Instructions

Prepare the pan

Line a 9x9 inch (23x23 cm) baking dish with parchment paper, leaving overhang on the sides for easy removal.

Pro tip: Use metal clips to hold the parchment paper in place.

Melt the base ingredients

In a large saucepan, melt the peanut butter, butter, and butterscotch chips over low heat, stirring constantly until smooth and well combined.

Pro tip: Ensure the heat is low to prevent the mixture from burning.

Cool the mixture

Remove the saucepan from heat and let the mixture cool for about 5 minutes.

Pro tip: Cooling slightly prevents the marshmallows from melting.

Add marshmallows

Fold the miniature marshmallows into the cooled peanut butter mixture until evenly distributed.

Pro tip: Gently fold to keep the marshmallows intact.

Transfer to pan

Pour the mixture into the prepared baking dish, spreading it evenly with a spatula.

Pro tip: Press down gently to compact the mixture.

Chill the squares

Refrigerate the dish for at least 2 hours or until firm.

Pro tip: For a firmer texture, chill overnight.

Tips & Tricks

Use a heavy-bottomed saucepan to prevent scorching.
Chill the squares for at least two hours for easier cutting.
For a nutty crunch, add chopped peanuts to the mixture.

Serving Suggestions

Serve these peanut butter marshmallow squares chilled straight from the fridge for the best texture. They pair wonderfully with a cup of coffee or a cold glass of milk. These squares can be made ahead of time and stored in an airtight container in the fridge for up to a week. If you need to prepare them in advance, they're also freezer-friendly for up to a month—simply thaw at room temperature before serving.
