What Are Peanut Butter S’mores Bars?

Ingredients
- 2 cups graham cracker crumbs (I recommend Honey Maid for that perfect sweetness)
- 1/2 cup unsalted butter, melted (Make sure it’s at room temperature for easy mixing)
- 1/4 cup granulated sugar
- 1 cup creamy peanut butter (Go for Jif or Skippy for a smooth texture)
- 1/2 cup powdered sugar
- 1/2 teaspoon vanilla extract (For that extra hint of flavor)
- 1 1/2 cups milk chocolate chips (Ghirardelli has a great melt; don’t skimp!)
- 1 tablespoon butter (For mixing with chocolate)
- 2 to 3 cups mini marshmallows (Use a generous amount for that gooey topping, and feel free to mix it with seasonal varieties if available)
Prep Notes: Ensure your butter is melted but not too hot to avoid melting the peanut butter mixture in the next step.
Step-by-Step Instructions
-
Preheat your oven to 350°F (175°C) and line an 8×8 inch baking pan with parchment paper, leaving overhang for easy removal.
-
Combine the graham cracker crumbs, melted butter, and granulated sugar in a bowl and stir until the mixture resembles wet sand.
-
Press the mixture firmly into the bottom of the prepared pan using the back of a spoon or a flat glass to create an even layer.
-
Bake for 8 to 10 minutes until lightly set, then remove from the oven and allow to cool slightly.
-
Mix the peanut butter, powdered sugar, and vanilla extract in a bowl until smooth and thick.
-
Spread the peanut butter mixture evenly over the slightly cooled crust, using gentle pressure to avoid disturbing the base.
-
Combine chocolate chips and 1 tablespoon of butter in a microwave-safe bowl, heating in 20-second intervals, stirring between each, until fully melted and smooth.
-
Pour melted chocolate over the peanut butter layer and spread evenly to cover the surface.
-
Sprinkle mini marshmallows evenly across the chocolate layer, ensuring a full, even topping.
-
Return the pan to the oven and bake for 5 to 7 minutes until marshmallows are puffed and lightly golden.
-
Optional: For a deeper golden color, place under the broiler for 1 to 2 minutes, watching closely to prevent burning.
-
Remove from the oven and let bars cool completely at room temperature, then chill if needed to fully set layers.
-
Lift bars from the pan using the parchment overhang and slice into 12 even squares before serving.
