Hang onto your seats, chocolate lovers. Are you ready for a supremely delicious cake recipe? Because have we got one for you! This chocolate zucchini cake is rich, chocolaty, and irresistibly good. Even if you don’t eat gluten free or dairy free (which we don’t), it’s an inventive way to eat real, whole foods in dessert form! This cake has gone on to be a family favorite in our household. The zucchini makes it ultra moist, and it’s gooey and just sweet enough. It’s truly a stunner! Here’s how to make it.

Ingredients in chocolate zucchini cake

Alex and I don’t subscribe to a specific diet, but we love the creativity making whole food recipes for people with different food philosophies. Often we create gluten free and vegan desserts for everyone to enjoy, like our fan favorite chocolate peanut butter bliss bites. That’s exactly the philosophy behind this gluten free dairy free cake!

Here are the ingredients you’ll need for this chocolate zucchini cake. You’ll notice they’re all good for you whole foods: so you can feel good about serving it to your family!

  • Almond butter This adds fat and texture, instead of butter! For nut allergies, use sunflower butter.
  • Zucchini Shredded zucchini brings moisture and a fluffy texture!
  • Maple syrup
  • Cocoa powder
  • Egg For vegan, use a flax egg
  • Vanilla extract
  • Baking soda
  • Dark chocolate chips If you eat dairy free, use dairy-free chocolate chips
  • Instant coffee powder (optional)

How to serve chocolate zucchini cake

From the first bite, this chocolate zucchini cake was a favorite in our house! It’s surprising how the texture of all the ingredients comes together into something cake-like, even though there’s no flour present.

This cake would be perfect for a summer cookout, since it would satisfy almost every diet in the crowd! Usually we eat it plain, but here are some ways to step it up! Serve it with:

Variations: make it vegan!

Want to make this chocolate zucchini cake vegan? It’s already dairy free, but it’s got 1 egg. How to make it vegan? Use a flax egg! A flax egg is simply ground flax seed and water, which combine into a binder that’s often used in vegan baked goods. It works well here as a binder for this cake, especially since it’s a sheet cake. Head to How to Make a Flax Egg.

Description

This chocolate zucchini cake recipe comes out so rich and chocolaty! It’s a family favorite that happens to be dairy free and gluten free to boot.


Ingredients

Scale
  • 1 cup creamy unsweetened almond butter (or sunflower butter)
  • ⅓ cup pure maple syrup
  • ¼ cup cocoa powder
  • ¼ teaspoon kosher salt
  • 1 teaspoon instant coffee powder (optional)*
  • 1 large egg (or flax egg for vegan)
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon baking soda
  • 1 ½ cups shredded zucchini (about 2 small)
  • 1 cup dark chocolate chips, dairy-free as desired
  • Coconut oil, for the pan

Instructions

  1. Preheat the oven to 350F. Grease an 8- or 9-inch square pan with coconut oil. If you want to remove the cake from the pan in one piece, line it with unbleached parchment paper as well.
  2. In a large bowl, stir together the almond butter, maple syrup, cocoa powder, salt, coffee powder, egg, vanilla, and baking soda until fully combined and a sticky dough forms.
  3. Stir in the zucchini and chocolate chips.
  4. Pour into the prepared pan and bake until just set and a toothpick inserted in the center comes out clean or with dry crumbs. Do not overbake. A 9-inch pan will take about 30 minutes; an 8-inch will take about 35 minutes. Remove from the oven and allow to cool before serving. Stores covered at room temperature for 1 day or refrigerated up to 4 days.

Notes

*Instant coffee powder enhances the chocolate flavor in baked goods. It is completely optional though. There are coffee alternatives, such as Pero, which is a chicory and barley-based product with no caffeine. Pero is not gluten free or grain free, due to the barley. Do not use coffee grounds in place of instant coffee powder. Reprinted with permission from Kitchen Matters by Pamela Salzman

    I made it tonight for a dinner party and they said it was really good and moist, . Super easy to make. I served it with fresh raspberries that I just picked from our garden and vanilla ice cream

    I used unsweetened almond butter and HU Chocolate.

  2. Denise F says:

    Just made this cake and it was AMAZING. Better than any other chocolate cake I have made, and I have made a lot. You CANNOT taste the almond butter, syrup or Zucchini. It tastes like a delicious flourless chocolate cake. I used Ghirardelli 60% cocoa chips and 100% Ghirardelli cocoa powder and it was amazing. This will go in my recipe book for years of use.






  3. Angela says:

    Ummmm, did I miss something?
    It never solidified. It was just gobbly gook- this was after cooking it for a hour to see if it would harden. What makes the structure of the cake stick together? There is no flour, etc to adhere to the ingredients. Was there a missing ingredient on that recipe? I ended up tossing it (I hardly ever do that, but it was inedible)

    1. Sonja Overhiser says:

      We’re so sorry to hear this! This is a recipe shared from another author’s cookbook, so we can’t full speak to her recipe. We made it successfully and it was delicious! It is a flourless chocolate cake so it does not have flour. You included the egg, correct? Did you use a 9 x 9 or 8 x 8 pan? Did you leave out any of the ingredients, like the chocolate chips, or did you follow it exactly? Let us know!
