Step 1

Sift together the sugar alternative and cornstarch in a medium bowl. Set this aside.

Step 2

In a mixing bowl, cream together the cream cheese and butter. It should take a few minutes until this mixture reaches a desired creamy texture. Hence, using a stand mixer is desired.

Step 3

When your cream cheese and butter have reached that desired creamy texture, slowly mix in the vanilla and the contents of the first bowl by hand. I like to add half of the sugar alternative/cornstarch at a time, stirring between additions.

Step 4

When this frosting reaches a spreadable texture that you need, then it is ready to use. Refrigerate this frosting if not using immediately and allow it to become soft when you are ready to use it. Items with this frosting on them should be refrigerated as well.
