1 box yellow cake mix
1 8 oz jar caramel ice cream topping
1 14 oz can sweetened condensed milk
4 to 6 butterfinger candy bars full size, crushed

Prepare and bake cake using directions for 13x9 cake pan. Pierce cake several times with handle of a wooden spoon. Mix caramel topping and condensed milk in a bowl. Pour over cake. Sprinkle with half the candy bar crumbs. Spread whipped topping over cake and sprinkle with remaining crumbs. I drizzle caramel and chocolate syrup over the top. Chill until serving time.
