Melt 4 Snickers or Mars bars (other candy bars would work too) with 1/4 cup butter. Add 2 cups crispy rice cereal.
Melt 1 small package chocolate chips with 1/4 cup butter.
Spread rice mixture in 8" x 8" pan. Let cool a bit. Top with chocolate mixture. Cool to room temperature, if you put it in the fridge it gets too hard.
