This recipe for s'mores cookies, a popular treat overseas, is easy to make at home using whole wheat biscuits, chopped chocolate, and plenty of marshmallows. The dough is made by mixing unsalted butter, granulated sugar, beaten egg, all-purpose flour, cocoa powder, and baking powder. Crushed biscuits, marshmallows, and chocolate are then added and baked. The cookies are delicious when hot, with the marshmallows melted, and become moist as they cool. They're perfect for enjoying at home or as a gift.
