Have you heard about magic cakes ? With only one mix, you will get three different layers : flan, cream and sponge cake.
Maybe you think that this recipe is long and difficult, but it's the easiest !
Heat the milk with the vanilla pod and brew for 15 minutes at low heat. Melt the butter
Whisk the egg whites
In a bowl, beat the yolks with sugar until creamy
Add butter and mix
Add the milk gradually
Then add flour and lemon peels
Finally, gently add egg whites with a spatula
Pour the mix in a previously greased cake pan, and smooth the top with a spatula. Bake for 50 minutes at 300°F Leave at room temperature for 1 hour, then put it in the fridge for 2 hours before gently unmold it. It's a very important step since the layers are going to form while cooling.
