These easy no bake bars are the ultimate salty/sweet combo!


  • 2 cups finely crushed Ritz Crackers (approximately 2 sleeves)
  • 1/2 cup butter, melted
  • 1/4 cup granulated sugar
  • 2 cups Marshmallow Fluff
  • 1 cup semi-sweet chocolate chips
  • 1 cup crunchy peanut butter
  • 2 cups Rice Krispies


  1. Line a 9×9 pan with foil and spray lightly with cooking spray. Set this aside.
  2. In a large bowl combine the crushed crackers, butter and sugar. Firmly press this mixture evenly into the prepared pan and chill it for 30 minutes.
  3. When the crust is chilled, remove it from the refrigerator and spread the Fluff evenly on top. Place this back in the refrigerator for 15-20 minutes.
  4. In a large microwave safe bowl combine the chocolate chips and the peanut butter. Place this in the microwave on full power for 1 minute. Stir the mixture until the chocolate is melted. If 1 minute was not long enough heat for an additional 20 seconds, or until the chocolate is melted.
  5. Stir the Rice Krispie cereal into the chocolate mixture evenly and spread on top of the Fluff layer.
  6. Place back in the refrigerator until the chocolate is set.
  7. Cut into squares only when ready to serve.


Keep this in the refrigerator, airtight. As it comes up to room temperature the Fluff gets gooey, which is delicious, but a little messy!

You can sub in 1 1/2 cups of mini marshmallows for the Fluff to keep these less gooey! This is a great option if you are serving these on a platter for any period of time.
