Turn the square of dough so it's shaped like a diamond, with one tip at the top and one at the bottom. Spread 1 tablespoon of the marshmallow fluff in each square, forming a thick line from the top corner of the square to the bottom. Sprinkle with mini chocolate chips and graham cracker crumbs. Fold the side corners in and over. Place on a baking sheet. Repeat with remaining dough.
