Preheat oven to 425 degrees F
In a saucepan, melt the butter with the water at medium heat. When ready, quickly mix in all of the flour until dough forms. let cool most of the way.
When ready mix in the eggs until well combined. The dough should look smooth and shiny. Line a 13x9 pan with parchment paper or spray with baking spray. Spread the dough evenly into the lined baking dish.
Bake in preheated oven for 15 minutes. Reduce the oven temperature to 350 degrees and bake for another 15 minutes. The dough will, puff and then fall. That is normal.
Once cool, spread the chilled pudding in an even layer across the baked dough.
Whip the heavy cream and sugar until you have stiff peaks. Spread over the pudding. Squeeze on top a few lines of the chocolate syrup over the whipped topping. With a toothpick create the design as you see in the video. Keep chilled until ready to serve.
