Separate eggs into whites and yolks, whites put into the refrigerator. And turn the oven on 170-180 degrees, it should be well preheated.

Dry ingredients mix in the following order: flour, sugar, starch, salt, baking powder. Do the deepening and pour in the oil, water, yolks, add the vanilla.

Beat chilled whites with citric acid until stable peaks.

Gently mix yolk mixture with proteins, until smooth.

Prepare a form, grease the bottom with vegetable oil, cover with baking paper, grease sides of 1 cm the Dough pour in the form, and carefully put in oven, the oven door did not clap, and then maybe settle down. And bake at a temperature of 170-180 degrees 50 minutes to an hour. Readiness check by clicking on the biscuit if when you push the biscuit from taking the initial odds to finish. I still check just in case a wooden stick for BBQ if dry - ready.

Remove from oven, let stand in the form of 5 minutes, with a knife to pry the edges and pull out of shape. Allow to cool completely on the grill, I turn the cake to cool down faster.

Cut into 2 or 3 pieces at will, this time I cut in three parts. And collect the cake, the cream what you want to wish your favorite, I prefer to do iogurte fruit or berry souffle.
