Ingredients Method Notes

Ingredients
  

For the crust
  • 1 cup graham cracker crumbs
  • 1/2 cup unsalted butter, melted
For the filling
  • 1 cup chocolate chips
  • 1 cup mini marshmallows
  • 1 cup all-purpose flour
  • 1/2 cup brown sugar Light or dark brown sugar can be used
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 large egg Best if at room temperature
  • 1 teaspoon vanilla extract

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Grease a 9x9-inch baking pan or line it with parchment paper.
  2. In a large bowl, combine the graham cracker crumbs and melted butter. Mix until combined and crumbly, then press into the bottom of the prepared baking pan.
  3. In another bowl, mix the flour, brown sugar, baking soda, and salt. Add the egg and vanilla extract, blending until a smooth dough forms.
Assembly
  1. Spread the cookie dough evenly over the graham cracker crust. Sprinkle chocolate chips and mini marshmallows generously on top.
Baking
  1. Bake for 25-30 minutes or until the edges are golden brown and the marshmallows are puffed.
  2. Allow to cool in the pan for about 10 minutes before slicing into squares.
  3. Enjoy warm for gooey goodness!

Notes

For a crunchier base, consider adding crushed nuts. Store in an airtight container for up to 4-5 days, or freeze for 2-3 months. Reheat in the microwave for 20 seconds to restore gooey texture.
