Chocolate Éclair Cake

I don't like chocolate very much but I do love this cake. It's from my friend Nicole. Really good.

1 cup flour
1 cup water
1 stick butter
4 eggs
1 large package instant vanilla pudding
3 c. milk
8 oz. Cream cheese
1 container cool whip
Chocolate sauce:
2 squares unsweetened baking chocolate
1 c. evaporated milk
2/3 c. sugar
Boil 1 cup water, then add butter, stir until melted.
Add flour. Stir in 1 egg at a time. Pour mixture into 9x13 pan and bake for 30 minutes at 400. Mix pudding, milk, and softened cream cheese. After bottom layer has cooled add pudding mixture. Chill for 1 hour. Add cool whip and chill until ready to serve. Make chocolate sauce and pour over cool whip just before serving.
