S'more Oatmeal Cookies

I got this recipe from a friend a few years ago, who got it from a newspaper. I'm not sure which newspaper. I've made a few different s'mores cookies over the years, and this is one of my favorites. It's a little different from your typical s'mores with the addition of the oats, but they add a good texture to the cookies! I love all kinds of s'mores- campfire s'mores, cupcake s'mores, brownie s'mores...I could go on and on. These cookies are at the top of my list as well : ). The marshmallows sometimes spread out too much on some of the cookies, making it difficult to get them off the cookie sheet. You can keep these broken pieces yourself to enjoy and share the prettier cookies with friends and family : ). This recipe will give you a good arm workout, as you have to stir in by hand the oats, chocolate chips, marshmallows and graham cracker crumbs. You will love these cookies, I promise!

Here's the recipe:
(Source unknown)

1 1/2 Cups all purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 cup butter, room temperature

3/4 Cup packed brown sugar
1/4 Cup granulated sugar
2 eggs
1 teaspoon vanilla extract
3 Cups rolled oats
1 Cup chocolate chips
2 Cups mini-marshmallows
8 coarsely crushed graham crackers (I used 1/4-1/2 cup of graham cracker crumbs)

Heat oven to 350 degrees. Line two baking sheets with parchment paper or spray sheets with cooking spray. In a medium bowl, whisk the flour, baking soda and salt together. Set aside. Use stand mixer on medium speed to beat the butter and both sugars until creamy, about four minutes. With mixer on low, one at a time, add the eggs, beating gently until combined. Add vanilla then add flour mixture. Stir in oats, chocolate chips, marshmallows and graham crackers until combined. Evenly space rounded tablespoons of dough on baking sheet, leaving plenty of room between them. Bake cookies 10 to 12 minutes or until golden brown. Cool for 5 minutes on baking sheets then transfer to wire rack.
