How to Make Peanut Butter Marshmallow Squares
Freeze marshmallows: Start by freezing the mini marshmallows for 35-45 minutes. This will help them maintain their shape and texture once mixed.
Prep the pan: Line an 8×8 or 9×9 inch baking pan with parchment paper, leaving some overhang for easy removal later. This will ensure your squares come out easily.
Melt butterscotch chips: In a large pot over low to medium heat, melt butterscotch chips, stirring often. Keep at it until about 75% melted, which should take around 2-3 minutes.
Mix in peanut butter: Add the creamy peanut butter to the pot and stir for another 2 minutes, or until the mixture is smooth and well combined.
Incorporate butter and vanilla: Stir in your unsalted butter and vanilla extract, mixing on low heat until everything is fully melted and glossy.
Cool the mixture: Remove the pot from heat and let it cool for about 5 minutes. This step is important for keeping the marshmallows intact.
Fold in marshmallows: Gently fold the cooled peanut butter mixture with the frozen marshmallows until they’re evenly distributed. Be careful not to crush them!
Pour into the pan: Transfer the mixture into your prepared pan, spreading it evenly with a spatula. Then cover it tightly with plastic wrap.
Chill and serve: Refrigerate for at least 1.5 hours or overnight. Once set, slice into squares, serve, and enjoy the delightful flavors!
Optional: Drizzle with melted chocolate for added indulgence.

Expert Tips for Peanut Butter Marshmallow Squares
• Chill the Marshmallows: Freezing the mini marshmallows is crucial to prevent them from melting into the mixture; this retains their chewy texture.

• Storage Tips: Keep your Peanut Butter Marshmallow Squares in an airtight container for freshness up to 7 days. For longer storage, freeze them in squares for up to 4 months.
• Field Variation Ideas: Experiment with different chips like dark chocolate or caramel to customize your squares; the possibilities are delicious!
