Preheat oven to 375 degrees.

In a medium bowl, combine flour, graham cracker crumbs, baking soda, and salt. Whisk together. In a large bowl, cream butter, sugar, brown sugar, and vanilla. Add the eggs one at a time, mixing well after each one. Slowly mix in the flour mixture, beating until smooth. Stir in chocolate chips. Drop by rounded spoonfuls onto ungreased cookie sheet.

Bake for 8 minutes and remove from oven. Push 3 or 4 marshmallows and a couple of pieces of chocolate into each cookie. Return to oven and bake an additional 3-4 minutes until cookie is cooked and marshmallows are beginning to brown. Cool cookies on wire rack.
