Tarte au Sucre is a speciality from Northern France, the city of Lille and its surroundings. Though it is called a tart, it is more akin to a sweet pastry. It ressembles a brioche with a sugary creamy filling. Tarte au Sucre is very much sweet comfort food, a very comforting note to the end of a meal, or anytime of day.
My source of inspiration was a French recipe from a fellow blogger who is originally from the city of Lille.
