Step 1

Line a 9 x 9 pan with parchment paper and spray with cooking spray. Set aside.

Step 2

Place butter in a large pot over medium heat. Melt the butter, stirring constantly. Once the butter is melted add the marshmallows and salt. Use a rubber spatula to stir the marshmallows until fully melted, making sure that none of the marshmallows burn. Remove from the heat immediately

Step 3

Add the Rice Krispies, folding to fully coat the cereal.

Step 4

Put the peanut butter in the microwave for 15 seconds or until melted slightly.

Step 5

Drop the melted peanut butter and fluff into the batter and fold a few times to distribute the peanut butter without fully mixing in the peanut butter and fluff. You want there to be thick swirls.

Step 6

Spoon the mixture into the prepared pan, using a rubber spatula coated in cooking spray to press the mixture down into an even layer.

Step 7

Allow to cool for at least an hour before slicing into twelve Rice Krispie treats. Enjoy!
