Servings: 8 servings

Ingredients

  • 1 cup unsalted butter softened
  • 1 cup light brown sugar packed
  • 1 cup granulated sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 2 teaspoons cornstarch
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt or to taste
  • 1 1/2 cups mini semi-sweet chocolate chips
  • 1 cup mini marshmallows

Instructions

  • In a mixing bowl, beat together the softened unsalted butter, light brown sugar, and granulated sugar until the mixture is light and fluffy. This should take about 3-5 minutes.
  • Add the large egg and vanilla extract to the butter-sugar mixture. Beat until fully combined and smooth.
  • In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring until just combined.
  • Gently fold in the mini semi-sweet chocolate chips and mini marshmallows until evenly distributed throughout the cookie dough.
  • Grease your 9-inch pie dish lightly with butter or non-stick spray.
  • Pour the cookie dough into the prepared pie dish and spread it out evenly with a spatula.
  • Place the pie dish in the preheated oven and bake for about 25-30 minutes, or until the edges are golden brown and the center is set but still slightly gooey.
  • Allow your Gooey Chocolate Chip and Marshmallow Cookie Pie to cool in the dish for about 10-15 minutes before slicing. Serve warm and enjoy!
