1Preheat oven to 400. Lightly grease a 9"X13" glass baking pan.
2For the Eclair Crust: In a medium saucepan, melt butter in water and bring to a boil. Remove from heat. Stir in flour. Mix in one egg at a time, mixing completely before adding another egg. Spread mixture into pan, covering the bottom and sides evenly. Mixture will be very wet.
*If the sides of your pan are too greased you won't be able to get the mixture to stay up the sides so make sure to just lightly grease.
3Bake for 30-40 minutes or until golden brown (Mine only took 25 minutes.) You may want to check it occasionally-you don't want to overcook the crust, it will ruin the cake! Remove from oven and let cool (don't touch or push bubbles down).
4For the Filling: Whip cream cheese in a medium bowl. In separate bowl make vanilla pudding by beating the pudding mix and the milk for 3 minutes and put in the fridge until set. Make sure pudding is thick before mixing in with cream cheese. Slowly add pudding to cream cheese, mixing until there are no lumps. Let cool in fridge.When the crust is completely cooled, pour filling in. Top with layer of cool whip however thick you want it and serve with a drizzle chocolate syrup. *If you want to make this even better use homemade whipped cream.
