Ingredients in Keto Buttercream
You may have noticed that traditional frosting recipes are pretty much the opposite of keto-friendly. The main ingredient is sugar!
Luckily, it’s not too hard to make keto-friendly buttercream — all you need are the right ingredients. This particular buttercream recipe is made with butter, flavorings, and a low-carb swap for normal powdered sugar.
Sweetener
You can use whichever low-carb sweetener you like — as long as it’s powdered. I prefer to use powdered erythritol sweetener in this recipe — and choose Swerve Confectioner’s brand because it is so convenient.
If the sweetener you have is not powdered, you can blitz it in a completely dry blender until it becomes powdered.
Vanilla
If you are making vanilla buttercream, why not splurge on the good stuff! You absolutely can’t beat the flavor of Nielsen-Massey Pure Vanilla Bean Paste. I love the classic rich vanilla bean taste. Plus, I love that the paste contains real vanilla bean flecks. 1 teaspoon of paste is the equivalent of 1 tsp of extract, so you can use it in all your baking recipes.
Cocoa Powder
You can also flavor this buttercream with cocoa powder. Your chocolate buttercream will be richer and more flavor all if you skip the low-fat supermarket variety cocoa powders in favor of a higher-fat, upgraded version like this one. So good! It’s Barry Callebaut brand packaged by Gerbs, so know it’s going to be delicious.
Other Extracts
Just like you’d use vanilla paste or extract, you can use any other flavor of extract to customize this keto frosting. Maple frosting would go great with this keto pumpkin bread. A lot of people like lemon frosting on gingerbread. And why not banana frosting to amp up the flavor on keto banana bread?
How to Make Keto Buttercream
The process for making keto buttercream couldn’t be simpler, but you will need an electric mixer for the best results. You can use a stand mixer, but a handheld mixer works well too.
Start by beating the room temperature butter and powdered sweetener together until the mixture is fluffy. This will be easy to do, as long as you make sure the butter is at room temperature first. Then, beat in the vanilla extract — or whatever other flavorings you choose to use.
Finally, beat in some heavy cream to thin out the frosting to a creamy consistency. You can adjust the consistency to your liking. If you are using it to stack a layered cake, you may want a bit firmer than for frosting cupcakes, for instance.
Flavor Variations for Keto Buttercream
Like we talked about before, the sky is the limit when it comes to flavoring your keto frosting. Let your creativity run wild — and don’t forget to leave a comment telling me about your combinations!
How to Store Keto Buttercream
You can store keto frosting in the refrigerator for up to five days, as long as you store it very tightly covered. Let it come to room temperature before using it. And you may want to whip it again to make sure it’s still fluffy.
Likewise, you can also freeze it. Let it thaw in the fridge, and them come up to room temperature on the counter before using it.
