Ingredients

  • 10 ounces small marshmallows See note 1
  • 6 tablespoons butter salted or unsalted
  • 1/2 cup peanut butter I tested with natural, See note 2
  • 3 cups Rice Krispies cereal any puffed rice cereal will work, See note 3

For chocolate topping

Makes: 2 x 2inch rectangle

Instructions

  • Lightly grease an 8x8 baking dish with butter. Set aside.
  • In a medium sauce pan, add the marshmallows, butter and peanut butter.
  • Heat over medium low, stirring constantly until the marshmallows and butter melt and the peanut butter incorporates--about 5 minutes.
  • Add the Rice Krispies and stir gently but quickly. Transfer the mixture to the baking dish and press gently the back of a spatula until even. Let the treats cool and set at least one hour.
  • If adding chocolate, it can be poured on before the treats are cool and allowed to set at room temperature.

Notes

Note 1: Small marshmallows melt more evenly than large, but large ones can be used. I tested with Dandies brand that have no high fructose corn syrup or colors.  
Note 2: I tested with natural peanut butter. Make sure yours is smooth and no-stir because the more coarsely ground peanut butters could cause the marshmallows to seize. 
Note 3: I tested with sprouted puffed rice cereal, though any type you like is fine. 
Note 4: Use chocolate chunks or baking squares only. Chips have ingredients that can cause your chocolate to split. 
Note 5: I use refined coconut oil, but you can use avocado oil or vegetable oil. Using regular coconut oil will add a flavor of coconut to your treats.
