Napoleon Cake (Napoleon Tort) is an absolute classic! Popular across the Eastern and Central Europe, this cake is a French-Russian fusion that is simply divine! Made with flaky pastry made with butter and creme fraiche, and layered with rich and creamy creme mousseline, my version of Napoleon Cake also features a couple of layers of tart blackcurrant jam to cut through the sweetness! Not at all difficult to make, and oh-so-good!
