Heat the oven to 180C and line a 23 cm square baking pan with baking paper; mix the flour, baking powder and salt.
Beat the egg whites to soft peaks, then gradually beat in the sugar until glossy; beat in the yolks one at a time.
Fold in the flour mixture in two additions, alternating with 60 ml of the milk and the vanilla, keeping as much air as possible.
Spread the batter in the pan and bake for 25-30 minutes until golden and springy; cool for 10 minutes in the pan.
Whisk the evaporated milk, condensed milk and the remaining 120 ml of milk; prick the warm cake all over with a fork and pour the mixture over it slowly so it soaks in.
Cover and refrigerate for at least 4 hours or overnight.
Whip the cream with the powdered sugar to soft peaks, spread it over the cake, dust with cinnamon and cut into 9 squares.
