Ingredients

The following ingredients have 2 Servings
  • 2 tablespoons (28g) butter (melted and slightly cooled)
  • 2 tablespoons (25g) brown sugar
  • 1 heaping tablespoon (18g) granulated sugar
  • 1/4 teaspoon vanilla extract
  • 1 large egg yolk (OR 1 tablespoon whisked whole egg)
  • 1/3 cup (40g) all-purpose flour (measured by weight or using the spoon and sweep method*)
  • 1/8 teaspoon baking soda
  • 1/8 teaspoon salt (if using salted butter, cut salt by half)
  • 1/4 cup (1.5oz) semi-sweet chocolate chips
  • 1/2 graham cracker
  • 3 pieces/segments of a Hershey's bar (or chocolate of choice)
  • 9 mini marshmallows or 1 full-size marshmallow cut in half lengthwise

Instruction

  • Preheat your oven to 350°F and line a baking sheet with parchment paper or a silicone baking mat.
  • In a small bowl, whisk together melted and slightly cooled butter, brown sugar, and granulated sugar. Add vanilla extract and egg yolk, and mix well.
  • Add flour, baking soda, and salt, and use a spoon to stir until combined.
  • Stir in chocolate chips.
  • Scoop out slightly less than half the dough and shape into a disk about 2 1/2 inches across (about the width of a graham cracker). Place disk on prepared baking sheet.
  • Set graham cracker half on top of the dough, followed by chocolate pieces and then marshmallows.
  • Shape remaining dough into a disk and press it over the top of the marshmallows. Smoosh the dough down so the chocolate and graham crackers are completely covered.
  • Bake for 11 to 14 minutes, until the top of the cookie looks mostly set and edges are just starting to brown. Allow to cool on the baking sheet for 5 minutes and enjoy!
