To start preparing the biscuit. I make this recipe (in the slow cooker-pressure cooker) http://www.povarenok .ru/recipes/show/101 467/. Beat with a mixer eggs (room temperature to let the sugar dissolve faster) with sugar and salt for about 8 minutes. Weight needs to brighten, increase in volume. Flour screened with baking powder and injected into the egg mixture, gently stirring with a spoon (not a mixer) from the bottom up, the mass is not settled. Grease the bowl multivarki butter and pour it dough. Put on the "Baking" on 35 minutes. If you cook in the oven 25-30 minutes at 180 degrees.

With the cooled sponge cake cut the tip and gently pull out the middle, leaving the sides (as pictured). The upper and middle, tear into pieces (not too small but not large))

Bananas to clear, cut slices. Spread the bottom of our billet - it took me 2 bananas.

Whisk sour cream with sugar, add the remaining 2 finely chopped banana and a biscuit, we pre-broken))) mix Everything together, but carefully, so weight is not turned to mush.

The resulting mass lay out in our biscuit base for bananas, lightly stamped. Pour melted chocolate, decorate to taste))) be Sure to give the cake to soak, preferably overnight. All the cake is ready. Turned out very juicy and fresh))) unfortunately, in the context sfotkat not have time, too quickly, my cake was destroyed by the guests)))
