Heath Bar Cake

This recipe has been in the family for decades, but I haven't made it for a very long time. When I made it for Bekah's birthday I had lots of requests for the recipe so I thought I'd post it here. It's delicious and pretty easy to make!

1 yellow cake mix
2 c. warm water
2 eggs
1 3oz. package of chocolate pudding

Topping
1/4 c. melted butter
1 c. powdered sugar
