Course Cake, Dessert


  • 1 1/4 cup Xylitol
  • 1/4 cup Water
  • 5 Egg Whites, room temperature
  • 1/2 teaspoon Cream of Tartar
  • 16 oz Cream Cheese, softened
  • 1 1/2 cups Unsalted Butter, softened
  • 2 teaspoons Vanilla Extract (Clear)


  1. If you only have 1 mixing bowl for an electric mixer, do step 6 first and then set aside for later.
  2. In a small saucepan, heat water and 1 cup xylitol over medium heat. Continue heating until the xylitol has reached between 240 and 250 degrees F. Be careful. Xylitol will be extremely hot!
  3. While the xylitol is heating, begin whipping egg whites in an electric mixer with a whisk attachment. When eggs are frothy, add the cream of tartar. When soft peaks form, add the remaining 1/4 cup of xylitol. Continue to whip until stiff peaks form. The goal is to have the xylitol reach 245 degrees F at the same time that the eggs have reached stiff peaks.
  4. With the electric mixer on low speed, gently add the xylitol in a thin stream into the eggs. Be careful not to touch the whisk or the sides of the bowl with the xylitol.
  5. Continue whisking on high speed until the frosting has cooled, about 10 minutes. The mixing bowl should be roughly room temperature or slightly warmer.
  6. In a separate mixing bowl, combine cream cheese and 1 cup of butter. Beat with an electric mixer with a paddle attachment until well blended.
  7. Return the egg and xylitol to the stand mixer with a paddle attachment and turn the mixer on low. Add the cream cheese and butter blend 1 tablespoon at a time. Once added, begin adding butter 1 tablespoon at a time until either the buttercream has smoothed out or the butter is gone. Continue to beat the buttercream until the frosting is smooth and not runny.
  8. Mix in the vanilla extract. If buttercream is too soft, refrigerate until it has stiffened. Re-whip before using.
  9. For best results, use immediately. Frosting may be stored in the refrigerator for later use for up to 5 days. Re-whip before using.
