Rainbow S’moreo Cookies

Homemade Oreo-style cookies are pretty great on their own, but they're even better when you add graham cracker crumbs to the cookie dough, stuff them with marshmallow creme, and then roll them in sprinkles. You can change the color of the sprinkles depending on the holiday or occasion you're baking them for. —Colleen Delawder, Herndon, Virginia

    These cookies are pretty messy. The marshmallow fluff does not hold up and will ooze out of the cookies. They are pretty sweet and the chocolate cookies are good, even on their own!

    I made these cookies on 8/19/17! I had at least 30 total cookies and when I paired them together, the sandwiches made about 15! Even by themselves and without pairing the cookies together, these treats are GREAT! I did roll the dough into balls and tried to make them uniform! These cookies are beautiful to look at as well as scrumptious to eat! delowenstein, Volunteer Field Editor

    If you want a VERY sweet treat, this is the recipe for you! I have never made cookie dough with graham cracker crumbs but it worked really well and the dough came together quickly. The cookies are delicious and would be satisfying on their own but if you have a sweet tooth, the marshmallow and sprinkles will send it over the top. If you're not a fan of marshmallow creme, I think pairing the cookies with peanut butter would be perfect for a sweet/salty snack.I might have made these slightly too large - I used a spoon rather than a 1" scoop so I had to guess on size - and will definitely make them smaller next time as I think smaller cookie sandwiches would be a better serving size. A couple of tips: 1.) When you're flattening the dough, flatter = a crisper cookie. 2.) In the flattening process, aim to press each dough ball evenly so your baked cookies will be more uniform in size which helps when you're filling them and rolling the sides in sprinkles (the closer in size the two cookies in the sandwich are, the easier time you'll have rolling them and the better they'll look).
