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, but it’s the absolute best way to use up zucchini. The grated zucchini melts into the cake, making it incredibly moist. 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?! 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 seemed the right thing to do. I am sure it will continue to be passed down from generation to generation because it is delicious.

The entire reason I planted zucchini in my garden is to make this triple chocolate cake. You don’t need to wait until summerโ€”zucchini is abundantly available year-roundโ€”to make it.

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.

Why Our Family Loves This Recipe

This cake is all about the chocolate, but the real secret is the zucchini. It adds so much moistureโ€”there is no dry cake hereโ€”just forkfuls of rich chocolaty goodness.
