Gluten Free Chocolate Zucchini Cake

Gluten Free Chocolate Zucchini Cake

One of the best things about summer — to me — is that I can grab tons of fresh zucchini at farmer’s markets for recipes like this gluten free chocolate zucchini cake! I’ll look for any excuse to hide, er, I mean to use, fresh veggies and fruits in my baking, and this “hidden treasure” recipe for gluten free Chocolate Zucchini Cake is one of our favorites!

While you might not think that zucchini and chocolate could marry so well, just wait until you taste this amazing gluten free chocolate zucchini cake!

Besides being delectably moist and delicious, this chocolate cake contains health benefits you can’t taste — talk about having your cake and eating it too!

The glaze on top is a delicious alternative to traditional frosting, but is totally optional. At times, I’ve shaved some dark chocolate on top (also optional) for decoration, and on other occasions, I’ve baked this yummy cake as a sheet pan and used cookie cutters to cut out shapes.

Use cookie cutters to cut fun shapes out of cake and serve with fruit for bite-sized cake fun!


The recipe is so versatile, I’m sure you’ll come up with even more ways of using it or feeling smug about sneaking veggies into your family without their ever suspecting it.

I mean, do you see any zucchini in this luscious cake?

My kids (and my parents) sure haven’t. Or that it hasn’t stopped them if they have!

This light, subtly sweet cake is sure to be a hit for you this summer and fall. In fact, when I first made this cake years ago (many years ago), my young son and his friend spied the green ingredient before I could secret it away. They were good sports — or maybe they just really love chocolate — and surprisingly wanted to try the cake anyway.

In the words of my son’s playdate pointing to this cake, “I don’t know if there’s gluten in that or not, but that chocolate cake is GOOD!” And here I was worried about the zucchini!!

For other gluten free chocolate zucchini combos, try my gluten free Coffee Chocolate Zucchini Bread or my gluten free Zucchini Brownies! Or even my gluten free chocolate zucchini donuts! I think you’ll agree it’s truly a great combination.

Note: although this recipe was originally published in my cookbook, Free for All Cooking, since then I’ve experimented more with Coconut Palm Sugar – a low glycemic, granulated, raw and nutrient rich alternative to processed sugar. I’m happy to report that this recipe worked beautifully using coconut palm sugar, so consider that an option if you’re looking to feel even better about eating chocolate cake!

Gluten Free Chocolate Zucchini Cake – no glaze required!


And while I give you and easy and delicious glaze recipe, there’s no need to glaze this yummy cake. A light dusting — or dotting, as it were — of confectioner’s sugar is just as yummy!

Especially if you’re not serving this cake right away, I’d recommend not glazing it. Just serve it au natural. It’s so light and tasty on its own. But you be the judge. Maybe try a piece both ways and decide for yourself!

So hit your local farm stand or even the grocery store and start shredding!

You’ll wind up with 2 1/2 cups of zucchini, which should look like this (it’s approximately 1 1/2 average sized zucchini)

No need to drain it for this recipe, just shred and add. Couldn’t be easier!

Enjoy sneaking greens into your chocolate cake. I hope you feel as smug about it as I do!

As if we needed another reason to love zucchini, this gluten free Chocolate Zucchini Cake makes zucchini impossible to resist!



  • 2 1/2 cups (337 grams) gfJules™ Gluten Free All Purpose Flour
  • 1/2 cup (54 grams) unsweetened cocoa powder (natural, not Dutch processed)
  • 3 teaspoons (9 grams) baking powder
  • 1 1/2 teaspoons (8 grams) baking soda
  • 1/2 teaspoon (3 grams) salt
  • 2 teaspoons (4 grams) ground cinnamon (optional)
  • 3/4 cup (6 ounces) butter or vegan alternative Earth Balance® Buttery Sticks
  • 1 2/3 cups granulated cane sugar OR coconut palm sugar
  • 3 eggs (or egg subs of choice – see Free for All Cooking or my article*
  • 2 teaspoons pure vanilla extract
  • 2 tablespoons agave nectar, honey OR raw coconut nectar
  • 1 tablespoon orange juice or apple cider or other juice of choice
  • 2 1/2 cups coarsely shredded zucchini (approx. 1 1/2 ave. zucchini, not drained unless particularly wet)
  • 1/2 cup milk or non-dairy milk

Glaze (optional):

  • 1 cup powdered sugar
  • 1 1/2 tablespoons milk or non-dairy milk
  • 1/2 teaspoon pure vanilla extract
  • shaved milk chocolate or dark chocolate or chocolate chips (optional)


Preheat the oven to 350° F.

Prepare a 10-inch tube or bundt pan by lightly oiling and dusting with gfJules™ Flour. Or, prepare a 9 x 13 baking pan the same way, and bake as a sheet pan.

Wash and grate zucchini with skins on. If you have extra grated zucchini, measure it and bag it, then refrigerate or freeze for your next yummy zucchini recipe!

Whisk together gfJules Flour, cocoa, baking powder, baking soda, salt and cinnamon; set aside.

Using an electric mixer (preferred), cream butter/Buttery Sticks and sugar until smooth and light, at least 3-4 minutes. Add eggs or substitute to the butter and sugar mixture one at a time, beating well after each addition. Stir in vanilla, agave/coconut nectar, juice and finally, zucchini.

Add the mixed dry ingredients and the milk alternately into the zucchini mixture until fully incorporated.

Pour into prepared pan and bake in the preheated oven for about 50 minutes (test at 45 minutes) or until a skewer or cake tester inserted into center comes out clean. Cool in pan for 15 minutes; gently turn out onto a wire rack to cool thoroughly.

Sprinkle confectioner's sugar over the cake to serve, or to make glaze, whisk together all the ingredients until smooth. Drizzle glaze over cake only after it has fully cooled.


*For egg-free/vegan, reader Joanne S. used 3 TBS flaxseed meal mixed with 6 TBS hot water (steeped for 10 minutes) and 1 recipe Ener-G egg Replacer.

I hope you love this recipe as much as we do!

Pin it for when those chocolate cravings hit!

  1. This was the best gluten free cake I have made in years, moist, chocolate and wonderful! Non gluten free people loved it also! Used a combination of rice milk and whipping cream for my milk ingredient, will make it again but not too soon, I have no stopping power when it comes to this cake!

    Keep them coming Jules!

  2. This cake is absolutely amazing!!! I’ve been GF for about 12 years and this is by far the best cake recipe ever:). Moist, full of flavor, Delicious!!! Well done!!

    • Oh Sharon, that is the best news! I’m so glad you loved it!!! May all your baking be so happy from here on out!

  3. This Chocolate Zucchini Cake is amazing! It’s very moist and has just the right amount of chocolate flavor. I used Monk fruit instead of sugar and it worked just fine. Thanks for a great recipe!!

    • So happy to know this gluten free Chocolate Zucchini Cake recipe worked well with the Monk Fruit in place of sugar! Thanks so much for letting me know, Sheryl! Happy baking!

  4. I made this cake last night. It was very good. My Mother who will not put anything gluten free in her mouth, ate some and liked it. I did add a little more milk to the mixture as I got a little heavy handed with the zucchini. Didn’t have any chocolate chips, but had some salted caramel chips. Sprinkled this on the cake, really set it off. Served with a glass of coconut milk, YUM!!

    • You gotta love with the gluten lovers among us endorse a gluten free recipe! Congrats on your success with this gluten free Chocolate Zucchini Cake, Linda!!!

  5. Not sure what went wrong. Very dry and crumbling. Thank goodness I didn’t tip it upside down like I normally would. Im spooning it out and putting ice cream on top.
    Please reply.

    • Hi Caron, first off, I’m so glad to hear that you’re making the best of it! That’s the true baking spirit I love to see!
      Can you tell me whether you used my gfJules Gluten Free Flour? Any other substitutions for ingredients? What was the batter like before baking?

  6. Made this for the first time for my husband’s birthday. Couldn’t have been happier with the results! Instead of the expected sawdust and crumbling that comes with gf baking, we had a moist and rich chocolate cake. I would omit the cinnamon next time. Not necessary to us. I definitely recommend adding the powdered sugar or the glaze. The chocolate is strong and you need a little sweet to cut it. Will definitely make this again!

    • Hi Susan, thank you so much for coming back to report on your cake made with this recipe. I hope your hubby had a very happy birthday (we know it was tasty!).
