1 box devils food cake mix
1 - 4 1/2 oz. box chocolate instant pudding and pie filling
1 - 6 oz. pkg. semi-sweet chocolate chips
2 eggs
1/4 cup vegetable oil
1 1/4 cup water
Pkg. of 6 plain Hershey's candy bars

Combine all ingredients and stir vigorously for 1 minute. Pour into
greased 13 X 9 inch cake pan. Bake in preheated 350 oven for 40-45
minutes or till cake springs back in center when touched.

Then, while it's still hot from the oven, place the Hershey's chocolate candy bars over the entire top of the cake. Let cake sit for a few minutes so the chocolate will melt and then spread the melted chocolate out over the cake.

You need to eat the cake while it's hot (of course, you can always reheat individual pieces in the microwave) and put a scoop of vanilla ice cream and some whipped cream on top of each slice.
