Lemon Star Cookies

Pour the flour, powdered sugar, and baking powder into a mixing bowl with the salt, vanilla sugar, egg yolk, zest, lemon juice, cream, and softened butter. Whisk on low speed until the dough is well combined (and even forms a ball).

Wrap it in plastic wrap and keep it in the refrigerator for at least 1 hour (or even until the next day).

Roll out the dough between two sheets of parchment paper to a thickness of 5 mm, then cut out stars with a cookie cutter. Work fairly quickly before the dough softens. Place them on two other sheets of parchment paper, which are on a baking tray.

Bake each baking sheet for 10 to 13 minutes until the cookies are light golden brown.

For the icing, whisk the powdered sugar with the juice of half a lemon and the egg white. Grate some lime (or lemon) zest on top and mix.

To finish, place the stars on a rack or parchment paper and spread the icing on the cooled cookies using a brush. Allow the icing to set and apply a second layer, or even a third. Let it dry again before storing in a tin.
