Chocolate Chip Zucchini Cake

This Chocolate Zucchini Cake Recipe is outrageous! It is incredibly moist and has a triple chocolate combination. Chocolate cake, chocolate chips and chocolate ganache on top!

Ingredient Substitutions

If you do not have sour cream, yogurt or buttermilk on hand you can add 1/2 Tablespoon of vinegar to 1/2 cup of milk to substitute the buttermilk.

Quick tip: My favorite tool for stirring the buttermilk on the stove to keep it from scorching is this sauce wisk.

You can also sub unsweetened applesauce for vegetable oil if desired.

Preparing the Zucchini

If you have a large zucchini with lots of large seeds you will want to use a Zucchini corer to remove the seeds. For fast shredding of my zucchini, I used my Cuisinart Food Processor.

Once you have the zucchini prepared you can fold it into your batter with the chocolate chips. Then you’re ready to bake it!

Adding chocolate frosting

Adding the Chocolate Ganache Frosting

Once your triple chocolate zucchini cake is finished baking, allow it to cool before adding the frosting.

Then, once you’ve made the frosting and it’s still warm, pour it evenly over the cake. 30 minutes later it will be set and ready to serve!

This chocolate chip zucchini is amazing! I’m not sure if I can say that it’s healthy since it has triple chocolate, but it’s definitely kid-friendly!

Make sure to serve it with a nice cold glass of chocolate milk and enjoy! Don’t forget to check out our other zucchini recipes below as well.
