Preheat oven to 250° degrees.

Mix egg yolks and heavy cream, slowly add the sugar and salt. Scrape vanilla bean and add to the mix. At last add the sifted flour.

Now heat the mixture in a saucepan and let it boil until it thickens.

Take a muffin tin and oil it. Roll out the puff pastry and cut out circular shapes (about 15 cm). Press into the prepared muffin tin, don’t forget to form a spread around the bottom as well as the edges. Spread with brown sugar on top (that will caramelize during baking process).

Pour in the prepared egg-mixture. Bake for 12-14 minutes. Best served warm.
