Does anyone have a recipe for Cheesecake Buttercream?
I have never heard of cheesecake buttercream. Maybe cream cheese buttercream? Cheese cake is made from cream cheese so that would make sense. There are several cream cheese buttercream recipes in the recipes section here on CC. Just click on the tab at the top of the page which says recipes.
I've never tried it, but I know that "Loranne Oils" makes a cheesecake flavor. You could try adding that to your recipe in place of any other flavors you normally use (instead of vanilla, almond, etc.).
