1. Prepare pan. Lightly spray x 9×13 pan or line with parchment paper for easy removal. You can use a smaller pan if you want thicker treats.


2. Combine butter and peanut butter. In a large, heavy-bottomed pot, over low heat, melt butter and peanut butter together until completely melted and smooth.


3. Melt marshmallows. Set aside 2 cups of the marshmallows. When butter is melted, add the remaining marshmallows. Stir with a rubber spatula or a wooden spoon until melted.


4. Add vanilla and salt. Remove from heat. Stir in vanilla extract and salt.


5. Add remaining ingredients. Stir in remaining 2 cups mini marshmallows, rice krispies and peanut butter chips.


6. Press in pan. Spread in pan (I like to use a piece of saran wrap lightly sprayed with cooking spray to help make this part easier and press the mixture into the pan this way or you can spray your hand with cooking spray ) and press into the pan. Be sure to not press down too hard or it can make them very hard and compact. Let sit for 1 hour to harden. Cut into squares and enjoy.
