French Vanilla Slices are called 'Mille-feuilles' and are made with puff pastry sandwiched together with jam, cream or custard. They can be dusted with icing sugar or iced. Make sure you allow time for the pastry to cool before assembling.
I have made similar to this recipe for years now, but I precut the pastry before baking to a uniform size.This prevents breakage of pastry and the under-side is flatter which makes stacking easier.I also use less flour in the custard.Hope this helps others with assembling and presentation. - 12 Jan 2009 (Review from Allrecipes US | Canada)
I saw another mille feuille online which calls for lesser plain flour, I reduced the plain flour to 4 tbsp. I used only 2 sheets of frozen pastry and it took only 10-12mins to bake. My advise is to cut it into serving size before dusting the sugar. Overall, it was presentable and taste yummy and worth a try. - 06 Oct 2005 (Review from Allrecipes US | Canada)
This is one of my favorite deserts. I am from Canada, and a lot of my relatives make these when we go there. Good job! - 24 Mar 2005 (Review from Allrecipes US | Canada)
