Preheat your oven to 350°F (175°C) and line an 8-inch square baking pan with parchment paper, leaving some overhang for easy removal later.
In a medium bowl, combine the graham cracker crumbs, salt, peanut butter, and honey (or maple syrup). Mix until the mixture is well combined and resembles a thick dough.
Press two-thirds of the graham cracker mixture firmly into the bottom of the prepared baking pan to create a base layer.
Evenly distribute the mini marshmallows and chocolate chips over the pressed mixture, spreading them out for even coverage.
Crumble the remaining graham cracker mixture over the top of the marshmallows and chocolate chips. Press down gently to help adhere everything together.
Optional: Sprinkle the chopped peanuts across the top for an added layer of crunch and flavor.
Bake in the preheated oven for 15-18 minutes until the marshmallows are puffed and golden.
Remove from the oven and let cool in the pan for about 10 minutes, then use the parchment paper to lift the bars out. Allow to cool completely on a wire rack before cutting into squares.
Notes
Serve on a colorful plate, drizzled with melted chocolate and garnished with whole roasted peanuts.
