  • Melt together butter, peanut butter, and butterscotch chips on very low heat until mixed, stirring constantly. Cool for a bit (so as not to melt the marshmallows).
  • Stir in mini marshmallows.
  • Pour in a greased 11" x 13" pan.
  • Refrigerate and cut into small (1-1/2") squares.

    Why do my marshmallows always float to the top so that the bottom is only the pb/marshmallow/butter mixture?

    Can use a graham cracker crumb base / crust.

    I actually add rice krispies to mine! It gives it that exrta crunch and texture. Very yummy

    I had planned on making these all day..lo and behold, I get to the grocery store and they do not sell butterscotch chips!?! I say what the heck and grab the Hershey's milk chocolate chips. Oh my gosh!!! I have no idea what the original recipe tastes like and I doubt I ever will, because these were just unbelievable awesome. I used chunky peanut butter and lined the dish with wax paper..had no problem cutting or getting them out..only problem was not eating them all!! MMMMM

    If you want it to come out of the pan easier, line the pan with wax paper or tin foil. Then pull on the sides and it should just pop out.

    These are a lot easier to cut and get out of the pan if you freeze them first. They thaw well and are still a great gooey treat.

    I’ve made this recipe many times- here are my tips - Melt your butter and peanut butter on the stove, then remove it from heat and stir in your butterscotch chips. This keeps the mixture from getting grainy. -Add more marshmallows than the recipe calls for. I add double, and I use multicolored marshmallows -Grease your pan, then put it in the freezer while you melt your butters so that it has a head start on cooling time That’s all! Good luck!

    I suggest adding shredded coconut and Vanilla. Makes the taste even better!

    I substitute the peanut butter for Nutella and substitute the butterscotch chips for semi sweet chocolate chips. For my Nutella/ chocolate loving daughter.
