I remember having mille feuille as a kid and absolutely loving it. This was my first attempt ever at making one and it turned out so well and of course it's egg-free and dairy-free. For me it was important to keep the recipe as easy and accessibly as possible. It's that easy you can get all ingredients in your supermarket as well which is even better. And the home-made custard tasted even better than I could've imagined, better than the store bought one!
