Take apples out of the liquid and place on the baked dough. Use the liquid instead of milk to prepare pudding according to manufacturer's instructions. Pour pudding over apples.
* The original recipe asks for 2 1/2 cups sugar. It was too sweet for me, so I used just 1 1/2 cup sugar.
** I used 2 packets of vanilla pudding that need to be cooked in 4 cups milk (or, in this case, apple juice). If you have different kind of pudding in your country, adjust the quantity accordingly. The pudding I used contained nor sugar neither sweetener.
