Mille Feuille is a dessert made of 3 layers of puff pastry, filled with a rich Crème Patissiere and decorated with a glaze that is feathered. My version of this dessert uses a Crème Diplomat filling which is a little bit lighter. Also in the recipe, I made a Cheats Puff Pastry which saves a lot of time! I decided to stick to the classic design of this dessert but I made a little change which I think makes the Mille Feuille taste a lot better.
