Best Sweetener for Sugar Free Frosting

Now there is one thing you need to know about this frosting, so you do not have the surprise I did. When you are using a lot of swerve sweeter, it will leave you with this cooling sensation in your mouth as you eat the keto vanilla buttercream.

However, as odd as it might sound, I love this about the swerve! At first, I was thrown off with the unexpected cooling flavor that came from the keto frosting, that I didn’t know if I liked it or not. And then I couldn’t stop eating it. This can be off-putting to some people so you can substitute it for another type of confectioner artificial sweetener, like Lakanto Monkfruit 2:1 Powder Sugar Substitute. But I am going to be sticking with using Swerve confectioners in my keto buttercream frosting!

Sugar-Free Vanilla Buttercream Ingredients

Swerve. That was my first thought to replace the sugar. It totally worked and made one AMAZING keto Vanilla frosting! Do yourself the favor and buy the big 28 ounce bag of Swerve confectioners they now have on Amazon.

You will also need vanilla extract. I use my favorite homemade forever vanilla, but you can use store bought vanilla if that is what you have.

Instead of milk, like a traditional buttercream frosting recipe, this sugar free buttercream frosting uses heavy cream.

You will also need one of the most important parts of a buttercream frosting recipe. The butter! You want to use an unsalted butter, and if you are sticking with strict keto then you will want it to be a grassfed butter. However if you do not have grassfed butter, don’t stress it to much!

Place your butter and swerve in the bowl of your mixer. Mix them together on low speed until the sugar is incorporated.

Mix in the heavy cream and the vanilla extract.

Turn the mixer up to medium-high speed and continue mixing for 6-8 minutes until light and fluffy.
