You'll find it nearly impossible to resist this rich chocolate delight. It's chock-full of marshmallows and graham crackers—and no one will believe that the tantalizing treat is low in fat. —Holly Mann, Temple, New Hampshire
2 whole reduced-fat graham crackers, broken into bite-sized pieces
Line an 8-in. square pan with foil and coat with cooking spray; set aside. In a small heavy saucepan over low heat, melt chocolate chips with milk; stir until smooth. Remove from the heat; cool for 2 minutes. Stir in vanilla. Fold in marshmallows and graham crackers.
Pour into prepared pan. Refrigerate for 1 hour or until firm.
Using foil, lift fudge out of pan. Discard foil; cut into 48 pieces.
