Chocolate Peanut Butter Balls

1 lb powder sugar
2 1/4 cups peanut butter
1 cup butter (softened)
3 1/2 cups Rice Krispies
Chocolate chips

Mix the first three then add the Rice Krispies. Roll into balls & freeze before dipping (so they don't come apart). We use milk chocolate chips, but you could use whatever you want. Best if you leave in the the freezer or in the fridge.
