How to make
Beat the eggs with the sugar with a mixer until whitening, after which, gradually add the oil and the flour mixed with the baking powder, until you get a homogeneous mixture. Pour it into a buttered baking dish, sprinkle it with flour and cook on medium heat until browned.
When it is ready put it on a pre-moistened cloth, smear it with plum jam, or with liquid chocolate and bananas. Roll it up carefully, allow it to cool and sprinkle it with powdered sugar. Enjoy!
