You should try to make it yourself. All you need is three simple ingredients: 6 cups of powdered sugar, 2 boxes of cream cheese, and 2 sticks of butter.
In a mixing bowl, add butter and cream cheese together and whip on medium high speed until well blended and fluffy.
That's pretty much it! It's so quick and easy to make. You can actually minimize the ingredients or if you have leftovers, just store them in the freezer for future use.
