Mix together and press into an ungreased 9 x 13 inch pan. Bake at 350 degrees for 12 to 18 minutes (or until cake is done) may vary in different ovens. Once baked and while hot put 3 cups of miniature marshmallows on top. Combine:

Heat until smooth, stirring constantly. Add 2 cups of Rice Krispies and 2 cups salted peanuts. Pour over the marshmallow topped cake. Let stand and cool; cut into bars.
