In a large bowl, combine pretzels, cereal, m&ms, and chocolate chips. Set aside.

In a large sauce pan, melt together the butter and peanut butter over low heat. Stir in the marshmallows and continue to cook over low heat until the marshmallows are melted.Pour over the snack mix and toss to coat.

Press mixture into a 9×13 pan lined with waxed or parchment paper. Firmly press mixture together to ensure that the bars stick together when they have cooled. Refrigerate until the mixture is completely cool and firm. Cut into bars and serve.
