This creamy keto buttercream frosting uses just a few low-carb ingredients.

Life is so much better with keto frosting!

Grab a spoon and dig into this glorious buttercream frosting that’s also KETO! Yep, you read that right, keto buttercream frosting!

You can have this delicious low-carb frosting as an occasional treat to satisfy sweet cravings when doing some keto-friendly baking.

using swerve to make frosting

The secret when making this keto frosting is to use a low-carb powdered sweetener such as Swerve confectioners. It does such a great job at making frosting as the taste and texture is so similar to powdered sugar.

You just need a few ingredients and a few minutes to whip up a batch of homemade creamy buttery frosting!

Hip tips for making the best keto buttercream frosting:

  • Use this recipe idea to frost a yummy keto cake, cupcakes, or cookies. It’s perfect for birthdays and special occasions so you can enjoy cake with frosting guilt-free!
  • Make sure to use softened and not melted butter. The best way to do this is to take the butter out of the fridge and let it soften on the counter first before starting this recipe. In a pinch, you can warm up a glass cup with hot water, dump it out, and place it upside down over the cold butter for a minute or so – that hack will do the trick, too!
  • Add a few drops of food coloring as desired for extra pizzazz. You can also skip the vanilla and add other extracts to flavor your frosting as desired depending on what type of cake you’re baking. Peppermint extract with green food coloring is pretty and tasty!
  • We suggest starting with 3/4 cup of powdered erythritol and then bumping it up to 1 cup according to desired taste and texture. Adding more will obviously give a sweeter taste and stiffer texture, so give it a taste while making.
  • Make this into a yummy chocolate frosting! Just add 1/4 cup of unsweetened cocoa powder to this recipe to make a delicious chocolate frosting.

Frosting is my favorite!

Are you a “more cake please” type of person or more of a “gimme all the frosting” fan? I can honestly say that a good buttercream frosting is the BEST! If you’d like to try out a yummy keto version, you won’t be disappointed with this one.

I think I love the chocolate even more than the vanilla, but I wouldn’t turn down either! Ha!

Is cream cheese more your jam? 

We also have a delicious keto cream cheese frosting that you’ve gotta try! I seriously can sit and eat it with a spoon like it’s a keto dessert – all on its own!

Check out what my teammate Jenna had to say about this frosting:

“This has such a great flavor and consistency! It was super easy to use with my new pastry bag! And my daughter was eating it by the spoonful!

I tried with ¾ cup of Swerve and that seems to be the magic number for me! It’s sweet like you imagine a frosting would be, but it still has the rich, creaminess of the butter! I know I have tried it with the full 1 cup and that’s good too in my opinion, but it is surely on the sweet side.”

    this was delish!

      So glad you liked it! Thanks for the feedback!

    Hi, I have a question. How well does the frosting hold up if I frost cupcakes the night before a bridal shower? If so, will the frosting hold up unrefrigerated, or should I refrigerate it?

    • Lina D (Hip2Save Sidekick)

      Hmm it may depend on the temp of room. If its not warm i think it would do fine out one night.

    I’m not sure what I’m doing wrong, anytime I try to make it it always separates and won’t beat into a fluffy hoogenous mixture. When I Google what is wrong it says it’s the mixing of the water-based vanilla with the oil in the butter. It works a little bit better when I use whipping cream but sometimes I just have butter on hand.

    • Jennifer (Hip Sidekick)

      Your butter should be softened but not too soft. You could try leaving it a little colder when you make the frosting. Also, make sure you are using real butter and not spread. 🤗
