This keto buttercream frosting recipe is luscious, creamy, and absolutely decadent. You can use it to top off your favorite cakes and cupcakes or frost cookies if you’d like. The recipe is gluten free, dairy free, refined sugar free, paleo, and keto.
I’m so excited that I’m finally sharing this keto buttercream frosting recipe with you. It has been a long time coming, as I’ve probably made it over 10 times at this point.
It was the buttercream I topped off Sophie’s first birthday smash cake with, and it’s my go-to for any and all cupcakes that I make.
Why is this dairy free buttercream frosting recipe great?
- It is incredibly easy to make. Simply add the ingredients to a stand mixer!
- Customizable: if you want it a bit thicker or thinner, simply change the amount of coconut oil you add.
- Store it in the freezer in an airtight container for up to 3 months for later use.
- Nobody will know it is better for you. It tastes like the real deal, and the texture is spot on.
- It checks all of the boxes as it is dairy free, vegan, paleo, and keto.
What ingredients do you need?
It’s really simple. I wouldn’t recommend making any substitutions however.
The only substitution that can be made is using powdered sugar instead of erythritol / Swerve. You would need to use 3/4 cup of powdered sugar.
Other than that, here is what you need:
- Palm shortening
- Powdered erythritol or Swerve
- Arrowroot flour
- Coconut flour
- Pure vanilla extract
- Coconut oil
What’s wonderful about this frosting recipe is how finicky it isn’t. You can also customize the texture / thickness to your liking.
Simply slowly drizzle in that melted coconut oil at the end. I prefer it with about 3 tablespoons of melted oil, but depending on what you are using it for, you may want to add a little more or less.
I’ve seen some fabulous cream cheese based, keto recipes for buttercream frosting around the web, too. Although the first one is not dairy free, it look fabulous if that’s what you’re into.
Some of my go-to’s include:
Low carb sweeteners
I don’t recommend substituting the arrowroot flour with anything but tapioca flour.
Be sure to slowly drizzle in the oil and make sure it is completely melted but not scorching hot.
How to make keto buttercream frosting
Mix the shortening & sugar: In a stand mixer with a paddle attachment or using a large bowl and an electric hand mixer, add in palm shortening and powdered sugar. Mix on medium high until smooth throughout.
Add the rest of the ingredients except for the coconut oil. Mix for about 1 minute.
Slowly drizzle in coconut oil while turning the mixing speed up to high. You may need a tablespoon more to reach your desired consistency depending on the other brands of products you use, but I got the perfect texture with only 3 tablespoons.
Remove from the mixer and give everything a nice stir.
What can you eat this buttercream frosting with?
ALL OF THE THINGS. But in all honesty, here is what I recommend:
- Use it as a frosting on cakes or cupcakes
- Put it in between two chocolate chip cookies and make a sandwich… oh my gosh!
- Use it as a vanilla frosting on top of keto chocolate cake.
- Fruit. Oh my gosh, heavenly with fresh strawberries especially!
- Eat it with a spoon. Trust me 😉
