Ingredients

Scale

Cookie Base

  • 2 cups gluten-free all-purpose flour
  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract

Toppings

  • 1 cup semi-sweet chocolate chips or chunks
  • 1 1/2 cups large marshmallows

Instructions

  1. Prepare the dough: In a mixing bowl, cream together the softened butter and sugar until light and fluffy. Beat in the egg and vanilla extract until fully combined. In a separate bowl, whisk together the gluten-free flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until a cohesive dough forms.
  2. Press the dough into the pan: Grease a 9×13-inch baking pan lightly with butter or non-stick spray. Evenly press the cookie dough into the pan, creating an even layer covering the bottom.
  3. Add the toppings: Sprinkle the chocolate chips evenly over the pressed dough. Then, layer the marshmallows evenly on top of the chocolate to cover the entire surface.
  4. Bake the bars: Preheat the oven to 350°F (175°C). Bake the cookie bars in the preheated oven for 20-25 minutes or until the marshmallows are golden brown and the edges of the cookie base are set and lightly browned.
  5. Cool and serve: Remove the pan from the oven and allow the bars to cool completely before cutting into squares. This helps the chocolate and marshmallow toppings to set for easier slicing and serving.

Notes

  • Use gluten-free all-purpose flour blend with xanthan gum included for best results.
  • For extra richness, substitute half of the butter with browned butter.
  • To get perfectly toasted marshmallows, you can broil the bars for 1-2 minutes after baking, watching carefully to prevent burning.
  • Store leftover bars in an airtight container at room temperature for up to 3 days.
  • These bars can be made ahead and reheated briefly in the microwave to restore gooeyness.
