Vegan Chocolate Peppermint Cake Ingredients

You’re going to love how simple these ingredients are. Here’s what you need to make this amazing Christmas cake:

  • Oat flour: I recommend using store bought oat flour if you want a vegan gluten free cake that truly doesn’t taste vegan nor gluten free. If you use homemade oat flour, the cake will have a bit more of a rustic feel to it and taste a bit oat-ier. Still a wonderful flavor, but it depends on what you’re going for.
  • Cocoa powder: I recommend using Valhrona cocoa powder- it’s truly amazing! Please try not to use cacao powder though, as cocoa powder has more acidity and will help your cakes to rise better. Since this is a vegan chocolate peppermint cake, we need all of the rise we can get, as there are no eggs in it. Using cacao powder might hinder your cakes from rising properly.
  • Unsweetened applesauce: This acts as the “egg” and adds a bit of natural sweetness, helping reduce the sugar.
  • Organic sugar: I recommend using organic granulated sugar, such as Wholesome Sweets or Florida Crystals, as these two brands are vegan. Not all sugar is vegan unfortunately, but buying organic means they’ll use beet powder to whiten the sugar. You can also use coconut sugar, which would then make this cake refined sugar free as well!
  • Peppermint extract: Make sure you’re using a food grade peppermint extract, and not peppermint oil.
  • Vanilla extract
  • Dairy free milk: You can use soy milk (I love Forager Project’s new soy milk!), oat milk, cashew milk, almond, or coconut milk! We’ll mix this with a touch of apple cider vinegar to create a vegan buttermilk. You can also skip this entirely and just use Forager Project’s drinkable unsweetened cashewmilk yogurt. It acts just like buttermilk!

Not outlandish ingredients, right? The only note I want to make is that if you’re nut free, definitely go with coconut or oat milk, or even soy milk.

For the full written instructions and ingredient measurements, see the bottom of this post in the recipe card. You can also hit the “jump to recipe” button at the top of this post! Here, we’ll go over a brief overview of the steps, along with providing visuals for a better understanding of the recipe.

The best part about this vegan and gluten free cake recipe is that it is just so easy. You just need one main mixing bowl, and not even a hand mixer to do the work!

Here’s how to make this amazing vegan chocolate peppermint cake:

  1. Whisk together the dry ingredients.

    This is the oat flour, arrowroot starch, cocoa powder, and leavening agents. You’ll set this aside once mixed.

  2. Then combine the wet ingredients.

    In a large bowl, use a whisk to mix together the applesauce, sugar, vegan buttermilk, peppermint extract, and vanilla extract.

  3. Fold in the dry ingredients.

    Use a whisk or a rubber spatula to fold in the dry ingredients to the wet.

  4. Bake the cakes!

    Divide the cake batter into three 6″ cake pans (or 8″ cake pans! If you’re using 8″ or 9″ cake pans, you can double the recipe to get the even, thick layers), and bake! You’ll know the cakes are finished once a toothpick comes out clean.

How to Make Vegan Vanilla Peppermint Buttercream

Making a vegan vanilla frosting has become my go-to for all of my cake recipes ever since my vegan vanilla cake. It quite literally is the best vanilla cake ever, and the frosting is a huge part of that!

If you want to make your vegan chocolate peppermint cake with chocolate frosting, you absolutely can! My recipe for an easy vegan chocolate buttercream is one of my favorites as well. You can add in a teaspoon of peppermint extract to the frosting too. Sprinkle with crushed candy canes and you’re good to go!

Personally, I felt that the chocolate on chocolate might be overwhelming because this cake is sooooo fudgy and rich. But my fiancé, Jared, loves anything chocolate, and he prefers the double chocolate that way!

So back to the vegan vanilla frosting. You’ll need:

  • Vegan Butter
  • Powdered Sugar
  • Vanilla Extract
  • Peppermint extract

Super simple, and you basically make it like any other buttercream frosting!

  1. First begin creaming the softened vegan butter in a large bowl with a hand mixer or stand mixer.
  2. Sift in the powdered sugar (and yes, sift! You don’t want clumps!) in 1 cup increments while continuing to beat the frosting.
  3. Add in a touch of vanilla extract and peppermint, and continue to cream together until smooth and fluffy.
  4. Frost your cake!

Then you can decorate your chocolate peppermint cake any way that you’d like! I do recommend that you apply a crumb coat to this cake for the first layer of frosting, as the cake can be delicate.

How to decorate a Christmas cake:

I recommend using about 3/4 cup to 1 cup of vegan frosting in between the layers, and what you’ll want to do is spread the frosting to go just beyond the edges of the layers.

That way, when you’re ready to frost the sides, it’s a a lot easier to get the frosting on the bottom edges of the chocolate peppermint cake! I also recommend sprinkling a little vegan peppermint crushed candy on top of each layer!

Now, I like to decorate my cakes, so I topped mine with a mini vegan gluten free gingerbread house and piped frosting onto vegan ice cream cones to create Christmas trees. I also sprinkled some crushed candy cane on top and on the sides.

Ingredients

Units Scale

Vegan Chocolate Peppermint Cake:

  • 350 grams unsweetened dairy free milk + 1 tsp acv, room temperature, mixed before the batter
  • 360 grams oat flour, sifted
  • 75 grams cocoa powder
  • 2 tbsp arrowroot powder
  • 1 1/2 tsp baking powder
  • 1 tsp baking soda
  • 375 grams unsweetened applesauce, room temperature

  • 34 cups powdered sugar
  • 1 tsp vanilla extract
  • 1 tsp food grade peppermint extract
  • Optional: crushed organic vegan peppermint candies

Instructions

Chocolate Peppermint Cake:

  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, sugar, vanilla extract, and peppermint extract. 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.

Vegan Peppermint Vanilla Frosting:

  2. Sift in the powdered sugar (and yes, sift! You don’t want clumps!) in 1 cup increments while continuing to beat the frosting.
  3. Add the vanilla extract and peppermint extract, and continue to beat until smooth and fluffy.
  4. Frost your cake!

Notes

Cocoa Powder: I recommend using Valhrona cocoa powder for a super rich and smooth chocolate cake. Please do not use cacao powder, as it doesn’t have enough acidity in it to create a good rise in the cake.
