Peanut Butter Rice Krispie Treats

What's peanut buttery, sweet, chewy, crispy, (aren't you so glad I didn't just spell that "krispy"?) easy to make, and makes you want more?  This.  This....Reese's Loaf, as JohnPaul called it the first time I made it.  Because Rice Krispie Treats weren't delicious enough, we needed to add peanut butter and Reese's.  Oh yes. 

Peanut Butter Rice Krispie Treats

Makes about 16 squares, but hey, that all depends on who's slicing, doesn't it?


  • 1/4 cup butter
  • 10 oz bag marshmallows, regular or mini
  • 1/2 cup peanut butter
  • 5 cups Rice Krispie cereal
  • 1 1/4 cup mini marshmallows
  • 1 8 oz bag mini Reese's, miniatures, or regular, chopped


Prepare an 8 or 9 inch square baking dish by greasing or lining with parchment paper.

In a large pot over medium-low heat, melt butter and marshmallows.  Stir until combined and smooth. 

Working quickly, remove from heat and stir in peanut butter.  Stir in Rice Krispies.  Gently fold in mini marshmallows. 

Using a well greased hand, scrape Krispies out of the pan and into the baking dish, gently pressing into an even layer. 

Top with mini Reese's and (try to) allow to set before slicing. 

Jenny's Notes:

Optional: For a more loafy loaf of Peanut Butter Rice Krispie Treats, melt a bag (about 10 oz) of peanut butter chips and spread on top of the Rice Krispies, right before adding the Mini Reese's on top.
