Air cake with whipped cream (eclair)

Grease the baking sheet with oil. We lay out the custard dough with a spoon or squeeze out with a confectionery syringe. You can make both round profiteroles and oblong cakes - eclairs. Bake the cakes in the preheated oven for 15-20 minutes at a temperature of 200 degrees. The oven cannot be opened as the cakes may fall. When the cakes rise and brown slightly, reduce the temperature to 160-170 degrees and bake the cakes for another 15 minutes. Then take them out of the oven. We prepare the filling: beat the cream, previously exposed to the ice, with a mixer or whisk in the cold to make a lush mass. By the end of the whipping, add the icing sugar and vanillin to taste. Cut the finished chilled cakes with a sharp knife, removing the top. Fill the cakes with whipped cream, cover with tops and sprinkle with icing sugar.
