2 thin layers of dough to spread sales of sugar and powder jelly egg whites. For the protein foam to put 2 /3 peeled apples, cut into slices (2 -6 mm, depending on softness of apples). On the third layer of dough spread the remaining 1/3 of the Apple slices, sprinkle with sugar. Over the apples on each cake to put a layer of puff pastry.

Three layers that we got baked in the oven (180 degrees) until slightly Golden yellow color (approx. 20 min the cake without protein; 30 min at cakes with protein foam that I baked close on 1 baking sheet) ...From scraps of dough make crumbs for dusting the cake.
