All that we need.

Egg whisk with sugar.

Add melted margarine.

Then the yogurt. All mix well.

In a separate bowl, sift corn flour and mix it with soda.

Add flour mixture, mix thoroughly.

Baking dish (I have 20 cm in diameter) grease with vegetable oil (the original recipe still needs to sprinkle the bottom with breadcrumbs, I, unfortunately, was not). Pour in the batter, even out. Sent to be baked in the oven, preheated to 180 degrees for 25-30 minutes (readiness check wooden stick). Ready, "the Rich man" take out, allow to cool. Sprinkle top with powdered sugar, cut into pieces.
