S'mores Poke Brownies

Preheat oven to 350º and line an 8"-x-8” pan with parchment.  Line bottom of prepared pan with graham crackers, if using (you may need to trim some). Prepare brownie mix according to package directions and pour into prepared pan. Bake until a toothpick inserted into center of brownies comes out with a few moist crumbs, about 45 minutes. Let cool, 20 minutes.  Heat broiler. Using the bottom of a wooden spoon, poke holes all over brownies. Microwave marshmallow fluff with 1 tablespoon water until pourable, 20 seconds. Pour into poke holes. Top with a layer of mini marshmallows and broil until golden, 2 minutes. Drizzle with hot fudge and garnish with crushed graham crackers.
