I can't think of a more fun and delicious mash-up then S'mores Cookies! The chocolate, marshmallow and graham cracker flavor combination you love, transformed into a delicious, chewy cookie.
Preheat oven to 375 degrees F. Line a baking sheet with parchment paper.
In large mixing bowl cream together the butter, granulated sugar and brown sugar for 2-3 minutes. Add egg, egg yolk and vanilla and mix.
Add flour, graham cracker crumbs, baking soda and salt and mix until combined. Stir in chocolate chips.
Refrigerate dough for 15 minutes.
Scoop dough into 2 Tablespoon size balls and place on prepared baking sheet, a few inches apart. Press down slightly on the cookie dough balls, to flatten a little.
Bake for 8 minutes. Remove from oven and gently press 2-3 small pieces of Hershey's chocolate and 2-3 mini marshmallows on the top of each cookie. Return to oven for 3-5 minutes.
Allow to cool on the baking sheet for 5 minutes before moving to a wire rack to cool completely.
