Equipment

  • 1 9 x 9 (23 cm) pan
  • 1 sheet wax, parchment paper or foil
  • 1 large pan

Ingredients
  

  • 6 tablespoons (85 g) unsalted butter, cubed
  • 10 oz. mini marshmallows, divided
  • ½ cup (128 g) creamy peanut butter
  • 1 teaspoon vanilla extract
  • ¼ teaspoon salt
  • 6 cups (159 g) Rice Krispie cereal
  • ½ cup peanut butter chips, optional
  • flaky salt for topping, optional

Instructions
 

  • Grease and line a  9x 9 or 9 x 13 pan with wax paper or foil along the bottom and two sides of the pan.
  • In a sauce pan or pot, melt the butter on low heat until the butter to begins to foam. Once it starts to foam, whisk or stir the liquid butter frequently. The butter will begin to smell nutty and very fragrant. Once the foam has subsided, the butter should have some brown, lightly toasted bits floating at the bottom.
    6 tablespoons (85 g) unsalted butter, cubed
  • As soon as the butter has browned, add most of the marshamllows and peanut butter. Reserve ¾ cup mini marshmallows for stirring into the treats. I suggest adding the peanut butter first and then the marshmallows.
    Stir continuously over low heat until the marshmallows are mostly melted and are well combined with the peanut butter and butter. Once the marshmallows are mostly melted remove the pot from the heat. Stir in the vanilla extract and salt. 
    10 oz. mini marshmallows, divided, ½ cup (128 g) creamy peanut butter, 1 teaspoon vanilla extract , ¼ teaspoon salt
  • Add the rice krispie cereal directly to the pan if possible. If not, make sure all the cereal is in a large bowl and pour the melted marshmallows directly into the bowl of cereal. Quickly and carefully stir the cereal and gooey peanut butter marshmallows together until well combined. Add the reserved ¾ cup mini marshmallows into the cereal treats until just combined. If you are using peanut butter chips as well, stir them into the gooey mixture along with the reserved marshmallows.
    6 cups (159 g) Rice Krispie cereal, ½ cup peanut butter chips, optional
  • Evenly scoop the gooey and nutty cereal treats into the prepared pan. Gently press the peanut butter rice crispy treats into place. Allow the treats to set for at least 30 - 60 minutes, then top with flaky salt if you like, slice and enjoy.
    flaky salt for topping, optional
