  • Electric mixer or Stand mixer



  • Add the butter to a large bowl and mix using an electric mixer.
  • Beat the butter on the medium speed for 3 minutes until butter is lighter in color.
  • Alternatively, you can use a stand mixer with the paddle attachment.
  • Add in the powdered sweetner and mix on low speed for one minute.
  • Then, increase the speed to medium and continue mixing for another minute or two.
  • Add in the heavy cream, vanilla extract and salt.
  • Continue to mix using medium speed until the frosting is all combined.
  • Will frost about a dozen cupcakes.


  • Want a chocolate buttercream frosting?  Simply add in 1/2 of sifted cocoa powder when you add in the powdered sweetener.  If you frosting becomes too thick, add in a little more heavy cream until it becomes the consistency you like.
  • Lakanto Powdered Sweetener: This is my favorite brand of low carb sweetener and you can find a link to the product below the recipe card.  If you want to Use Swerve Powdered Sweetener, you would need to use a little less.  Start with half the amount and add more if you think it needs to be sweeter.
