Recipe Information
Ingredients
- 0.5 cups butter
- 1 cups peanut butter (smooth)
- 1.5 cups butterscotch chips
- 4 cups mini marshmallows
- 1 teaspoons vanilla extract
Instructions
Line an 8x8-inch baking dish with parchment paper, leaving some overhang for easy removal. Set aside.
In a medium saucepan, melt the butter over low heat.
Add the peanut butter and butterscotch chips to the saucepan, stirring constantly until fully melted and smooth. Be sure not to overheat the mixture to avoid it seizing.
Remove the saucepan from the heat and stir in the vanilla extract.
Allow the mixture to cool for about 5–7 minutes, until it is warm but no longer hot to the touch. This prevents the marshmallows from melting completely.
Gently fold in the mini marshmallows until they are evenly coated with the peanut butter mixture.
Pour the mixture into the prepared baking dish, spreading it out evenly and pressing gently with a spatula.
Refrigerate for at least 2 hours or until fully set.
Once set, use the parchment paper overhang to lift the block out of the pan. Slice into 16 squares using a sharp knife.
Serve chilled or at room temperature. Store leftovers in an airtight container in the refrigerator for up to 1 week.
