and eggs using an electric mixer. Whisk until the mixture is pale and fluffy-this should take about 2 minutes. Add the vegetable oil and vanilla extract, then mix until everything is combined.
Step 4: Combine Wet and Dry
Gradually add the dry ingredients to the wet mixture, folding gently with a spatula. Be careful not to over-mix; you'll want a smooth batter, but a few lumps are okay.
Step 5: Add Zucchini and Chocolate Chips
Fold in the finely grated zucchini and semi-sweet chocolate chips. The chocolate chips will melt slightly in the oven, creating decadent pockets of chocolate throughout the cake.
Step 6: Bake
Pour the batter into a greased 9-inch round cake pan or a lined loaf pan. Bake in a preheated oven at 350°F (175°C) for about 25 to 30 minutes, or until a toothpick inserted in the center comes out clean with a few moist crumbs.
Step 7: Cool and Serve
Once baked, allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. It can be served as is or dusted with powdered sugar for a festive touch.

Common Mistakes to Avoid
- Skipping the Zucchini Squeeze: Neglecting to remove excess moisture can lead to a dense, soggy cake.
- Overmixing the Batter: This can cause the cake to become tough. Mix just until the dry ingredients are incorporated.
- Underbaking: Always check for doneness with a toothpick. A slightly wet toothpick indicates a moist, perfect cake, while a wet one means it needs more time.
Tips and Tricks for Success
- For an even richer flavor, try adding a teaspoon of espresso powder to the dry ingredients.
- If you have it, add chopped walnuts or pecans for a lovely texture.
- This cake also freezes beautifully-just wrap it tightly in plastic wrap and foil, and it can last for up to three months.
Variations
- Use almond flour or gluten-free all-purpose flour for a gluten-free version.
- Substitute honey or maple syrup for granulated sugar for a natural sweetener.
- Add spices such as cinnamon or nutmeg for an extra flavor boost.
- Incorporate shredded carrots for a delicious carrot-zucchini fusion cake.
How to Serve
- Dust with powdered sugar for a festive touch.
- Pair with a scoop of vanilla ice cream for extra indulgence.
- Serve warm with a drizzle of chocolate sauce.
- Top with fresh berries for a refreshing contrast.

Make Ahead and Storage
- Make Ahead: Prepare the batter a day in advance and refrigerate until ready to bake.
- Storage: Store leftovers in an airtight container at room temperature for up to 3 days or in the fridge for up to a week.
- Reheating: Warm individual slices in the microwave for a few seconds before serving for a fresh-baked taste.
- Freezing: Wrap tightly in plastic wrap and foil for up to three months.
