2 cups- Sugar
3/4 cup- Sour Cream
1/2 cup- butter
12 oz.- white chocolate morsels

Combine sugar, sour cream, and butter in a saucepan. Bring to full rolling boil, stirring constantly. Continue boiling for 7 minutes over medium heat, stirring constantly. Remove from heat; stir in white chocolate until melted. Add marshmallow creme and walnuts, beat until blended.
