  • 1/2 cup granulated sugar
  • 1 cup sourdough starter May vary in consistency.
  • 1 large egg
  • 2 teaspoons vanilla extract

Dry Ingredients

  • 2 1/2 cups all-purpose flour Can substitute gluten-free blend.
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt

  • 1 cup chocolate chips Use chopped chocolate for a cheaper option.
  • 1 cup mini marshmallows Find in the baking aisle.
  • 1/2 cup crushed graham crackers Can substitute digestives.

Instructions
 

Preparation

  • Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
  • In a large bowl, cream the browned butter, brown sugar, and granulated sugar until smooth.
  • Mix in the sourdough starter, egg, and vanilla until well combined.

Mixing

  • In another bowl, whisk together the flour, baking soda, and salt.
  • Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Baking

  • Fold in the chocolate chips, mini marshmallows, and crushed graham crackers.
  • Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them apart.
  • Bake for 12-15 minutes or until the edges are golden while the centers are still soft.
  • Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

For best results, cool browned butter slightly before use. Store cookies in an airtight container with a slice of bread to maintain softness.
