Cut two apples into small cubes and place them in the tray (where you bake the cake) on low heat with 50 g butter and a little sugar to soften. On stewed apples rank biscuits - are not close to each other, and depending on the tray, with random spacing. In the free space between the biscuits put strawberry jam. Then smash the eggs and sugar alternately add the butter, cocoa, baking powder, the chocolate spread and flour mixture a little rarer than cake dough, but this is the aim, because biscuits pour this mixture and after roast cake chocolate mixture is very fluffy and light and very finely combines with biscuits. Bake in a moderate oven for about 30-45 minutes. * This quantity of products is 20-30 cm pan. Because the mixture is more fluid than usual cake batter and less pan to bake it soaks into biscuits.
