  • Topping:
  • 1-1/3 cup chocolate chips

  • Spread in a greased 15 x 10 x 1" pan.
  • Bake at 350F for 15-18 minutes.
  • Sprinkle marshmallows evenly over cake; return to oven for 2-3 minutes.
  • Using a knife dipped in water, spread the melted marshmallows evenly over cake.
  • Cool. (I did not spread them, when I took them out of the oven they seemed fine the way they were. )
  • For topping, combine chocolate chips, peanut butter and butter in a small saucepan.
  • Cook over low heat, stirring constantly, until melted and well blended.
  • Remove from heat; stir in cereal.
  • Immediately spread over bars.
  • Chill.

When I saw these on Good Eats 'n Treats I knew I had to try them. They are worth making. Next time I will add more peanut butter to them.
