Preheat the oven to 350 degree F. Lightly coat a 13x9x2-inch baking pan with cooking spray or grease with shortening. In a large mixing bowl beat together cake mix, milk, and butter until well mixed. Stir chopped nuts into the beaten mixture.
Spread half of the mixture into prepared pan. Bake in the 350 degree F oven for 10 minutes. Sprinkle with chopped candy. Drop remaining cake mixture by teaspoons over all. Bake about 15 minutes more or until a wooden toothpick inserted near center comes out clean. Cool on a wire rack. Cut into rectangles. Makes 36 servings.
