Method
For the cake
In a large bowl, beat the egg whites with ½ tsp of lemon juice. Once they’ve begun to foam, add the sugar one tablespoon at a time and whip egg whites until stiff peaks.
In another bowl mix milk, butter, egg yolks, vanilla and the sifted dry ingredients, and stir to combine.
Gently fold both mixtures together without deflating the egg whites.
Pour the batter in two greased 7 or 8 inch pans lined with parchment paper, and bake the cakes in a preheated oven at 160 °C (320 °F) for around 18 - 20 minutes, or until a toothpick comes out clean.
Allow to cool completely.
For the whipped cream
Whip heavy cream, sugar, and vanilla until stiff peaks.
For a sturdier whipped cream you can add 200 g mascarpone.
Tips
Keep in mind the layers are meant to be thin, just like the ones you see in the video.
