Using kitchen shears, cut each dinner roll into 4 pieces. Set aside. Spray a 12 cup muffin pan with non stick baking spray. Set aside. In a small bowl melt the butter. Set aside. In separate small bowl add the sugar and graham cracker crumbs together.
Add 5 roll pieces into the melted butter, and then roll them into the graham cracker crumbs. Place 3 dough pieces into each muffin cup and sprinkle some mini chocolate chips and add 5 mini marshmallows over the dough pieces. Add the remaining 2 dough pieces on top of the chocolate chips and marshmallows. You can add a few more chocolate chips on top before baking if you like.
Bake muffins at 375 degrees for 10-14 minutes, or until the rolls are golden brown. Cool muffins in the baking pan 10 minutes before removing to a serving plate. Prepare the glaze and drizzle over each monkey bread muffin before serving.
