Jump to Recipe Print Recipe

It's the first Monday of the New Year and I don't know about you, but I can only think about chocolate. There is no reason not to enjoy a slice of cake, or two in January! So, get your baking ingredients back out because it's time to whip up the best vegan gluten free chocolate cake recipe you will ever have!

What you’ll get with this recipe:

full shot of chocolate cake with espresso buttercream on parchment paper.
  • Moist, soft chocolate sponge
  • Espresso buttercream that you'd never tell is vegan
  • Espresso buttercream piled as high as your heart desires
  • Perfect cake for any occasion (or any day of the week)
  • Rich and decadent

Ingredients For Vegan Gluten Free Chocolate Cake

  • Cassava flour
  • Cocoa powder, sifted!!
  • Granulated sugar, cane sugar or coconut sugar work best!
  • Olive Oil
  • Apple Cider Vinegar
  • Brewed coffee
  • Vanilla, baking soda, salt, and water
  • Powdered sugar
  • Vegan butter
  • Espresso powder

The Instagram post for this recipe was sponsored by Edward and Sons Trading Co., however, this blog post is not sponsored and I just wanted to share this awesome recipe with my non Instagram blog followers! 

2 slices of olive oil chocolate cake on pink plates with forks and a small jar of cocoa powder.

The icing on the cake, yes the literal icing on the cake, is topped with Edward and Sons Confetti Sprinkelz! To achieve a soft, moist crumb, I also used their Cassava Flour. Cassava flour has a very subtle flavor and the texture is incredibly perfect, you'd never know it was gluten free.

How To Make Vegan Gluten Free Chocolate Cake

You will find full instructions and measurements in the recipe card at the bottom of the post. This is a summary of the process.

  • Sift together cassava flour and cocoa powder, and then add sugar, baking soda and salt.
  • Marry your olive and apple cider vinegar and let it sit for just a minute.
  • Add olive oil and vinegar mixture, vanilla, cold coffee, and cold water to your dry ingredients.
  • Add cake batter into a 9x13-inch pan (greased and lined with parchment paper)
  • Bake at 350F for 30-35 minutes. Allow cake to cool for a few minutes before transferring to a wire rack to cool completely.
  • Make vegan buttercream, by beating butter until light and fluffy.
  • Add softened powdered sugar, cocoa powder, and espresso powder.
  • Frost cooled cake and top with sprinkelz.

RECIPE TIPS

Cassava flour. I have had luck using regular all purpose flour in place of cassava flour, but still think cassava will give you the best, most satisfyig texture. I don't recommend trying this chocolate cake recipe with any single type of gluten free flour such as almond or coconut flour.

Instant espresso powder. You only need a little in this recipe to make the buttercream really stand out and add a great depth of flavor. You can also use instant coffee!

Vegan butter. Miyokos Vegan Butter or Earth Balance Buttery Sticks work best here! Be sure to cream the butter until there are no clumps and it become slight and fluffy. Vegan buttercream will always be softer than a traditional buttercream frosting since it's oil based. So, if you wish to pipe your buttercream, pop it in the fridge for 5-10 minutes to slightly firm up leaving it soft, yet pipe-able.

Cake to cupcakes. You can definitely make this gluten free chocolate cake into cupcakes! Just adjust your baking time as needed and grease and line your muffin tins. Be sure to read how to make pipe-able vegan buttercream right above!

Make Ahead, Storing, and Freezing Tips

You can make the chocolate cake sponge ahead of time and wrap the cooled cake in plastic wrap 24 hours in advance.

Keep it stored in an airtight container or on a cake stand at room temperature for 2-3 days. Or you can keep it in the fridge in an airtight container for up to 5 days. It is also freezer friendly for up to a month if you want to freeze it.

    LOVED this recipe! I came home from college for the weekend to celebrate my birthday and my Mom and I decided to try this one out. We are SO glad we did! This easy-to-make, delicious cake had the perfect mix of chocolate and coffee flavor and put the cherry on top of a sweet birthday weekend. 🙂
