A low-carb vanilla buttercream frosting is a must as a basic, and once you get this, you can play around with adding flavors.

Low Carb Vanilla Buttercream Frosting

Since I’ve started a home based keto friendly bakery, I’ve had to make sure my frostings are perfect, and make sure the basic recipes that people love, taste like they always remember.

I started a home keto bakery quite by accident, and it’s taking off. I currently sell small cakes like you see below. You can see more on my bakery page.

What is the best sweetener for low carb buttercream?

I use Swerve. They make a great confectioner’s sweetener along with a granular sweetener. Read here why I love this product and how I use it.

What’s the difference between frosting and icing?

Frosting is made with butter and confectioner’s sugar, whereas icing is more of a glaze and doesn’t have butter. Icing is thinner, sweeter and glossier. Icing could be made with heavy cream, but it could also be made with milk water or juice.

Frosting is thick and most often made with butter, cream cheese or a combination of both, along with heavy cream, and that’s exactly how this buttercream is made.

I tend to add a touch of cream cheese to my frostings, but I don’t want them to taste like cream cheese unless they are a bonafide cream cheese frosting like this low-carb cream cheese frosting.

How do you make a low-carb vanilla buttercream frosting?

This low-carb vanilla buttercream frosting is made with Swerve’s confectioner’s sugar, butter, a small amount of cream cheese, pure vanilla extract or vanilla paste and heavy cream. It took a while for me to get it right (for me). You may add more of this or that, but I think one of the keys is vanilla paste. I like to see those little specks of vanilla dispersed through the frosting.

You all loved my low-carb chocolate buttercream frosting, and you will love this just as much. If you’re following a low-carb, sugar free life style, this makes layered cake possible and scrumptious. This recipe is for a one layer cake or 12 cupcakes, so double it for a double layer cake.

Like all my frostings, low-carb vanilla buttercream frosting freezes exceptionally well.

The question now is what cake recipes do I choose to use low carb vanilla buttercream frosting with?

This double layer cake went to a bakery customer. I used my small offset spatula to make this simple, classic design.

This is one of the ways my bakery decorates the celebration cake. Bakery information here.

Make Rosettes

Hold piping bag perpendicular (no angle) , starting in center, pipe starting from an inch above cake, down and then in circle, slightly overlapping. Practice on a plate first, then put that practice back in the bag. One thing we sometimes do is the same design on the first layer. If we don’t like it, that layer becomes the center. If we love it, it becomes the top.

Ingredients

Instructions

  • The key to this frosting is beating the butter for five full minutes.
  • Once the butter is whipped, add the cream cheese.
  • Add the vanilla paste. If I want a serious vanilla taste, I'll add more vanilla paste.
  • Add salt.
  • Add heavy cream, if needed. If you are going to pipe scoop out with large spoon, hold sideways over bowl. Frosting should plop back into bowl in about a second or two. If it doesn't you will need to add a little heavy cream.
  • Refrigerate or freeze until ready to use. If you take out from refrigerator, give it a chance to come down to room temperature.
