8.65 ounce fun sized Butterfinger candy bars, chopped
Instructions
Prepare cake in a 9x13" pan according to directions on the box. Place pan on a wire rack and cool cake completely.
Poke holes about an inch apart all over cake with the handle of a wooden spoon.
In a small bowl, whisk together the sweetened condensed milk, caramel sauce, and peanut butter. Pour sauce over the cake, trying to fill as many holes as possible.
Whip the cream with a hand mixer till soft peaks form. Add powdered sugar, and vanilla extract and beat till smooth. Spread evenly over the cake.
Cover cake with plastic wrap and chill for at least an hour.
Sprinkle crushed Butterfingers on top of the cake just before serving.
