How to make
Beat the eggs, sugar, oil, flour and baking powder well, then bake the mixture on a baking sheet in a preheated oven at 360°F (180 °C) for 30 min (depending on the oven).
As soon as the layer is ready, immediately turn it over on to a damp cloth and roll it up. Wait a few minutes and smear it with jam.
Sprinkle it with powdered sugar or chocolate sprinkles and serve.
