One of my wife's sickening-sweet-but-it's-like-crack recipes.
Produces: 20 cups
1 1/8 cup butter
4 1/2 cup semi sweet chocolate chips.
1 1/2 cup peanut butter
2 lbs powdered sugar
20 cups rice crispies or chex cereal
Melt all but sugar in microwave. Dump the cereal in plastic bags (double layered, trust us on this), add chocolate, mix. Once all coated, add sugar "a large bit at a time", so that you're coating bits of it. Keep adding until no longer sticky.
