For the cake
4 Egg yolks
6 Egg whites
150 g (¾ cup) Sugar
160 g (⅔ cup) Milk
60 g (4 tbsp) Oil or melted butter
180 g (1 cup + ¼ cup) All purpose flour

Method
For the cake
In 1 bowl, beat the egg whites, with ½ tsp of lemon juice. Once foamy add the sugar one tablespoon at a time and whip egg whites until stiff peaks.

Gently combine both mixtures together without deflating the egg whites.
Pour the batter onto two cookie sheets, greased and lined with parchment paper, and bake cakes in a preheated oven at 170 °C (340 °F) for 10 - 12 minutes, or until a toothpick inserted in the center of the cake comes out clean.
Allow to cool completely.

In a large bowl, mix the mascarpone, heavy cream and powdered sugar.
Add the vanilla extract (optional).
