Have you ever tried chocolate zucchini cake? You don’t taste the zucchini at all, and instead you end up with the most delicious chocolate cake that’s moist with a soft, dense cake crumb.
Growing up one of my favorite recipes was my Mom’s simple chocolate cake. It was moist, not too rich, topped with chocolate buttercream, and perfect for children. She’d decorate it with candies for our birthdays, and I was always thrilled when she made it.
So when she told me one afternoon that she was making chocolate zucchini cake – I wasn’t impressed. The idea of vegetables in cake seemed wrong, and I felt she was ruining my favorite recipe.
But after tasting the chocolate zucchini cake, I had to swallow my words (along with some cake). Because chocolate zucchini cake is delicious. So moist & full of chocolate goodness. I was converted.
How to Make Chocolate Zucchini Cake
For today’s chocolate zucchini cake we start by beating together the oil, sugar, eggs, vanilla, sour cream, and shredded zucchini. Then we’ll whisk together the dry ingredients, then beat them into the mixture. Easy as that.
For the shredded zucchini, if you find there’s excess liquid you can gently soak it up with a paper towel. Just make sure it isn’t dry when adding to the cake.
Then after everything’s mixed together, then the batter is poured into a 9×13 inch pan and it’s ready to bake.
For the Chocolate Buttercream Frosting
The chocolate zucchini cake itself is so flavorful. But for an extra dose of chocolate, we’re topping it with chocolate buttercream frosting. It’s a simple frosting recipe made with cocoa powder – however I like to add a little cream cheese to cut the sweetness. If you don’t have cream cheese on hand, you can easily substitute it with more butter too.
This chocolate zucchini cake is the perfect recipe if you like a chocolate cake that’s moist, fudgy, and easy to make. I hope you love the recipe as much as I do!
