I shared this beautiful cake for the holidays last year after testing it multiple times to get the perfect texture and flavor. I immediately texted a photo to my team, and they were basically left speechless.
I mean, just LOOK at that fudgy cake with the most tender crumb and the fluffiest buttercream!
This is my gorgeous chocolate peppermint cake with a luxurious peppermint buttercream frosting (and plenty of crushed candy canes for good measure). She’s festive, she’s cute, and she’s a little “snacking cake” AKA my favorite type to bake when I don’t feel like baking a bunch of layers. OH, and she’s gluten-free, too! So easy to make and perfect for your holiday table. Trust me, after one bite everyone will be asking for this recipe!


Everything you’ll need to make this chocolate peppermint cake
This gluten-free mint chocolate cake is deliciously moist and fudgy, and SO easy to make with simple ingredients:
- Flour: we’re using a mix of fine blanched almond flour and oat flour to keep the cake gluten-free.
- Cacao powder: I love baking with cacao powder because it adds such a rich chocolate flavor. You can also use unsweetened cocoa powder.
- Yogurt: plain Greek yogurt gives this cake extra moisture.
- Eggs: you’ll need 3 eggs to bake the cake up properly.
- Butter: we’re also adding some melted salted butter into the cake batter for even more fudgy texture. You’ll need butter for the peppermint buttercream as well!
- Sweeteners: we’re naturally sweetening the cake itself with pure maple syrup and coconut sugar.
- Flavor boosters: we’re adding both vanilla extract AND peppermint extract to bring out the sweetness and the perfect mint flavor.
- Baking staples: you’ll need both baking powder and baking soda, plus a little salt.
- For the peppermint buttercream: I’m obsessed with how this frosting turned out. It’s made with salted butter, powdered sugar, vanilla and peppermint extracts, and a tiny bit of milk. I like to add a little red or pink natural food coloring to make the frosting pink, and then don’t forget the crushed up candy canes to decorate!


Easy dairy-free and vegan swaps
Yes, you can make this chocolate peppermint cake dairy-free and/or vegan! Simply use:
- A dairy-free yogurt (I suggest siggi’s plant based vanilla cups)
- Coconut oil or vegan butter in the cake itself (I recommend Miyoko’s salted vegan butter)
- 3 flax eggs (if making it vegan)
- And vegan butter in the frosting


Can I use different flours?
Unfortunately, no, I cannot recommend a substitute for the almond flour and oat flour in this recipe, so swap at your own risk!
How to make the best chocolate peppermint cake
- Whisk the dry ingredients. Whisk together all of your dry ingredients in a large bowl until well combined.
- Mix the wet ingredients. Mix the wet ingredients EXCEPT the butter in a separate large bowl until smooth.
- Combine the batter. Add the dry ingredients to the wet and mix until combined and smooth, THEN stir in the melted butter.
- Bake it up. Pour the batter into a prepared 8×8 inch baking pan, then bake until a tester comes out clean!
- Make the frosting. Use an electric mixer or hand mixer to whip the softened butter. Add the powdered sugar, extracts, and food coloring (if using), and beat slowly, then increase speed to high until the frosting is fluffy. Mix in some milk to thin it out a bit if you’d like.
- Frost, slice & devour. Spread the frosting onto your cooled cake, sprinkle crushed candy canes, slice, and serve!


The importance of weighing ingredients
I test all of my baking recipes by weighing the ingredients, which is the best, most accurate way to ensure that your baked good turns out perfectly! If you don’t already, grab an affordable kitchen scale and get into the practice of weighing. It makes such a difference, and will save you clean-up time!
Can I make cupcakes?
Yes! Simply divide the batter into a standard cupcake pan lined with cupcake liners, and spray the insides with nonstick cooking spray. Bake for about 15-18 minutes until a tester comes out clean. Cool the cupcakes completely before frosting and decorating.


Try a double chocolate version
The peppermint buttercream frosting is truly exceptional, but if you’re a big chocolate lover, try topping the cake with this perfect chocolate buttercream frosting.

Storing & freezing tips
- To store: I recommend storing this chocolate peppermint cake in airtight containers in the refrigerator for up to 5 days.
- To freeze: let the cake cool and then wrap it well without the frosting in plastic wrap and aluminum foil. Place the full cake in an airtight container or zip-top freezer bag. To serve it, thaw the cake in the refrigerator overnight, then let the cake come to room temp before adding the frosting and serving it.

Instructions
Preheat the oven to 350 degrees F. Line an 8×8 inch square baking dish with parchment paper or generously spray with nonstick cooking spray.
Mix the dry ingredients: In a large bowl, add the almond flour, oat flour, cacao powder, baking powder, baking soda and salt. Mix until well combined and smooth.
Mix the wet ingredients: In a separate large bowl, whisk together the yogurt, eggs, maple syrup, coconut sugar, vanilla and peppermint extracts until smooth and well combined. DO NOT ADD MELTED BUTTER YET.
Combine the wet and dry ingredients: Add the dry ingredients to the wet ingredients and mix with a wooden spoon until well combined and smooth. Add in the melted butter and stir again until the butter is well incorporated into the batter.
Bake the cake: Pour the batter into the prepared pan and smooth the top. Bake for 23 to 28 minutes until a tester comes out clean. Allow the cake to cool completely before frosting.
Make the frosting: In the bowl of an electric mixer, add the softened butter and whip on high until light and fluffy (alternatively you can use a hand-mixer). Add powdered sugar vanilla and peppermint extracts (and 1 to 2 drops of food coloring if desired!) and beat slowly at first, then increase speed to high and beat for 1 to 2 minutes until fluffy. Add milk to thin the frosting out and beat again for 30 seconds until fluffy.
Frost the cake and top: Add frosting to the top of the cake and evenly spread to the edges. Sprinkle crushed candy canes all over the top. Cut into 12 or 16 slices and enjoy!
