Samantha Erb
My chocolate chip marshmallow cookies are soft, chewy, and filled with marshmallows and chocolate chips. It's like a s'more, but in cookie format!

Ingredients

  • 12 tablespoons unsalted butter melted
  • 1 cup light brown sugar
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 1 ¾ cups all purpose flour
  • 1 teaspoon baking soda
  • ¼ teaspoon kosher salt
  • 1 cup chocolate chips
  • 1 cup marshmallows

Instructions
 

  • Whisk together the melted butter and brown sugar in a large bowl. Then add the egg and vanilla extract and whisk to combine.
  • Add the flour, baking soda, and salt. Mix just until no large lumps of flour remain. 
  • Next, add the chocolate chips and marshmallows. Gently fold them into the cookie dough, making sure not to rip the marshmallows. 
  • Cover the cookie dough and place it in the fridge to chill for 30 minutes (or up to overnight). While the dough is chilling, preheat the oven to 350 degrees F and line two large baking sheets with parchment paper. 
  • When the dough is chilled and solid, scoop out 2-tablespoon-sized portions and place them at least 2” apart on the prepared baking sheet. 
  • Bake the cookies for 12-14 minutes, until they are barely golden brown around the edges.
  • Carefully tap the baking sheet on the counter a few times to sink the cookies and then allow them to cool completely on the tray.

Notes

  • Only mix the butter and dry ingredients until there are no large lumps of flour left.
  • Fold the marshmallows in carefully so they don’t rip.
  • For even cookies, use a cookie scoop to scoop the dough onto the baking sheet.
  • Chilling the dough briefly before the cookies bake keeps the marshmallows from melting too quickly in the oven.
  • Tap the cookie tray on the counter when the cookies come out of the oven to sink the centers for a perfect, chewy texture.
  • Store leftovers in an airtight container on the counter for up to 5 days.
