Ingredients
For the Cake

- 1 teaspoon vinegar
- 3 cups oat flour
- 2/3 cup cocoa powder
- 2 tablespoons arrowroot powder
- 1 teaspoon baking soda

How to Make Chocolate Zucchini Cake
Step 1: Preheat the Oven
Preheat the oven to 180C/350F. Grease two 8-inch cake pans and set them aside.
Step 2: Prepare Buttermilk Mixture
In a bowl, add the milk and vinegar. Whisk them together and let it sit until it curdles. This will create a homemade buttermilk that adds moisture to your cake.
Step 3: Mix Dry Ingredients
In a large mixing bowl, combine the oat flour, cocoa powder, arrowroot powder, baking soda, and baking powder. Mix well to ensure all dry ingredients are evenly distributed.
Step 4: Combine Wet Ingredients
In another bowl, whisk together the curdled milk mixture, brown sugar, and unsweetened applesauce until smooth.
Step 5: Combine Dry and Wet Ingredients
Pour the wet mixture into the dry ingredients. Stir until just combined. Gently fold in the shredded zucchini until evenly distributed throughout the batter.
Step 6: Bake the Cake
Distribute the batter evenly between the two prepared cake pans. Bake in the preheated oven for about 35-40 minutes or until a skewer inserted into the center comes out clean.
Step 7: Cool and Frost
Once baked, remove the cakes from the oven and allow them to cool completely in their pans. After cooling, frost each layer with chocolate frosting before stacking them together. Slice as needed and serve!

How to Perfect Chocolate Zucchini Cake

- Use fresh zucchini: Make sure the zucchini is fresh and well-shredded to maintain moisture without adding excess water.
- Measure ingredients accurately: Use precise measurements, especially for dry ingredients, to achieve the desired texture.
- Don’t overmix the batter: Mix until just combined to keep the cake tender and avoid a dense texture.
- Test for doneness: Use a toothpick or skewer; it should come out clean when inserted in the center.
- Cool completely before frosting: Allowing the cake to cool prevents melting and ensures neat frosting application.
- Store properly: Keep leftovers covered at room temperature or in the fridge for freshness.
Best Side Dishes for Chocolate Zucchini Cake
Pairing your Chocolate Zucchini Cake with side dishes can create a well-rounded dessert table. Here are some great options to consider:
- Fresh Berries – A medley of strawberries, blueberries, and raspberries adds freshness and balance to the sweet cake.

- Chocolate Dipped Fruits – Offer fruits like bananas or strawberries dipped in chocolate to complement your cake’s flavors.
- Cream Cheese Frosting – Serve alongside extra frosting made from cream cheese for those who love an indulgent treat.
- Coffee or Espresso – A cup of coffee enhances chocolate flavors and makes for an elegant pairing.
- Pecan Pie Bars – These sweet bars add crunch and contrast against the softness of the cake.
- Coconut Whipped Cream – For a dairy-free option, coconut whipped cream brings tropical flair to your dessert spread.
Common Mistakes to Avoid
Baking can be tricky, especially with a unique recipe like Chocolate Zucchini Cake. Here are some common mistakes and how to avoid them.
- Using wet zucchini: Always make sure to squeeze out excess moisture from the shredded zucchini. This prevents the cake from becoming too soggy.
- Ignoring the curdling process: The milk and vinegar mixture must sit long enough to curdle. Rushing this step can affect the cake’s texture.
- Overmixing the batter: Gently fold the wet and dry ingredients together. Overmixing can lead to a dense cake instead of a light and fluffy one.
- Not checking for doneness: Always use a skewer or toothpick to check if the cake is fully baked. This ensures a perfectly cooked Chocolate Zucchini Cake.
- Skipping the cooling time: Allow the cakes to cool completely before frosting. Frosting warm cakes can cause the frosting to melt and slide off.
