Step 1

Line a 9 x 9 pan with parchment paper or grease with cooking spray and 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 and Oreo crumble, folding to fully coat the cereal and the Oreos evenly.

Step 4

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

Step 5

Spoon the mixture into the prepared pan, using a rubber spatula coated in cooking spray to press the mixture down into an even layer. Allow to cool for at least an hour before slicing into twelve Rice Krispie treats. Enjoy!
