• Wrap the dough and flatten it, then refrigerate for at least 2 hours.
• Flour both your work surface and the dough. Spread the dough. It has to be 5 mm thick.
  
• Transfer the dough in a springform pan : grease and flour it before use.
  Spread the dough all over the surface of the pan. Freeze the pan (for about 15 - 30 min : you'll make the flan batter during this time).
• Warm up the milk, cream, vanilla and sugar in a pan. Preheat the oven to 340°F (170°C).
  
• Put eggs, egg yolks and sugar in a bowl. Whisk to combine. Add cornstarch and combine. WHen the milk is hot, pour it gradually while mixing constantly with your whisk.
• Pour this mix in the pan on medium heat and whisk constantly until it begins to boil. Remove from heat and add butter (diced). Combine.
  
• Remove the springform pan from freezer and pour the flan batter inside the cookie dough.
• Bake for 40 minutes at 340°F (170°C), until golden.
  
• Remove from oven and place it on an oven rack. Leave to cool down for 1 hour at room temperature. Unmold on the serving plate and leave to cool down again for 1 hour at room temperature, on a oven rack.
  Then, refrigerate for at least 3 hours, at best 1 night.
• There you are, your flankie is ready !
