My son's favorite cake is butterfinger.
Lucky for me that both cakes are easy to make.
To make a butterfinger cake you will need:
german chocolate cake mix
eagle brand milk
caramel ice cream topping
butterfinger candy bars
Mix cake mix according to directions on box.
Bake in a 9x12 cake pan. Remove from oven. Cool.
Use the end of a big spoon to poke holes in the cake.
Pour can of eagle brand milk over cake.
Pour jar of caramel ice cream topping over cake. Yum. Very rich.
Top with cool whip and butterfingers. (I used three.)
My son asks for this cake every year.
