Who doesn’t love a good dollop of frosting on their cupcakes, tea cakes, or muffins? It even takes pancakes, waffles, and French crepes to another level. The problem is standard frostings contain SO much sugar. According to the USDA, a two-tablespoon serving of buttercream frosting has almost 14 grams of sugar. That makes it a no-go for anyone following a low carb diet.

What if I told you that you could enjoy your favorite frosting flavors with almost ZERO carbs? Everyone has to learn how to make my keto buttercream frosting recipe. Make it in plain, chocolate, or lemon flavor, or customize the simple recipe to make endless flavors.

I use this keto buttercream frosting to elevate so many different recipes. It goes perfectly with my lemon poppyseed cupcakes, chocolate cupcakes, and coconut flour crepes.

As for the keto chocolate buttercream frosting, I like to top mine with cocoa powder, grated chocolate, and a few dots of sugar-free chocolate syrup when I feel fancy.

Keto Buttercream Frosting Ingredients

This buttercream frosting recipe only needs 4 simple ingredients and salt to make.

• Butter - Start with the highest quality butter you can get, as it’s the main ingredient here and will make a lot of difference. Make sure it's unsalted and softened at room temperature.
• Erythritol - I use powdered Erythritol as the sweetener. Substitute for another sugar-free sweetener, like monk fruit. Make sure it's powdered because that will keep the frosting nice and smooth without any gritty texture.
• Vanilla extract- Like butter, use a high-quality pure vanilla extract for the best flavor.
• Sea salt - A pinch of salt to help balance out all the flavors.

For Basic Buttercream Frosting

• Heavy cream - Makes the plain buttercream frosting the perfect creamy consistency. Substitute for almond milk or coconut milk.

For Chocolate Buttercream Frosting

• Cocoa powder - You'll need unsweetened and sugar-free cocoa powder for the chocolate flavor. I recommend using Dutch-processed cocoa because it's not as bitter.

For Lemon Buttercream Frosting

• Lemon - The lemon buttercream needs about one tablespoon of lemon juice and zest.

How To Make Keto Buttercream Frosting

• In a mixing bowl, add the Erythritol and softened butter.

• Beat with an electric mixer for 1 to 2 minutes until fluffy.

• Add the vanilla extract, heavy cream/cocoa powder/lemon juice and zest, and sea salt. Beat for another minute at medium speed.

Storage Instructions

This frosting can be stored short, mid, and long term, making it even more versatile.

• Room temperature: Buttercream frosting used on baking like cupcakes or muffins can be kept at room temperature for up to 2 days.

• Refrigerated: To store leftover or unused frosting, keep it in an airtight container in the fridge. It will keep for one to two weeks.

• Frozen: Buttercream freezes great for long-term storage. Place it in a freezer-safe bag and remove as much air as possible. It will keep for up to three months. When you're ready to use it, place it in the fridge to thaw overnight, and then let it reach room temperature before you use it.
