How to Make Peanut Butter Marshmallow Squares
-
Prep the Pan: Line an 8×8 baking pan with two sheets of parchment paper, creating a cross for easy removal later. This simple step makes it a breeze to lift the bars out once set!
-
Melt the Mixture: In a large saucepan over medium heat, combine the butter, creamy peanut butter, and butterscotch chips. Stir frequently until everything is melted and smooth. Alternatively, mix in a microwave-safe bowl, heating in 30-second bursts, then reducing to 15 seconds.
-
Cool Briefly: Allow the melted mixture to cool for about 5 minutes. This helps prevent the marshmallows from melting too much, keeping that fluffy texture intact.
-
Fold in Marshmallows: Using a rubber spatula, gently fold in the miniature marshmallows, ensuring they’re evenly coated. Pour the delicious mixture into your lined pan, spreading it out evenly.
-
Chill and Set: Place the pan in the refrigerator and chill for at least 1 hour, or until the bars are firm enough to cut into squares. Enjoy the anticipation of that first bite!
Optional: Top with chopped nuts for an extra crunch!

Tips for the Best Peanut Butter Marshmallow Squares
-
Butter Temperature: Use softened butter: Let your butter sit at room temperature to achieve a creamy mixture. Cold butter can create clumps, making blending difficult.
-
Even Melting: Stir frequently: When melting the mixture, constant stirring will prevent burning and ensure everything blends seamlessly together for your peanut butter marshmallow squares.
-
Avoid Marshmallow Meltdown: Don’t overheat: Be cautious not to overheat the mixture before adding marshmallows to keep them fluffy and chewy—this is what makes your squares delightful!
-
Proper Cooling: Cool slightly before marshmallows: Allow your mixture to cool for five minutes before folding in the marshmallows, ensuring they stay intact and give that delicious texture.
-
Setting Time: Allow enough chilling: To get perfectly set squares, chill for at least an hour. Patience pays off when enjoying your homemade treat!
