Peanut Butter S'mores Skillet Cookie

Course Dessert

Ingredients

  • 1 cup (2 sticks) unsalted butter, room temperature
  • 1 cup granulated sugar
  • 3/4 cup light brown sugar, packed
  • 2 eggs
  • 1 tablespoon pure vanilla extract
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 3-1/2 cups all purpose flour
  • 2 cups semi-sweet chocolate chips
  • 1 cup creamy peanut butter
  • 1/2 cup graham cracker crumbs
  • 5 (1.55oz. size) Hershey Milk Chocolate Bars
  • 1-1/2 cups mini marshmallows

Instructions

  1. Preheat oven to 350 degrees F.

  2. If your cast iron skillet is well seasoned you probably don’t need to grease it. If it’s not well seasoned or you want to be sure the cookie comes out easily, lightly grease your skillet. (I use a 10" skillet).

  3. In a stand mixer, beat the butter and sugars until light and fluffy.

  4. Add eggs and vanilla, continue to beat until combined.

  5. Add in the salt and baking soda, beating until mixed in.

  6. Gradually add in the flour, then the chocolate chips.

  7. Divide the cookie dough in half. Press half of the cookie dough into the bottom of the skillet.

  8. Top with peanut butter (use an off-set spatula for easier spreading), graham cracker crumbs, chocolate bars (I broke mine into pieces and then placed them on) and marshmallows.

  9. Place remaining dough on top – I did this in pieces, flattening out small pieces in my hand and setting them on. The pieces can touch, but don’t have to, the dough will spread as it bakes.

  10. Bake for 25 minutes or until the top is golden.

  11. Serve while still warm for the ultimate gooey treat!
