World's Best Peanut Butter Frosting

I love peanut butter.  Hubby is a little more particular, but he likes this.  Please note - the recipe does not say peanut butter.  IT DOES MAKE A DIFFERENCE!!!!  This will frost 3 layers nicely.  Halve recipe for 9 x13.

1 Cup Butter, Softened
2 Cups Creamy Jif
8 Cups Powdered Sugar
3/4 Cup Heavy Whipping Cream - may not need all of it

Whip the butter until very light in color.  Add Peanut Butter, whip again.  Add 1/4 cup Whipping Cream, mix well.  Add 1/4 cup Whipping Cream, mix well.  Add the powdered sugar, 1 cup at a time, mixing between each addition.  Once all sugar is incorporated, add enough remaining cream to be the consistency you prefer.  Spread over cooled cake layers and enjoy.
