Peanut Butter Rice Krispy Bars

I often bring these to the beach and picnics, referring to them as crack bars. Make them and you'll see why.

10oz bag of Marshmallows
4 tbs Butter
1/2c Peanut Butter
2c Trail Mix
5c Crispy Rice Cereal

Over a medium low heat, melt the butter, marshmallows and peanut better in a large pot, constantly stirring. Once combined turn off the heat and stir in Trail mix and cereal. Press into a pan to set. Cut into squares once firm.
