Preheat the oven to 350°F (175°C). In a mixing bowl, combine flour, butter, and powdered sugar until crumbly. Add egg yolk and mix until dough forms.

Press the dough into the bottom and up the sides of a tart pan. Prick the bottom with a fork.

Bake the crust for 15 minutes or until lightly golden. Remove from oven and let cool.

In a bowl, mix sliced figs, chopped hazelnuts, honey, and vanilla extract until well combined.

Pour the filling into the cooled crust and spread evenly.

Bake for an additional 30 minutes or until the filling is set.

Allow the tart to cool before slicing. Serve at room temperature.
