Not yo’ mama’s

Peanut Butter Fudge Krispies

I don’t know what possessed me to make these evil, evil things. Rice krispy treats laced with peanut butter and studded with salted peanuts? A layer of creamy peanut butter fudge? And a slathering of dark chocolate fudgy frosting to top them off? Am I really that batty! Clearly these are not yo’ mama’s rice krispy treats. My hips are a bit perturbed. My jeans refuse to speak to me. Fortunately a certain someone doesn’t find these too rich and will be forced to help me eat them. As will anyone I happen to run into this week.

I don’t think rice krispy treats need fussing with. The classic recipe from your mama’s mama has always been a winner in my book. But every once in a while good things deserve a little extra lovin’. I mean, do Oreos really need to be coated in chocolate? Or cheesecake deep fried? Or Krispy Kremes turned into bread pudding? I should probably say no. But that would be like me saying rice krispy treats don’t need a layer or two of fudge. And, well…

…rice krispy treats totally deserve a layer or two of fudge once in a while. And don’t just take my word for it. Make these. Soon. They will keep for a couple days at room temperature and for about a week in the fridge (just allow them to come to room temperature before enjoying). And don’t be intimidated by the length of the recipe. It’s just three incredibly simple recipes rolled into one.

A quick shout out to my dear AT, the cutest new mommy I’ve ever seen, and the only person I know who has as crazy an affinity for rice krispy treats (and buttercream and cookie cake and nachos) as I do. And a very Happy Birthday wish to our man, G$! :)

Peanut Butter Rice Krispy Treats

(Adapted from the back of the box)
  • 3 T unsalted butter
  • 1 10-oz bag marshmallows
  • 1/2 cup smooth peanut butter
  • 1/2 tsp vanilla
  • 1 cup roasted salted peanuts
  • 6 cups crispy rice cereal

Line a 13×9 inch pan with parchment or foil. In a large saucepan, melt butter over low heat. Add marshmallows and stir until completely melted. Remove from heat and stir in peanut butter and vanilla. Using a wooden spoon, add peanuts and crispy rice cereal and stir until well coated. Using a buttered spatula or a piece of wax paper, evenly press mixture into prepared pan. Set aside as you prepare the peanut butter fudge.

Peanut Butter Fudge

(Adapted from Alton Brown)
  • 1/2 cup (1 stick) unsalted butter
  • 1/2 cup creamy peanut butter
  • 1/2 tsp vanilla
  • 1/2 lb powdered sugar

Microwave butter and peanut butter for 2 minutes on high. Stir and microwave on high for 2 more minutes. Add vanilla and powdered sugar to peanut butter mixture and stir to combine with a wooden spoon. Spread evenly over rice krispy layer and refrigerate bars while you prepare the frosting.

Dark Chocolate Fudge Frosting

  • 3 cups semi-sweet chocolate chips
  • 1 can sweetened condensed milk
  • 1/2 tsp vanilla

In a medium saucepan, combine chocolate chips and sweetened condensed milk. Heat over medium-low heat until chocolate melts, stirring occasionally. Remove from heat and stir in vanilla. Spread evenly over peanut butter fudge later.

Allow bars to cool until frosting sets, about 30 minutes (or 15 minutes in the fridge if you’re as impatient as I am). Remove from pan and transfer to a cutting board. Cut into 1-inch squares.

Makes about 50 1-inch squares.

    Oh yes please. I’m all for tarting up good old treats when chocolate and peanut butter is involved. These look dangerously good…!

    This is the second peanut butter/chocolate type bar I’ve seen this week, and I have my own to post, too! All are very different though, and your version looks super yummy!! I might just have to try yours, especially with the rice krispies in them :-)

    Oh my lord, these look amazing. My mother-in-law makes a very similar bar and they are so dangerous! I simply can’t resist the combo of crispyness with peanut butter and chocolate. Your pictures make them look even more lovely! Those tooth marks are great! Yum!

    Oh, goodness. This looks amazing. I’m not crazy about Rice Krispie Treats, but with these additional toppings, I think I could tolerate them :)

    These look perfect, really, I like how you can neatly see each layer. I bet these things are so addicting! That is why I have never made them!

    These look terrific!

  18. Pfff… i know you can have everything as long as it is “with moderation”… but how do you want to implement the “with moderation” with such a tempting treat?

    I made these for a party last night and they were a HUGE hit!! Everyone wanted the recipe! I kept some for myself but I will now be bringing them to work tomorrow because I will eat all of them, otherwise – no self control, sad!

    I made these, with a few exceptions. I didn’t have the ingredients for the fudge and frosting, so I just melted chocolate and poured it over the top. Oh, and I accidentally used expired marshmallows so they never fully melted. This was still delicious! Thanks for the awesome recipe. I’ll definitely make these again!
