Creating a keto buttercream frosting can’t get much easier than this. With just a couple of ingredients, a mixing bowl and a whisk, you’ll get yourself the fluffiest keto frosting for your yummy keto-friendly cupcakes and cakes.
Starting with a simple and no-fail vanilla flavor, this is definitely among the most versatile of recipes. This keto buttercream frosting is a blank canvas for other exciting flavors like orange, maple or almond. It will make the perfect keto frosting no matter what fluffy cake base you put it on.
Taste Equals Nutrition
As this is a very simple recipe with just a handful of ingredients, it is fair to say that procuring the right ingredients is a must. Using grass-fed butter is essential because aside from making this frosting delicious, its nutritional value is vastly different from regular butter.
Speaking of the nutritional profile of grass-fed butter, it is made up of butyrate, which is an anti-inflammatory fatty acid. Aside from that, it also has vitamin K2 that can de-calcify the arteries. Now aren’t those reasons enough to splurge on butter?
Sweet But Not Too Sweet
Now speaking of taste, frosting isn’t frosting if it isn’t sweet, however, you don’t want something that is so sweet that it overpowers your baked good. Also, you’ll want something that is sweet enough to complement and improve the overall flavor of your cake or cupcakes.
If you’ve been on a keto diet for some time now, you’ll know that there are actually a number of options for sweeteners. Yes, you can use whatever sweetener your tastebuds are accustomed to already, but remember that for this keto buttercream recipe, it must come in powdered form. For this recipe, powdered Lankanto is my sweeter of choice. A hint of sugar-free vanilla extract is also ideal for some added complexity.
More Keto Buttercream Frosting, More Options
Like I mentioned earlier, this recipe is a perfect foundation for other flavored frostings. This recipe is so easy to make with only three ingredients max that it may become your go-to frosting.
As for flavoring, yes I mentioned orange, maple and almond but I won’t let you stop there. That’s the beauty of having such a simple, yet delicious vanilla-based dessert recipe especially if you have a sweet tooth. Just let your imagination or mood run the show if you must! There are so many frosting flavors to choose from and so many baked goods that need a scoop or two of icing.
Just always be sure you’re still using keto-friendly ingredients when flavoring your creamy frosting. The sky’s the limit with what you can create using this yummy yet healthy frosting recipe.

Tips & Notes:
- The butter must be at room temperature and soft - If too cold, the buttercream won’t cream.
- Sweetener choice - Use powdered and see my comments above on sweetness.
- Pipe whilst fresh - If you need to store the frosting, place it in an airtight Tupperware in the fridge for up to 5 days and allow to come to room temperature naturally before piping. Don’t leave the buttercream out in the open air overnight and then try and pipe, it will curdle… tried and tested!
