1 box yellow cake mix
1 egg
1/3 c. soft butter
3 c. miniature marshmallows

Preheat oven to 350 degrees. In large bowl, mix base ingredients, except marshmallows. Press in bottom of 9 x 13 inch pan sprayed with Pam. Bake 12 to 16 minutes or until lightly golden brown. Immediately spread on marshmallows. Return to the oven for 1-2 minutes or until marshmallows begin to melt. Spread evenly over base. Let cool while topping is prepared.

TOPPING:

2/3 c. corn syrup
2 tsp. vanilla
2 c. Rice Krispies
1/4 c. butter
2 c. peanut butter chips
1 c. chopped salted peanuts

In pan, heat corn syrup, butter, vanilla, and chips; stir until chips melt (this can also be done in a microwave). Stir well. Remove from heat. Add cereal and nuts, stirring to blend. Immediately spoon over marshmallows. Chill. Cut into bars. Makes 36 bars - taste like "Payday Candy Bars".
