Moist Chocolate Zucchini Cake

This chocolate zucchini cake is so moist and chocolatey you won’t believe it is made with zucchini. And, the frosting is chocolate cream cheese perfection!

This cake is my answer for all the zucchini squash sitting on my counter! It is the most moist and rich cake, and adding zucchini to it makes it pretty much healthy, right?
Ok, not at all, but it sure is a good excuse for eating multiple pieces. Shhhhh…don’t judge!

I keep seeing people post about all their excess zucchinis in our neighborhood Facebook group. It needs to be put into this cake or our chocolate chip zucchini banana bread. Or if you are craving savory, try our BBQ zucchini nachos or our Mexican zucchini boats! Zucchini is so versatile!

(Mom, you are seriously the cutest and please oh please let my hair turn out like your’s)
This chocolate zucchini snack cake is actually the perfect picture of my life. Well, it’s the perfect picture of how my life goes. I go to Idaho and tell my mom I made the MOST DELICIOUS dark chocolate zucchini bundt cake in the history of the world.
Mom applauds me and gives me all sorts of praise.
Mom makes an even better chocolate zucchini cake and serves it for Sunday dinner and I beg her for the recipe.
I’d get all whomp, whomp on you, but I actually love when she beats me in the kitchen and proves herself to be the true cook in the family. Her food is always the best.
