BEST Vegan Gluten Free Chocolate Cake Recipe

You’ll love this super easy vegan gluten free chocolate cake!

If you’ve been looking for the best gluten free vegan chocolate cake recipe around, then look no further. You have ARRIVED.

You are just going to love this gluten free chocolate cake for a few reasons. The taste is just perfect: super rich, decadent, chocolatey, and sweet. And the texture is soft, moist, and tender. Paired with this easy vegan chocolate frosting, it’s a dream in a bite.

Then we have the best part about this easy gluten free vegan cake recipe: it’s made with just oat flour as the main flour (no other flours!), is naturally oil free (just applesauce and vegan buttermilk!), and is entirely nut free, eggless, and dairy free.

Not to mention, this chocolate cake recipe is the definition of easy. You simply mix everything together in a bowl and bake! It couldn’t be simpler!

Ingredients:

As I mentioned above, you’ll only need a few simple ingredients for this easy gluten free chocolate cake recipe. This chocolate cake recipe is entirely oil free, eggless, and dairy free, so the ingredients are all plant based and vegan as well.

For this cake, you’ll need:

  • Oat flour: The gluten free flour that we’re using for this vegan glutenfree chocolate cake is actually just oat flour! You can use store bought oat flour, such as by Arrowhead Mills or Bob’s Red Mill, or make your own, like I did. I recommend using One Degree Organics for a great texture in the cake. I don’t recommend using a gluten free flour blend here, however. If you’d like a gluten free vegan chocolate cake using a gluten free flour blend, you can try my original classic vegan chocolate cake. This cake was specifically designed for oat flour!
  • Cocoa powder: you can also use cacao powder if you really want to. However, the acidity in natural cocoa powder will help this cake rise more. So keep that in mind!
  • Coconut sugar: using coconut sugar will keep this gluten free chocolate cake entirely refined sugar free. However, you can also use maple sugar, a keto-friendly sugar, or even regular granulated sugar.
  • Arrowroot starch: this is interchangeable with cornstarch.
  • Applesauce: I used unsweetened applesauce here, which acts as the egg replacement from regular chocolate cake recipes.
  • Dairy free milk: this will be mixed with a touch of apple cider vinegar to make a vegan buttermilk! You can use oat milk, cashew milk, soy milk, or whichever dairy free milk is your favorite. 
  • Leavening agents: just your baking soda and baking powder- pretty standard baking ingredients here! 🙂

Never made a vegan cake with oat flour before?

Not to worry- if you’ve never made a cake with oat flour before, then you’re in for a treat. When combined with arrowroot starch or cornstarch, the texture is sublime. Soft, tender, and perfectly fluffy. It is a bit more delicate than regular flour. However, it makes for a great substitute for anyone who’s gluten free and doesn’t want to use gluten free 1:1 baking flour.

If you’ve tried my vegan gluten free vanilla cake that uses oat flour, then you’re going to really just fall in love with this chocolate version. 

How to make an eggless chocolate cake:

You might be wondering how the heck we’re going to achieve a vegan gluten free chocolate cake without any eggs. After all, in traditional baking, eggs give a cake recipe its lift and rise, along with stabilizing the cake. 

However, you can still achieve a well risen, structured vegan cake without eggs. Our vegan egg replacement for this vegan gluten free chocolate cake is using applesauce.

Here, we’ll go over a brief overview of the steps, along with providing visuals for a better understanding of the recipe. 

To make this easy chocolate cake recipe, here’s what you’ll need to do:

  1. Whisk together the dry ingredients.

  3. In a separate bowl, mix together the coconut sugar, applesauce, and dairy free milk.
  4. You can just use a whisk again!

  5. Then, add the dry to the wet

  8. You can use 6″ cake pans or 8″ cake pans.

The Vegan Chocolate Buttercream Frosting

For the frosting of this gluten free chocolate cake, we’re using my all time favorite, vegan chocolate buttercream frosting. This recipe can be made either with coconut sugar or with powdered sugar, and it’s so freaking easy.

The biggest tip for the frosting is ensuring that your vegan butter is about 65-68F. This will ensure that the vegan butter isn’t too soft that it won’t become creamy and fluffy when mixed.

This frosting is ultra lush, rich, decadent, and smooth, all while being naturally dairy free. For vegan butter brands, I recommend Miyoko’s vegan butter or Flora Plant Butter- this will give you the closest taste to true chocolate buttercream, and it’s a great sub if you’re new to vegan baking!

Can this cake recipe be used as a smash cake?

Since babies shouldn’t have cocoa powder until at least 24 months old, this gluten free vegan chocolate cake shouldn’t be used as a smash cake for a first birthday. However, we do have a smash cake-friendly vanilla oat flour cake recipe on the blog, that would work perfectly! You can swap out a few of the ingredients as needed, depending on what your baby prefers (and what’s recommended by your pediatrician).

Can I use another flour for this gluten free vegan cake recipe?

This gluten free vegan chocolate cake recipe is actually specifically designed for using oat flour cake. This is because I’ve seen tons of amazing vegan chocolate cake recipes on the web that use almond flour or coconut flour, but I wanted to contribute something different!

So unfortunately, if you can’t use oat flour, then I recommend a different chocolate cake recipe (or maybe trying my vegan chocolate cake recipe with gluten free 1:1 baking flour! That’s been approved!).

Recipe Tips & Tricks

The applesauce: I recommend sticking with applesauce for this vegan chocolate cake recipe. You can use mashed banana, but there will be a bit of a banana flavor to the cake. If that doesn’t bother you, then go for it! I do not, however, recommend swapping in a flaxseed “egg” here. Great for other recipes, but not for this one!

Use room temperature ingredients: this is super important, whether you’re making a regular cake or a gluten free vegan cake. Not using room temperature ingredients will yield a super gummy texture, rather than moist and soft.

Vegan buttermilk: this is the best trick for getting a fluffy and soft gluten free vegan cake! I used oat milk here, but you can use any dairy free milk that you’d like.

Allow the cakes to fully cool before frosting: if you don’t want your cakes to fall on the floor as you frost, then allow the to fully cool before even making the buttercream! I usually give the cakes about 45 minutes to rest after baking. Then you can make the frosting!

How to decorate a layer cake:

This is the really fun part! Once you’ve fully frosted your cakes, you can make any design you’d like. I love to top my gluten free vegan cakes with fresh fruit and flowers.

You can also pipe regular vegan buttercream colored with vegan food coloring for fun floral buttercream decorations.

Some other topping ideas include:

  • Vegan chocolate chips
  • Crushed nuts (if not nut free) or chia seed
  • Edible flowers
  • Vegan candy
  • Vegan fondant decorations

Description

This easy  vegan gluten free chocolate cake is the ultimate chocolate cake recipe! Super moist, decadent and rich, you won’t believe that this healthier chocolate cake is made from just oat flour, is completely oil free, and naturally eggless, dairy free, and refined sugar free! This chocolate cake recipe is stress-free, minimal ingredients, and downright DELICIOUS!


Ingredients

Units Scale
  • 1 1/2 cups (350 g) unsweetened dairy free milk + 1 tsp acv, room temperature, mixed before the batter
  • 3 cups (360 g) oat flour, sifted
  • 2/3 cup (65 g) cocoa powder
  • 2 tbsp arrowroot powder
  • 1 1/2 tsp baking powder
  • 1 tsp baking soda
  • 1 1/2 cups (375 g) unsweetened applesauce or dairy free yogurt, room temperature
  • 1 1/4 cups (250 g) coconut sugar or organic granulated sugar
  • 1 batch vegan chocolate buttercream

Instructions

  1. Please read through all instructions before beginning.
  2. Prep: preheat the oven to 350F. Grease and line three 6″ cake pans with cooking oil and parchment paper, and set aside. Measure out all ingredients. Mix together the dairy free milk and apple cider vinegar in a small bowl, and set aside to rest for 5 minutes. This will be called the vegan buttermilk going forward.
  3. Whisk together the dry ingredients: in a medium bowl, whisk together the oat flour, cocoa powder, arrowroot powder, baking powder, and baking soda. Set aside
  4. Make the batter: in a large bowl, whisk together the vegan buttermilk, applesauce, and coconut sugar. Add in the dry ingredients, and whisk gently to combine the dry ingredients into the wet. Mix until just combined.
  5. Bake: pour the batter into the three prepared pans evenly, and place into the oven to bake for 37-40 minutes, or until a toothpick comes out clean. Remove the cakes from the oven and allow the cakes to cool in their pans for 10 minutes. Then carefully transfer them to a cooling rack to fully cool before frosting. There should be no heat within the cakes at all prior to making the vegan buttercream.
  6. Make the frosting: once the cakes are cooled, you can make the vegan chocolate buttercream frosting according to the directions. 
  7. Frost the cake: apply about 1/3 cup of chocolate frosting between each layer, and frost the remainder of the cake. Decorate as you’d like (fresh fruit is my favorite!), and slice and serve!
  8. Storage: store any leftover slices in the fridge in an airtight container for up to 5 days. Alternatively, you can freeze this cake in an airtight container for up to 2 months.

Notes

Oat flour: you can use store bought oat flour or homemade oat flour. Homemade will give you a more rustic look, like the photos. 

Arrowroot powder: arrowroot is found as either arrowroot starch or arrowroot powder, depending on the brand. You can also use cornstarch at a 1:1 ratio. 

Refined sugar free: to keep this gluten free vegan chocolate cake entirely refined sugar free, using coconut sugar for both the cake and the frosting.
