Do you have neighbors been leaving bags of zucchinis at your doorstep? This rich double Chocolate Zucchini Bundt Cake with chocolate chips will be the tastiest treat you’ll make with your summer squash supply!

Adding zucchini to baked goods works all sorts of magic! Just like with zucchini bread, the addition of grated zucchini adds moisture, not to mention a smidgen of nutrition! This Chocolate Zucchini Cake was a hit across the board!

Chocolate Zucchini Bundt Cake

Originally, I made this cake for a blogger group that was cooking with squash! You may recall that the hubby avoids zucchini like the plague. I was hopeful that a bit of smoke and mirrors could change all that.

But three cups of shredded zucchini was hard to disguise even with the addition of cocoa powder and chocolate chips. There were minuscule telltale spots of green interspersed amongst the rich chocolate base. Would he or wouldn’t he eat this Chocolate Zucchini Bundt Cake? Read on to find out. But first, some frequently asked questions. 

What is Bundt Cake?

A Bundt cake is named after the pan in which it’s baked. Like an angel food cake pan, it’s a tube pan that will bake up with a hole in the center. Bundt pans range from a basic design to very intricate. The non-stick coating can wear off over time, so I tend to use a classic Bundt pan unless I have a very new model. And even a non-stick Bundt pan should be prepped properly for a proper release.

How Long Does a Bundt Cake Bake?

To keep its shape, a Bundt cake batter is thicker than a typical cake batter so that it bakes up dense and sturdy.  A layer cake may take only 25-30 minutes to bake, but a Bundt cake may take over an hour. Since all ovens bake differently, it’s imperative to use a toothpick to check if the cake is done. A toothpick inserted into the middle of the cake should come out clean. Check a number of spots to be sure.

No Ordinary Chocolate Bundt Cake

The first time I baked this chocolate zucchini cake, Bill spotted it on the kitchen counter after arriving home from work. He was most pleased to learn it was designated for home.

I saw him examining his slice after dinner, then taking his fork to pull out any visible “green stuff.” Foiled again! But he did admit he liked the cake before I revealed the secret ingredient. He suggested that I leave out the zucchini next time! Sheesh.

Fast forward 6 years, and I gave it another shot. I must have grated the zucchini even finer, as he never said a word, just cleaned his plate! I shared some slices with a few girlfriends. The first asked if you could taste the zucchini, and after I assured her you couldn’t, she dived right in. After her first bite, she wasn’t shy to say how much she loved it, and how it was so very moist and tasty!

Tips for Making a Chocolate Zucchini Cake

But for all you “normal” zucchini loving folks out there, I promise this is one marvelous cake.

  • It does not have the chocolate intensity of some of my other creations, but it is super moist and tender. Again, I took this to a group of my girlfriends to get their opinions. They unanimously praised this chocolate zucchini Bundt cake with chocolate chips. I sent slices home with nearly everyone.
  • Unlike my zucchini bread recipe, the grated zucchini does not need to be squeezed dry. The extra moisture is factored into the baking chemistry.
  • I’d suggest making it in a classic Bundt pan (affiliate link). The chocolate chips tend can stick and so the simpler profile works best.
  • Make sure to prep your pan well with a spray like Baker’s Joy (affiliate link) or grease with butter or shortening and dust with flour.
  • Let it cool on a wire rack for about 15 minutes before attempting to remove it from the pan. Any earlier and it will be too delicate and may break apart as you flip it onto the cooling rack.
  • I usually place the cooling rack, top side down, on top of the cake, then flip both of them over at once.
  • Giving the pan a gentle jiggle back and forth first helps loosen the cake from the pan. Make sure to use hot pads when jiggling and flipping.

  5. Your hubby and my oldest son… It sounds like a great cake and looks very pretty with the pan you used:@)

  6. I’m in that “normal” group of zucchini fans. 😉 This looks delicious and Grumpy would eat this in a heartbeat. He loves chocolate zucchini anything…his only request is he wants white chocolate chips rather than semi-sweet!

  7. My daughter who looks today your blog with me! She said: “I want eat the whole cake, looks so good” 😉

    And sweet desserts with zucchini are seriously one of my favorites – it adds such nice moisture!

  13. Oh, but that pan’s so pretty!!! And the cake looks wonderful. That’s so funny that he spotted the zucchini. Maybe a drizzle of fudgy topping would have him so distracted he wouldn’t notice the flecks of green. Maybe. 🙂

  18. Your mold and your cake are gorgeous, Liz! #pinned

  19. I have to admire your persistence, Liz! I’d call this one a victory since Bill actually ate some of that lovely chocolatey cake.

  20. Next time blindfold him and ask if he could taste the secret ingredient 😀 Isn’t it funny how people are like that? I’d be happy to eat his share of the cake. I love zucchini.

  21. How funny, my hubby gives me a quizzical look whenever I make sweet treats because I always ‘healthify’ them with “normal” ingredients like zucchini 😉 Send his shunned slices my way! oxox

  22. I had just decided to make a chocolate zucchini bundt for our bundt club and then I saw yours on the line up for #SundaySupper. Great minds, LOL. This is truly gorgeous!!

  23. I often get my dad to eat things by baking with them. He won’t touch most fruits, but if I put them in a pie or cake, he’s game. The other day he even ate fresh figs on top of baked oatmeal. I was shocked and pleased he didn’t pick them off.

  24. I can see how it would stick and be a bit annoying BUT I LOVE the shape!! 🙂

    Thanks for sharing, this is a great classic! Have a great Sunday, Liz!

  25. This is the most perfect bundt cake I have ever seen in my life. Wow.

  26. The most beautiful use of zucchini, by far. And I would eat it and not fret about the “green” stuff. But I guarantee you my hubby would say the same as yours.

  27. Lizzy,
    Your cake turned out beautifully. I posted one that was a loaf cake earlier this summer and it turned out being dark chocolate. I bet if you try that one your hubby won’t be able to pick out any of the zucchini.

  28. I so want to try making this cake
    Using zucchini in cakes is not familiar here
    Yours look simply gorgeous !!

  29. Your bundt cake pan is beautiful, this cake is just one more reason I need to get me some zucchini!!

    I love baking with zucchini – it makes my baked goods so moist. I think I’d love this cake.

  31. HI Liz, oh I bet this is delicious and moist. I made a cake like this once and my husband loved it, it’s lentils he won’t get near and a few other things. beautiful shape/mold.

  32. Your swirly cake came out perfectly! I would just eat the cake – I wouldn’t go searching for green bits. Sometimes Bill has too much time on his hands. or his fork. 🙂

  33. Beautiful cake, Liz… I love zucchini cake, both chocolate and non chocolate. I tend to drizzle melted chocolate all over mine, the recipe is on my blog…

  34. baahahahaa Michael would say the same thing! Whenever I try to healthify he always says he likes it but it would be better if –insert thing I changed to healthify that he now wants to revert back to unhealthy version–

  35. I didn’t see any green specks. Tell him to take his glasses off! Looks phenomenal to me, Liz!

  36. Zucchini couldn’t get any tastier! With all that chocolate I wouldn’t notice any green bits, that’s for sure. More cake for you 😉

  37. What a pretty cake, Liz. What a gorgeous cake tin. Now…was there any stress when this had to come out of the cake tin? It’s absolutely perfect. I’m glad Bill enjoyed his unexpected portion of vegetable xx

  38. I love that fancy bundt pan! The cake looks splendid, Liz.

  39. Oh my goodness! I could really go for a huge slice of that cake right now! It looks stunning!

  41. Liz, I’ve been printing out every zucchini based cake recipe this summer and yours is absolutely glorious! Plus, I just received a Nordwic Ware bundt pan in this shape as a gift over the weekend and I can’t wait to use it. I think your recipe should be my pan’s maiden voyage. Maybe instead of using chocolate chips, I’ll grate chocolate so that I don’t have to worry about them sticking. Now I’m all excited! 😉

  42. Liz your Bundt cake is beautiful. I love chocolate and zucchini together. I have a mini bundt cake pan that I should break out of the drawer some time. Great recipe!
