Ingredients

Scale

Brown Sugar Butter Paste

  • ½ cup unsalted butter, cut into pieces
  • 2/3 cup packed light brown sugar
  • ½ cup 2% milk
  • 1 teaspoon vanilla extract
  • 1¼ cups graham cracker crumbs

Layers

  • 350 g whole graham crackers (about 32-48, depending on the brand)
  • 2½ cups milk or semisweet (or mixed) chocolate chips or chunks
  • 6 cups mini marshmallows

Instructions

  1. Prepare the Pan: Preheat the oven to 350°F (175°C). Line an 8 or 9-inch square baking pan with parchment paper, allowing the paper to extend above the pan sides by about an inch to make lifting easier.
  2. Make the Brown Sugar Butter Paste: In a medium saucepan over medium-low heat, melt the butter. Whisk in the light brown sugar, 2% milk, and vanilla extract. Heat for about one minute until warmed through to remove chill from the milk, then remove from heat. Whisk in the graham cracker crumbs until you get a smooth, fluid paste.
  3. First Layer Assembly: Arrange a single layer of whole graham crackers evenly across the bottom of the prepared pan. Spoon one third of the brown sugar butter paste over the crackers, spreading slightly but not needing to cover completely. Sprinkle one third of the mini marshmallows evenly on top, followed by one third of the chocolate chips.
  4. Second Layer Assembly: Place a second layer of graham crackers over the marshmallow and chocolate layer. Repeat spreading one third of the brown sugar butter paste, then topping with one third of the marshmallows and one third of the chocolate chips.
  5. Final Layer Assembly: Add the last layer of graham crackers and spread the remaining brown sugar butter paste on top. Finish by sprinkling the remaining marshmallows and chocolate chips evenly over the surface.
  6. Bake the S’Mores: Place the assembled pan in the preheated oven and bake for 16 to 20 minutes, or until the marshmallows on top are golden brown and toasted.
  7. Cool and Serve: Allow the pan to cool on a wire rack. If serving later, chill completely in the refrigerator to make slicing easier. Cut into squares and serve. Store at room temperature for up to 3 days.

Notes

  • For a richer flavor, use semisweet chocolate chips or a mix of milk and semisweet.
  • Chilling the dessert before slicing helps achieve clean squares.
  • This recipe can be doubled in a larger pan if desired.
  • Mini marshmallows provide the best melting texture; regular size may affect layering.
  • Leftovers can be stored in an airtight container at room temperature for up to 3 days.
