Triple Chocolate Zucchini Cake is just as delicious as it sounds. Chocolate, chocolate, chocolate, and zucchini. This is the best way to eat zucchini.

Chocolate Chip Zucchini Chocolate Cake. It’s a mouthful to say and the absolute best way to use up zucchini. The grated zucchini just melts into the cake giving it an incredibly moist and tender crumb. And the chocolate… well I’ve tripled it because who can resist? I can’t and all the chocolate fans in your life won’t be able to, either.

Family recipes are the best, right?! And this chocolate bundt cake recipe came from my Aunt Patty, who I am sure got it from my grandma. It is my favorite way to use up zucchini and I’ve been making it for years.

The cake is the same as it’s always been, and I just added my favorite frosting and chocolate chips because triple the chocolate just seemed the right thing to do. I am sure it will continue to be passed down from generation to generation because it is that delicious.

My entire reasoning ever for planting zucchini in my garden is to make this triple chocolate cake. Back when we sold our house, I was left without a garden, but thank goodness for friends. One of my friends Erin (she blogs over at Dinner, Dishes and Dessert) was so nice to share her garden zucchini with me at the time so I didn’t have to miss out.

That was a while ago now and I’m still making this cake. You don’t need to wait until summer – with zucchini abundantly available year-round, you can make it whenever you need a serious dose of chocolate.

I seriously love zucchini. Whether in bread, pasta, enchiladas, fried, floured, really any way you can prepare it, I love it! But in all honesty, I am a sugar freak, so adding chocolate to one of my favorite vegetables is like a dream come true.

Recipe Highlights

  • This cake is all about the chocolate, but the real secret is the zucchini. It adds so much moisture. No dry cake here – just forkfuls of rich chocolaty goodness.
  • The tender and moist cake is topped with a simple three-ingredient chocolate glaze that is the perfect canvas for a sprinkling of mini chocolate chips.
  • This is a cake to impress – perfect for gifting, for sharing, or for keeping all to yourself.

This Triple Chocolate Zucchini Cake is so easy to make, gorgeous and everyone who has ever tried it loves it.
