It’s the perfect way to utilize your garden zucchini—bake it repeatedly!

I initially created this cake for a blogger group focused on squash cooking. You might remember that my husband avoids zucchini at all costs. I hoped that a bit of culinary magic could change his mind!

However, three cups of shredded zucchini were a hard disguise, even with cocoa powder and chocolate chips added. There were tiny green spots mixed in with the rich chocolate batter. The big question was, would he eat the Chocolate Zucchini Bundt Cake? Keep reading to find out!

Chocolate Bundt Cake

The first time I baked this cake, Bill came home and noticed it instantly on the counter. He was excited to learn it was for us!

However, as he examined his piece post-dinner, he tried to pick out any visible “green stuff.” Foiled again! But he admitted he enjoyed the cake before I revealed the secret ingredient. He even suggested leaving the zucchini out next time! What a surprise.

Now, fast forward six years—when I made it again, I must’ve grated the zucchini finer as he didn’t say a word while polishing off his plate! I shared some with friends, and they were amazed at how moist and flavorful it was once I assured them they couldn’t taste the zucchini.

Expert Tips

If you’re a zucchini fan, you’ll find this cake to be truly marvelous.

While it doesn’t pack the intense chocolate flavor of some other cakes, it is incredibly moist and tender. My friends unanimously praised this chocolate zucchini Bundt cake!
Unlike zucchini bread, the grated zucchini does not need to be squeezed dry; the added moisture is needed for baking.
Pro Tip: If your kids (or spouse) shy away from zucchini cake, finely grate the zucchini so it isn’t as visible.
Pro Tip: This recipe utilizes both baking soda and baking powder. Check the expiration date of your baking powder; if it’s close to expiring, consider purchasing a fresh container for best results.
A classic Bundt pan is ideal for this recipe since the chocolate chips tend to stick. Make sure to prep your pan well.
Let the cake cool on a wire rack for about 10-15 minutes before inverting onto a cooling rack to avoid breakage.
To flip the cake, I usually place the cooling rack upside down on top of the cake and flip both over together.
Give the pan a gentle jiggle to loosen the cake before removing. Use hot pads during this process!

Frequently Asked Questions

What is Bundt Cake?

A Bundt cake is named after the pan it’s baked in. This unique tube pan creates a cake with a hole in the center. Bundt pans can vary from simple designs to intricate shapes. Even non-stick pans need proper greasing to ensure a successful release!

How Long Does a Bundt Cake Bake?

Bundt cake batter is denser than typical cake batter to maintain its shape. While a layer cake might bake in 25-30 minutes, a Bundt cake generally takes over an hour. Always check doneness with a toothpick in the center of the cake.

What Does Zucchini Add to a Cake?

Simply put, moisture! Zucchini is mostly water, which releases during baking and keeps your cake wonderfully moist. You may see a few small green specks, but there’s no change in taste!
