I’m totally new to the world of zucchini in baked goods. I can do carrot cake because the carrots are hidden, but I was nervous about this one. But it worked out! It was awesome and I can’t wait to try other zucchini recipes. Especially those with chocolate. ;)

Zucchini and veggies just aren’t my thing. If you follow me on Instagram, you know that I bought a cucumber, thinking it was a zucchini. What can I say? They’re both long and green. Thank goodness Mr. Texanerin questioned my cucumber intentions! Or else there would’ve been cucumber cake. Yuck. Actually, I dislike zucchini too so maybe it doesn’t really matter. And by the way, you can not taste the zucchini in this zucchini cake. You can believe me when I say I would not eat this if you could.

So that’s what the cake looks like without the ganache. A bit boring, yes? And weird. The second cake I made came out looking normal. Without all those little holes. I had to make the cake twice. The first time I used a 6 cup bundt pan (it halves wonderfully!), thinking it wouldn’t work out. But then it did. And since I can’t just guess the baking times, I had to bake it a second time using a normal 12 cup bundt pan.

So much better, isn’t it?! And oh oh oh! This ganache… it’s not really ganache. Ganache = chocolate + cream. This is cocoa powder, honey, coconut oil, and Greek yogurt. Yeah! :D It sets like normal ganache, but you should keep it in the fridge because of the yogurt. And it honestly tastes just like real ganache.

100% Whole Grain Chocolate Zucchini Cake with Greek Yogurt Honey Chocolate Ganache
  • Prep Time:
  • Cook Time:
  • Ready in:
  • Yield: 12-14 pieces

Ingredients

    Zucchini cake:

  • ¾ cup (177ml) olive oil or canola oil
  • 1 cup (320 grams) honey
  • 2 teaspoons vanilla extract
  • 2 large eggs
  • ¾ cup (177ml) Greek yogurt
  • 290 grams whole wheat flour (this was about 2 cups or 2¼ cups)
  • 1¼ teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 90 grams Dutch-process cocoa powder (about ¾ cup cocoa)
  • 3 cups (for me, this was 340 grams) grated, peeled zucchini1
  • 1 cup (180 grams) semi-sweet chocolate chips
  • Ganache:

  • 80 grams (¼ cup) honey
  • 50 grams (3½ tablespoons) coconut oil
  • ½ teaspoon vanilla
  • ¼ cup (30 grams) Dutch-process cocoa powder
  • 2-4 tablespoons Greek yogurt

Directions

  1. Grease a 12 cup bundt pan or 6 cup if you want to make half. Preheat your oven to 350°F / 176°C. For the cake, combine the honey, oil, and vanilla in a large bowl. At first it'll be difficult to get the honey incorporated, but it'll work. Stir in the eggs and then the Greek yogurt. Set this bowl aside.
  2. In another large bowl, combine all the dry ingredients. Sift the cocoa powder into the bowl if it's lumpy, or just use a fork to get rid of the lumps. Add the wet mix to the dry mix and stir, just until combined. Fold in the zucchini and the chocolate chips.
  3. Bake the full recipe for 40 minutes, or if using half, bake for 30 minutes. When you insert a toothpick in the middle, the toothpick will not come out dry, or even with crumbs, but it'll come out covered in sticky batter. If you insert it, and it's just normal batter, it's not ready. Sticky batter is what we're looking for! It'll continue to cook once it's out of the oven.
  4. Let cool in the pan for 10 minutes and then flip out onto a wire rack to cool. Cool completely before putting on the ganache. If using the following ganache recipe, store cake covered in the fridge. Otherwise, room temperature is fine.
  5. For the ganache: Over low heat, melt the honey and coconut oil and in a medium saucepan or pot. When melted, add the vanilla and then the cocoa powder. Stir until thoroughly combined. It might look weird, like it isn't combining. The first time I made it, I used too much coconut oil and poured some out and everything was fine. The recipe reflects how I made it the second time with less coconut oil, and had no problem with excess oil.
  6. Place in the fridge for 5 minutes. Take out and add a tablespoon of Greek yogurt at a time, stirring after every one. For me, just under three tablespoons was enough. It should be pourable at this point. Not too hot and not too cold. Pour over the cake and store any leftovers in the fridge.

Notes

  1. The first time, I grated the zucchini. The second time, I put it through the food processor using the super finer grater. But it really came out more like puree. With the puree, I used 1.5 cups because that's what 340 grams came out to. I think I actually preferred it with the grated zucchini. The texture just seemed better and the little pieces disappeared anyway, so you can still trick people. :)

      Definitely! A few commenters have made them as muffins but I’m not sure how long they baked them. My guess is 12-18 minutes.

      I haven’t tried it but I think it would. If you had a choice, I’d probably freeze the cake unfrosted and add the frosting after baking.

      If you try it, I hope your girls will enjoy them (and happy birthday to them! :)) Someone else in the comments made these as cupcakes and said they came out well but they didn’t say how long they baked them. I’m just going to guess here, but I’d say 12-17 minutes. It’s just a guess, though! I’d keep a close eye on them and then when they no longer look wet on the top, test them with a toothpick. It’ll probably still be wet inside and need another 2-3 minutes. Let me know how they come out if you try them! :)

    I make this cake into breakfast muffins using a large muffin pan. I have to say this cake is fantastic!! I do use vanilla yogurt, as the taste of the plain is just to strong for me. I drizzle the ganache on top and watch as these are wolfed down. The best part is when I tell people they have zucchini in them. I have been called a liar more than once lol..thanks for this recipe, I will be making more treats from your site.

    i just made this and the center never set. it’s still raw. i put it back in for 15 minutes and still way too gooey. The only thing i can think is that i didn’t really drain the zuchinni first but it didn’t say to anywhere in the directions. is that the problem?

      January 25, 2014 @ 10:15 pm

      Oh no. Sorry it didn’t come out! I hope it eventually set. I’ve made this cake a few times and never drained the zucchini. The only thing I can think of is that you finely grated your zucchini and were therefore able to pack in a lot? There’s a note about that at the bottom of the recipe. If that’s not the case, I have no idea what could have caused the problem. Sorry again!

    My 15 yr old daughter made this cake for her Dad’s Birthday yesterday…it turned out really good. We left out the yogurt as she has a dairy allergy…it was still super moist. We put a simple orange glaze on top instead of the ganache…just wasn’t sure how to substitute the yogurt in the ganache. Everyone loved it.

      That’s not awful at all, Denise! I don’t have that info but Caloriecount has a nice recipe analyzer you could try using. :) This recipe is healthier than a normal cake but still not diabetes friendly so I’m guessing it’d need a lot of tweaking. Good luck! I hope you all enjoy it. :)

    I just made this for my daughter's 1st birthday and it was a huge hit! Great recipe, and we're going to pretend it's healthy enough for breakfast :) Next time I will make it as a bundt or cupcake, though. I tried to be clever and bake it in a cute shape for her birthday, but had to cook it longer because the center remained gooey and so the edges were a little over baked. This is definitely a cake that does best with no center to worry about. Even over baked it's fantastic, though!

    Love it. Absolutely LOVE it. This cake looks so yummy, I'm drooling all over my brain here. And for the record, I think the "naked" cake looks unbelievably good, not weird at all. It lets you see the texture of the cake, which does look like it's very dense and "wet".

    My kinda cake. I will definitely have to try it (with a few little tweaks, of course…)

    Oh, and I can't believe you showed us the holes. I couldn't help but start laughing. That IS a lesson indeed! And a very valuable one at that!

    Barbara – Thank you! Ganache pouring has always been a challenge for me. This time I was just lucky. And I only use natural light. I've tried making a light box and making DIY Ego lights and neither one worked for me. Let me know if you do get some kind of lighting setup. I'd love to know how it works! We're both in the same boat when it comes to light pretty soon. It gets dark up there early and over here, it's just constantly gray. We've seriously gone weeks before without any sun. Just grayness. Whenever I wake up and it's actually sunny, I have to run to the kitchen and bake, bake, bake.

    Lauren – The ganache is amazing! You have to try it. I couldn't believe that it actually tastes like ganache and not some healthified watery bittery… something. :)

    Spencer – I bet you would! But you really can't taste the zucchini. I was sure you kill any veggie taste. Can't have that around here. :)

    Natasha – Haha. Well I'm happy I called it the right thing. I had it typed up as milk _____________ for the last week. I just went with jug. Thanks for playing along with my silly ideas. :D

    Shelly – I promise you can't taste it! It tastes the same as if using canola oil. When you taste the batter, you can taste it, but once baked, that yucky taste goes away. :) And yeah, having you at the tea party would've been fun! We only had Maker's Mark, though. No tea.

    Miryam – You should post your version! I'd love to try it. And this was my first time baking with zucchini! Definitely won't be the last. I hope you like the apricot muffins. :)
