Keto Chocolate Cupcakes, Keto Peppermint Frosting

This is big seller at Christmas time in my keto grain free bakery

How do you make sugar free keto peppermint frosting?

Swerve confectioner’s sweetener, butter, peppermint extract. 

Swerve, a powdered erythritol,  makes it’s super easy to make beautiful creamy sugar free frosting, that is very keto friendly. They make a granulated and confectioner’s version. Sugar free eating couldn’t be easier or more delicious. 

I took notes from my keto vanilla buttercream and replaced most of the vanilla extract with peppermint extract. Read here why I love Swerve. 

Making Keto Peppermint Buttercream Frosting

My rule of thumb for the perfect keto buttercream is 1/2 cup Swerve confectioner’s sweetener to 1/2 cup butter. 

Since it’s December, there is a challenge to face when it comes to making buttercream. The butter, at room temperature, is too hard. 

What is the perfect butter temperature for making buttercream frosting?

Butter should be between 65 and 68 degrees and be able to bend with flexibility. I will sit the butter on top of my stove. You will need to be careful, however, that the butter isn’t too soft. If it’s too hard or too soft, you will never be able to get it to that perfect smooth, creamy, able to pipe consistency. 

Sugar Free Sprinkles

The Sprinkle Company makes sugar free sprinkles in several colors. I was lucky enough to have been gifted these Christmas sugar sprinkles just in time.

Keto Chocolate Cupcakes

My recipe for keto chocolate cupcakes is delicious, kitchen tested and sold weekly in my keto bakery. I think it’s perfect. I use almond flour and coconut flour, cacao powder, Swerve, and coffee. The texture is a sponge cake that rivals any wheat-based sponge.

Peppermint Frosting

  • Whip together butter and cream cheese until completely smooth. You may need to whip these in separate bowls. Make sure butter is softened, but not melted.
  • Add peppermint extract.
  • Add heavy cream if you need to. Sometimes I add a tablespoon of boiling water instead to get a frosting easy to pipe.
  • Use large round tip in piping bag to apply frosting.


In place of the coffee, you can use more buttermilk.
There is a different chocolate cake recipe here using coconut flour which was posted originally. I have improved the recipe. If you want the original find it at bottom of post.
If you don't think the frosting is sweet enough, add up to 1/4 cup more.
