Ingredients

11 ounce package of butterscotch morsels (I used Toll House)
1 cup creamy peanut butter your favorite brand - I used Reese’s creamy peanut butter
⅓ cup salted sweet cream butter cubed
2 tablespoons heavy cream
1¼ teaspoons pure vanilla extract
5½ cups (1 10-ounce) bag mini marshmallows

Instructions

Line a 9x9 baking dish with parchment paper, leaving an overhang for lifting the bars out of the baking dish. Lightly spray with nonstick cooking spray. Set it aside.
Add the butterscotch morsels, peanut butter, butter, and heavy cream to a 3 to 4-quart heavy-bottomed saucepan over medium heat. Stir constantly until the butterscotch morsels and peanut butter are melted and smooth. Remove from the heat and stir in the vanilla. Allow the butterscotch mixture to cool for 8-10 minutes. Stir occasionally as the mixture cools.
Stir in the miniature marshmallows.
Evenly spread the butterscotch mixture into the prepared baking dish. Chill in the fridge for 45 minutes to 1 hour until set.
Use the parchment paper overhand to lift the bars out of the pan. Slice into 16 slices. Keep refrigerated until ready to serve.

Notes

Storage:

To Store: Store any leftovers in an airtight container in the refrigerator for up to 14 days.
To Freeze: You can freeze the uncut bars for up to 3 months.

Tips:

You can substitute crunchy peanut butter for the creamy peanut butter.
Score the top of the bars with a sharp knife before chilling to make cutting easier.
If you want a colorful alternative, you can substitute the plain mini marshmallows with multi-colored mini marshmallows.
Make sure the mixture has time to cool for a few minutes before mixing in the marshmallows so you don’t melt them.
