Ingredients:
- ½ cup (1 stick) unsalted butter
- 1 cup creamy peanut butter (Peter Pan brand recommended)
- 11 ounce bag butterscotch chips (Nestle Toll House brand recommended)
- 1 teaspoon vanilla extract
- 10 ounce bag fruity-flavored mini marshmallows (Jet-Puffed brand recommended)
Preparation:
Step 1: Prepare the Pan
Line an 8×8 inch straight-sided baking pan with parchment paper, ensuring enough overhang on the sides. Lightly spray the parchment paper with non-stick baker’s spray. This makes it easy to remove the chilled squares.
Step 2: Melt the Base
In a 3 ½ – 4 quart saucepan, combine the unsalted butter, creamy peanut butter, and butterscotch chips over medium-low heat. Stir continuously until everything is completely melted and the mixture is smooth.
Step 3: Add Vanilla
Remove the saucepan from the heat. Stir in the vanilla extract. Allow the mixture to cool for 2-3 minutes to prevent the marshmallows from melting when mixed in.
Step 4: Combine with Marshmallows
Pour the mini marshmallows into a large mixing bowl. Pour the slightly cooled peanut butter mixture over the marshmallows. Gently fold to combine until the marshmallows are evenly coated with the peanut butter mixture. Be gentle to prevent the marshmallows from breaking down.
Step 5: Chill and Set
Transfer the mixture to the prepared baking pan. Spread the mixture evenly into a uniform layer. Chill in the refrigerator for 1 ½ – 2 hours, or until the squares are completely firm.
Step 6: Slice and Serve
Once firm, gently lift the peanut butter marshmallow squares from the pan using the overhanging parchment paper. Place the slab onto a large cutting board. Use a large, sharp knife to slice the squares into 16 equal pieces. For cleaner cuts, run the knife under hot water and wipe it clean between each slice.
