Peanut Butter S'mores Skillet Cookie

This Peanut Butter S'mores Skillet Cookie is thick peanut butter cookie that is baked in a cast-iron skillet so you get the crispy edges with an extra gooey center. It is topped with melty chocolate and toasted marshmallows. It can be ready in about 30 minutes and is a great skillet dessert to share or an indulgent single serving!

Ingredients

For Cookies:

  • 1 stick (113 grams) unsalted butter room temperature
  • ½ cup (134 grams) creamy peanut butter
  • ½ cup (99 grams) granulated sugar
  • ½ cup (106 grams) brown sugar packed
  • 1 large egg
  • 1 ¼ cup (150 grams) all-purpose flour
  • ½ teaspoon baking soda
  • ¾ teaspoon baking powder
  • ¼ teaspoon salt
  • ½ cup (85 grams) chocolate chips
  • marshmallows as needed

Instructions

For Cookies:

  •  Preheat your oven to 375 degrees (F). Set aside a 6.5-inch cast Iron skillet or a 6.5 Inch baking dish that has been sprayed with non-stick spray.
  • In a medium bowl cream the butter, peanut butter, and both sugars with a hand mixer until creamy and smooth. Add the egg and mix to fully combine.
  • In a separate bowl, combine the flour, baking powder, baking soda, and salt. Whisk to combine.
  • Press the peanut butter cookie dough into the prepare skillet. Place the skillet cookie in the oven with a cookie sheet underneath it to catch any that might spill over.
  • Bake for 20-25 minutes or until the outside of the cookie is golden brown and the center isn't too soft.
  • Remove the cookie from the oven and cover it with the chocolate. If you are using mini marshmallows you cover the top of the cookie with them now. If you are using regular marshmallows, like I did, cut them in half and arrange them on top of the chocolate.
  • Turn your oven to broil and place the cookie back in the oven until the marshmallows are toasted to your liking.

Notes

  • Don't over mix. You need to mix your batter until all of the ingredients are JUST combined, otherwise, you will make too much gluten and your cookie will be tough instead of tender.
