Preheat oven to 350 degrees. Spray bottom only of a 9x13" baking dish with cooking spray, and lightly flour. In a large bowl, using a spoon, combine cake mix, butter, water and eggs until dough forms (some dry mix will remain). Stir in cranberries, baking chips and cashews. Spread evenly in pan. Dough will be stiff. Bake 20 to 25 minutes or until wooden toothpick inserted in center comes out clean. Cool completely and cut into bars.
