Puff pastry is rolled up two pieces that unfolded and we cut each in half. 4 obtained the base. Pierce each with a fork, not inflate during baking and place in a baking dish. I uploaded pictures of visible detail. Bake in preheated oven at 200-220C degrees. And should make the cream. Beat eggs with a good part of the sugar until fluffy, add 1 cup of milk, pudding bag and finally the flour. The rest of the milk, heat and before starting to boil sent down the thickening mixture and stir until thickening cream. But before this reduction plates, not burn cream. To the hot cream, add vanilla sugar packet and packet butter (cream that my department and I use it for pretty pastries). Stirring, until melted the butter and leave to cool down. At least to me it is easier then in assembling the cake when the cream has cooled down and is tight. It is best to first make the cream and then bake the bases, as I did. It and sticking the cake, all 4 the base, crop than countries hem align, yet and I clippings to crushing and then use to sprinkling on the cake. Between put and ground walnuts, finally finished with cream, chopped walnuts and clippings and paste anywhere nice with them. The result is wonderful - with a sharp knife cut the cake.
