  • electric mixer


  • 140 grams unsalted grass-fed butter room temperature
  • 140 grams cream cheese room temperature
  • pinch kosher salt
  • ¼-½ cup Natvia sweetener, or erythritol or other sweeteners of your choice powdered
  • 2 tsp vanilla extract
  • 2-3 tbsp cocoa powder


  • In a large bowl, add the butter and cream cheese. Use an electric mixer and beat until evenly combined, about 2 minutes.
  • Add the salt. Then gradually add the sweetener, one tablespoon at a time. Continue to beat the mixture until pale and fluffy, about 8-10 minutes. Scrap the sides and bottom of the bowl as needed. Also, feel free to adjust sweetness depending on your preference.
  • Add vanilla extract and beat until all the ingredients are fully incorporated.
  • At this stage, you have created Keto Vanilla Buttercream Frosting. But if you are making a chocolate version, you can sift the cocoa powder, one tablespoon at a time into the bowl. Beat until fully combined. This recipe is enough to frost roughly 12 cupcakes.


  • You can pretty much use whatever sweetener you like. I just prefer Natvia sweeteners in my baking. Just make sure that the sweetener is powdered. It is easy to do it yourself, just whizz it up or process it in a blender and your regular sweetener will turn into powdered. Easy! But wait, don't open the lid yet! Wait for a few moments for the powder dust to settle back down. 
  • Or you can always grab a bag of powdered sweetener. No-fuss!
  • Make sure that the butter and cream cheese are at room temperature before mixing.
