Chocolate bonbons

A holiday treat from my BIL's family.

2 c. peanut butter
1/2 c. butter
1 lb (4.5 c) confectioners sugar
3 c. Rice Krispies
4 6 oz packages semi sweet chocolate chips

Melt peanut butter and butter in a saucepan over low heat.
Combine sugar and cereal in a large bowl.
Pour peanut butter mixture over the cereal and mix well.
Shape into balls and let sit until cooled, preferably overnight.
Dip the bonbons in melted chocolate and let cool again.
