Girl Scout cookie season is one of the most delicious times of the year. When buying Girl Scout cookies, you are not only supporting a great organization, but you get to enjoy the iconic treats. One of the most popular Girl Scout cookie offerings is the S'mores cookie—crunchy graham sandwich cookies with creamy chocolate and marshmallow filling.

This recipe for Girl Scout Cookies s'mores bars is twice the s'mores goodness in every bite. The recipe starts with a homemade brownie batter as the base. After the brownies are baked they are topped with graham cracker crumbs and the Girl Scout S'mores cookies are pressed into the warm baked brownies. Next, the brownies are topped with pieces of chocolate bars and sprinkled with mini marshmallows. The marshmallows can be toasted with a kitchen torch (with parental supervision, of course) or baked in the oven a few minutes until golden brown. If you love s'mores, this recipe is twice the fun!

  7. Use a kitchen torch to lightly toast the marshmallows. Alternately, the pan can be returned to the oven and baked until the marshmallows puff and lightly brown, about 3 minutes. Cool until the topping hardens before slicing and serving.

Tip

By lining a pan with non-stick foil, you are creating easy "handles" to pick up the baked and cooled bars and lift them from the pan. The bars can then be transferred to a cutting board for neat, even slicing. If you don't have any non-stick foil, parchment paper also works well. Of course, you can always grease the pan with butter or baking spray and cut the bars directly from the baking pan as well.
