• Ground Cinnamon – Adds a warm, inviting note that complements the chocolate beautifully.
• Unsalted Butter – Brings moisture and richness; make sure it’s softened for easy mixing.

• Large Eggs – Binds the ingredients together; large eggs yield the best texture.
• Vanilla Extract – Enhances the flavor; opt for pure vanilla extract for the best results.

Step‑by‑Step Instructions for Chocolate Zucchini Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare a 9×13 inch baking pan by greasing it with butter or vegetable oil, and dusting it with flour, or line it with parchment paper. This will ensure your Chocolate Zucchini Cake releases easily after baking, allowing for a clean serve.
Step 2: Sift the Dry Ingredients
In a medium mixing bowl, sift together 1 ¾ cups of all-purpose flour, ¾ cup of unsweetened cocoa powder, 1 teaspoon of baking soda, 1 teaspoon of baking powder, ½ teaspoon of salt, and 1 teaspoon of ground cinnamon. This step is important as it removes lumps and evenly distributes the leavening agents, which are crucial for achieving a soft texture in your cake. Set the bowl aside for later.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, combine ½ cup of softened unsalted butter, ½ cup of vegetable oil, and 1 ¾ cups of granulated sugar. Using an electric mixer, beat the mixture on medium speed for about 3-4 minutes until it becomes light and fluffy. This process incorporates air, helping your Chocolate Zucchini Cake rise beautifully.
Step 4: Add Eggs and Vanilla
Next, crack in 2 large eggs, adding them one at a time, mixing well after each addition to ensure a smooth batter. Stir in 2 teaspoons of pure vanilla extract until combined. The eggs will bind the ingredients and provide richness, while the vanilla enhances the overall flavor of your cake.
Step 5: Combine Dry Ingredients with Buttermilk
Gradually mix in your previously sifted dry ingredients, alternating with 1 cup of buttermilk, beginning and ending with the flour mixture. Stir just until everything is combined; over-mixing can lead to a dense cake. When you see no streaks of flour, your batter is ready for the next step.
Step 6: Fold in Zucchini and Chocolate Chips
Gently fold in 1 ½ cups of grated zucchini and 1 cup of semi-sweet chocolate chips using a spatula. Be careful not to over-mix; you want to maintain that light and airy texture in your Chocolate Zucchini Cake. The grated zucchini will blend seamlessly into the batter, adding moisture without any distinct flavor.
Step 7: Pour and Spread the Batter
Pour the luscious batter into your prepared baking pan, using a spatula to spread it evenly across the surface. This step ensures even baking, allowing every bite of your Chocolate Zucchini Cake to be just as delightful as the last.
Step 8: Bake the Cake
Place the baking pan in the preheated oven and bake for 45-50 minutes. Keep an eye on the cake, and perform a toothpick test around the 45-minute mark; it should come out clean or with a few moist crumbs. This signals that your Chocolate Zucchini Cake is ready to be taken out.
Step 9: Cool the Cake
Once baked, remove the pan from the oven and let it cool in the pan for about 10 minutes. After that, carefully transfer the cake to a wire rack to cool completely. Allowing it to cool properly will help maintain its structure and prevent it from becoming too moist at the bottom.
Step 10: Serve and Enjoy
When the cake is completely cool, slice it into generous pieces. You can enjoy it as is or dress it up with a light dusting of powdered sugar or a dollop of whipped cream for an extra treat. Your Chocolate Zucchini Cake is now ready to impress friends and family, offering a tasty twist with hidden veggies!
