Preheat the oven to 375 degrees F. Prepare an 11-inch round fluted flan
baking pan by spraying it with flour-infused oil.

to beat the eggs and sugar together until the egg mixture has become very thick
and turned a very pale yellow.
Sift the flour and baking powder together. Use a large spoon or spatula to fold
the flour into the egg mixture, one third at a time.
Pour the sponge mixture into the prepared flan dish. Use a spatula to spread it
Bake in the pre-heated oven for 25 minutes until the top is golden brown.
Cool for 2 minutes before inverting on a wire tray to cool completely.
Decorate with freshly whipped cream and fruit of choice.
