- Nonstick cooking spray
- 2 1/4 cups coarsely chopped roasted salted peanuts
- 50 store-bought soft caramel squares, unwrapped (14 ounces)
- 1 cup mini marshmallows
- Lightly coat an 8-inch square baking dish with cooking spray. Line with parchment paper, leaving a 1-inch overhang on all sides, then lightly coat parchment with spray. Cover paper with 1 1/4 cups peanuts.
- In a medium pot, combine 1 tablespoon water, caramels, and marshmallows over medium. Cook, stirring frequently, until caramels and marshmallows melt and mixture is smooth, about 8 minutes. Immediately pour over peanuts, then top with remaining 1 cup peanuts. Let cool until set, about 2 hours, then cut into 16 bars.
Store in an airtight container with parchment in between layers, up to 2 days.
