Salted Peanut Bars

You’ll never look at Rice Krispies Treats the same way again after trying these nutty three-tiered cookie, marshmallow and cereal bars. —Denise Kirsch, McLeansboro, Illinois
  • Total Time
    Prep: 20 min. Bake: 15 min. + chilling
  • Makes
    2 dozen


  • 1 package (17-1/2 ounces) peanut butter cookie mix
  • 3 tablespoons canola oil
  • 1 tablespoon water
  • 1 large egg
  • 1 package (10 ounces) peanut butter chips
  • 2/3 cup corn syrup
  • 1/4 cup butter, cubed
  • 2 cups Rice Krispies
  • 2 cups salted peanuts
  • 2 teaspoons vanilla extract
  • 3 cups miniature marshmallows


  • In a large bowl, combine the cookie mix, oil, water and egg. Press onto the bottom of a greased 13-in. x 9-in. pan.
  • Bake at 350° for 12-15 minutes or until set. Meanwhile, in a large saucepan, combine the chips, corn syrup and butter. Cook and stir over medium-low heat until smooth. Remove from the heat. Stir in the Rice Krispies, peanuts and vanilla.
  • Sprinkle marshmallows over crust. Bake 1-2 minutes longer or until marshmallows begin to puff. Spread cereal mixture over top. Cool completely on a wire rack. Refrigerate until firm. Cut into bars.

Test Kitchen Tips
  • These freeze very well.
  • Need a dose of chocolate? Dip each bar into melted chocolate (it looks pretty, too!) or add chocolate chips or chunks to the Rice Krispies and peanut mixture before spreading it in the pan.

      Very good IF you like peanuts and very sweet treats. Because of COVID-19 I was only able to find large marshmallows and it's not easy to measure them out. I used the entire bag which is maybe why mine were extra sweet. I didn't mind it, I just could only eat a small portion at a time. I probably won't make it again because only myself and one of my kids enjoyed it but it's still a good recipe and worth a try if it suits your taste.

      Keeper! Very similar to brownie mallow bars on this site-which have chocolate & PB that I have made a million times. Love the peanutty, salty, sweet, crunchy, gooey flavor-like an upscale fluffernutter. Keeps well in the fridge, freezable & easy to take along. Thumbs up from everyone that tried them. If you like a Payday candy bar, this is your recipe. I can't believe I am making this again for Labor Day so many years later (2017), so good, so easy. Also, the tip on leaving it out to warm up a bit before cutting is right on!

      Everyone loved these! They are pretty hard to cut when you first take them out of the refrigerator. I let them sit out for about a half an hour and then cut them into the bars. Excellent recipe!!!!!

      These are delicious - a bit hit at my son-in-law's B-day party.

      Keeper recipe, I'm not a big marshmallow person but, these are truly delicious. I have made them twice now, the last time I added a few chocolate chips to the top after I spread the peanut butter mixture on.

      This recipe is a family favorite. When giving recipes to new brides I always include this one and have given it out many times. If you take it to a party or picnic, plan on coming home with an empty plate.
