Ingredients

Graham Cracker Crust

  • 1 ½ cups graham cracker crumbs about 9 whole sheets
  • 2 tbs light brown sugar
  • 5 tbs unsalted butter melted

Blondies

  • ½ cup unsalted butter
  • 1 cup light brown sugar
  • 2 ½ teaspoon vanilla
  • 1 egg
  • 1 cup flour
  • optional pinch of salt

Toppings

  • 5 Hershey bars
  • 25-30 large marshmallows cut in half

Instructions

  • Preheat oven to 350°F. Line an 8x8 (pictured) or 9x9 pan with parchment paper and set aside.
  • Stir graham cracker crumbs, melted butter and brown sugar together until all crumbs are moistened. Press into prepared pan and set aside.
  • In a small saucepan turned to medium heat, place butter and brown by swirling constantly until it turns a light brown color. Be careful not to burn. Scrape up all brown bits from the bottom of the pan and pour butter into a large bowl with brown sugar and mix until smooth. Beat in egg and vanilla until combined. Stir in flour until incorporated.
  • Pour the batter on top of graham cracker crust and smooth it out into an even layer. Bake for 25-28 minutes or until a toothpick comes out with a small amount of batter on the bottom - this is what keeps them fudgy.
  • At this point, prepare toppings. Unwrap chocolate bars and cut marshmallows in half because you will need to work fast in the next step.
  • Once the bars are done, pull them out of the oven and switch the oven to broil. Place candy bars in a single layer on top of the hot blondies. Line marshmallow halves on top of the candy bar. Place pan back in the oven under the broiler to brown the marshmallows. Watch carefully.
  • Once marshmallows are browned, let the bars cool for about 20 minutes before cutting into them. I like to stick mine in the fridge for 30 minutes to let the chocolate set up, then I let them sit out at room temperature.
  • The easiest way to cut these brownies is to spray non-stick spray onto the knife each time you slice through or else the marshmallow will be too sticky and unmanageable.

Notes

Storage instructions: S'mores Blondies will stay fresh and marshmallows will stay soft for up to 3-4 days stored in an airtight container in the refrigerator or at room temperature. If storing in the refrigerator, take them out 1 hour before serving to let them come to room temperature.
