Tips and Variations

  • Storage - Store this keto buttercream frosting in a sealed container in the fridge for up to 3 days. Store in the freezer in the same type of container for up to 2 months.
  • Reheating - Let the keto frosting recipe thaw on its own if being used from the freezer, and do not try to force heat it. If using from the fridge, let it sit for about 30 minutes before attempting to frost your dessert.
  • Add other extracts - If you want to mix up the flavors, replace the vanilla extract with other extract flavors such as orange, lemon, chocolate, etc. There are countless extract flavors to choose from. Everyone loves keto chocolate frosting. Watch out for the ones with alcohol in them.
  • Add colors - Use food coloring to make various colors of your frosting. This allows you to match color schemes for certain events.
  • Use clear vanilla - Clear vanilla allows the very slight bit of brown from the extract to be removed. This means it will be a truer white. 
  • Add cream cheese to make a low carb cream cheese frosting - Replace one of the sticks of butter with softened cream cheese for a keto cream cheese frosting. 
  • Add spices - You can add cinnamon, nutmeg, allspice, pumpkin pie spice, etc. for more flavor! These work great for muffins and similarly flavored cupcakes. 
  • Use it as a dip - This frosting would be delicious with fruits, keto graham crackers, or similar items. This option would be a great time to add in the cream cheese for an even better dip flavor or a perfect topping.

Common Questions About Keto Frosting

Which is Better Frosting or Icing?

In regards to flavor, that really comes down to personal preference. They both have their places in the baking world. Frosting is a much lighter and fluffier condiment used as a topping or a filling (think cake). Frosting is much thicker too and more overpowering as far as flavor goes. Icing is thin and used as a light, sweet coating on recipes such as glazed donuts. So, both aren’t usually used interchangeably and can’t really be compared in such a manner. You can use a piping bag to add this low carb frosting. It really depends on right consistency and personal preference for this traditional frosting.

What Can I Use Instead of Frosting?

There are a lot of things you can use instead of frosting! Some of the most popular options are whipped cream, powdered sugar, icing, and even things like caramel sauce and hot fudge. You could also go the “naked” route like I do. It’s where you make the recipe to be great all on its own but is perfect for keto cupcakes, keto carrot cake or any of your favorite keto cake recipes.
