Unfortunately, I later came to their senses. When the cake was in the oven, remember that can be photographed. So I only captured the end result. But it's not terrible. Describe the detailed process. Take a glass of milk (or half a Cup of water mineral with gas and half a Cup of milk), slightly heated, pour the yeast and wait until they dissolve. There also put half the norm of sifted flour. This is our sourdough. After an hour the dough will rise. Then we have eggs, separate the yolks from the whites. In the dough put the egg yolks, sugar, vanilla sugar, salt, soft butter and whipped in a cool foam proteins at the end. Add the remaining flour into the dough. Knead well with a spoon and put in a warm place to rise. The point is that the dough will not and can not roll out. Due to the small amount of flour cake is surprisingly airy and grows in the oven twice. When the dough has risen, form, lubricated with oil better than sunflower. I put the oiled baking paper. The hand well oiled, and spread half of the dough. Then put the stuffing on the second half of the dough. Smeared with egg yolk, let it rise in the oven for 40-50 minutes on a medium heat.

Here's the beauty of it.
