Instructions
Spray or lightly butter a 9x9-inch baking pan, then line with a sheet of parchment paper that covers the bottom and two sides, over-hanging the sides slightly to use as handles to remove later. Set aside.
Place marshmallows in large bowl and set aside.
In medium saucepan on the stove top over medium heat, melt the butterscotch chips, peanut butter and butter, stirring regularly until smooth. Remove from heat and allow to cool, stirring occasionally, until you can place your hand comfortably on the bottom of the pan (10-15 minutes)
Pour the cooled peanut butter mixture over the marshmallows. Use a large spoon to gently fold marshmallows into peanut butter mixture, until fully coated.
Spread marshmallows into prepared pan and give pan a jiggle to help settle the marshmallows in the pan. Refrigerate for at least 60 minutes, until mixture has fully set. (I place into the refrigerator uncovered, but will cover with foil once they have cooled for 15 minutes, especially if not cutting right away.)
Run a knife along the 2 uncovered edges of pan, then carefully lift from pan by grabbing the parchment. Place onto a cutting board. Using a large knife, cut into 16 even squares. Make sure to use large knife that allows you to slice straight down, rather than slicing across the bars.
These squares will keep in airtight container in refrigerator for at least 2 weeks, or in freezer for up to 3 months.
Notes
Note 1: In Canada, butterscotch chips are most widely available in 270g packages these days, which is about 50g short of the 2 cups needed here, so you will need 2 packages to get the 2 cups. Bulk Barn has butterscotch chips as well. In a pinch, you can get away with using just one package, though the balance of flavours will be a bit off. I believe the popular US brand is still 11oz, so you should be fine with one package.Note 2: I prefer smooth peanut butter, but you can use crunchy peanut butter if you like. I have not tested these squares with natural peanut butter.Note 3: You can use either salted or unsalted butter. With salted butter, these are a perfect sweet/salty treat. For a sweeter treat, use unsalted butter.An 8x8-inch or 7x11-inch pan will work here, but the squares will be thicker.
