I found this on another site and gave it a try, it is like one big eclair in a pan. Easy to make and very good. I used chocolate chips for my Ganache and it worked fine. Ready to serve in about 2 1/2 hours, but better if you make it early in the day. Enjoy!
Preheat an oven to 400 degrees F (200 degrees C). Grease a 9x13-inch baking dish. Place a mixing bowl in the freezer to chill.
Combine the water, butter, and salt in a medium saucepan and bring to a boil over medium-high heat. Reduce the heat to medium and stir in the flour. Cook and stir until the mixture pulls away from the sides of the pan and forms a ball. Transfer the mixture to a mixing bowl and beat in the eggs, one at a time, until fully incorporated. Spread the dough evenly in the bottom of the baking dish.
Bake the pastry in the preheated oven until golden brown, 25 to 30 minutes. (the dough will rise while cooking but will drop some when cooling.) Cool completely on wire rack.
Remove the chilled mixing bowl from the freezer and pour in 2 cups of cold whipping cream. Whip until the cream thickens, about 1 minute; stir in the confectioners' sugar and the vanilla extract. Continue to whip until the cream forms stiff peaks. Refrigerate the whipped cream while you mix the pudding.
Pour the pudding mixes and the milk into a mixing bowl and stir until creamy. Fold in the whipped cream. Spread the filling over the cooled crust and refrigerate.
place the chopped chocolate or chocolate chips in a heat-proof bowl. Bring 1 cup of cream almost to a boil in a small saucepan over medium heat. Pour the hot cream over the chocolate and allow it to soften for 1 minute. Whisk the mixture until smooth. Let the mixture cool slightly to thicken, about 10 minutes. Pour the ganache over the cream filling, spreading to cover the entire surface. Return the pan to the refrigerator and chill for at least 1 hour before serving.
