Preheat the oven to 180°C.

1. In a double boiler, melt the chocolate and add the butter, then mix outside the heat to incorporate.

2. In a bowl, beat the eggs and add the sugar.

3. Sprinkle with flour and mix.

4. Combine all the ingredients and transfer everything to a buttered and floured tart mold.

5. Bake for 15 to 18 minutes. The center must remain tender without being soft. Let it cool down.

6. Meanwhile, whip the milk with vanilla and refrigerate.

7. Serve a bit of set vanilla milk mousse on the tart.

A delight!
