# Break the eggs into a deep bowl, add granulated
sugar into it, whisk until it turns to white.
# Add sifted
flour, vegetable oil, baking powder and vanilla into the mixture, mix, and pour it into the square shaped greased baking tray.
# Place it into the oven which is preheated to 320 F for a while, bake it for about 30-35 minutes without drying it.
# Prepare the cream while baking the cake. Put starch,
flour, granulated
sugar and
milk into the pot and mix it well. Cook over medium heat by stirring constantly.
# Remove it from the heat when it reaches to the consistency of
milk pudding, add margarine into the mixture, blend it for a while, and let it cool down. Stir it time to time to prevent butter clotting over the surface.
# After cooling down the cake for a while after removing it from the oven, reverse it onto a paper which is a little bit bigger than the cake. Roll the cake with paper while it is tepid yet.
# Remove the paper carefully when the cake cools down totally.
# Spread the cream to whole surface of the cake which has curve shape a little.
# Place 2 or 3
bananas onto the head side of the cake, and roll the cake with
bananas. Get the end side of the rolled cake to downside.
# If you have some cream yet, spread it over the top. You can sprinkle icing
sugar also instead of cream.
# Refrigerate it overnight, slice and serve.
