Why we Love this Cake
How do you feel about chocolate covered veggies? Sure we love eating zucchini in savory dinner recipes, but I absolutely love using zucchini in chocolate baked goods. The shredded zucchini adds so much moisture and makes chocolate desserts so fudgy and delicious.
I changed up the ingredients in this chocolate zucchini cake because I wanted a fluffier zucchini cake. There are 2 whole cups of shredded zucchini in this cake giving it such a decadent and moist texture. It has such a great chocolate flavor.
A creamy marshmallow cream cheese frosting makes this chocolate chip zucchini cake so rich and delicious. You are going to love it!
This chocolate zucchini cake with chocolate chips calls for ingredients from your pantry and fresh summer zucchini. The added sour cream provides extra moisture, so the cake bakes up fluffy yet moist.
For the Chocolate Cake
- Butter – Unsalted and softened.
- Sugars – A mixture of granulated sugar and brown sugar sweetens the cake.
- Sour Cream – Gives the cake a moist fluffy texture.
- Egg – Binds everything together and adds moisture to the cake batter.
- Zucchini – 2 small-medium sized and shredded using a small grater.
- Flour – Adds structure to the cake batter.

- Vanilla Extract & Salt – Adds flavor and balances out the sweetness.
- Miniature Chocolate Chips – Adding chocolate chips in the batter and on top of the finished cake gives it so much chocolate flavor.
