These peanut butter s’mores bars combine a buttery graham cracker crust with creamy peanut butter, melted chocolate, and toasted marshmallows for a rich and nostalgic dessert. Every bite is soft, gooey, crunchy, and packed with classic s’mores flavor enhanced by peanut butter richness.

Ingredients

2 cups graham cracker crumbs

1/2 cup unsalted butter, melted

1/4 cup granulated sugar

1 cup creamy peanut butter

1/2 cup powdered sugar

1/2 teaspoon vanilla extract

1 1/2 cups milk chocolate chips

1 tablespoon butter

2 to 3 cups mini marshmallows

Instructions

  1. Preheat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper, leaving overhang on the sides for easy removal.
  2. Combine the graham cracker crumbs, melted butter, and granulated sugar in a bowl until the mixture resembles wet sand.
  3. Firmly press the crust mixture into the bottom of the prepared pan in an even layer.
  4. Bake the crust for 8 to 10 minutes until lightly set, then allow it to cool slightly.
  5. Mix the peanut butter, powdered sugar, and vanilla extract together until smooth and thick.
  6. Spread the peanut butter mixture evenly over the cooled crust.
  7. Melt the chocolate chips and butter together in the microwave in short intervals, stirring until smooth.
  8. Pour the melted chocolate over the peanut butter layer and spread evenly.
  9. Sprinkle the mini marshmallows evenly across the chocolate layer.
  10. Return the pan to the oven and bake for 5 to 7 minutes until the marshmallows are puffed and lightly golden.
  11. For darker toasted marshmallows, broil for 1 to 2 minutes while watching carefully to prevent burning.
  12. Allow the bars to cool completely at room temperature, then chill if needed until fully set.
  13. Lift the bars from the pan using the parchment paper and slice into 12 squares before serving.

Notes

Use semi-sweet chocolate chips for a less sweet flavor.

Crunchy peanut butter adds extra texture to the filling.

Add chopped peanut butter cups between the layers for a richer dessert.

Sprinkle crushed graham crackers on top after baking for added crunch.

Chill the bars before slicing for cleaner cuts.

Store in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week.

Freeze for up to 2 months and thaw in the refrigerator before serving.
