In a mixing bowl, combine flour, butter, and powdered sugar until crumbly. Add egg yolk and mix until dough forms.

Press the dough into a tart pan and chill for 30 minutes.

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

Preheat the oven to 350°F (175°C). Fill the crust with the fig mixture and bake for 45 minutes or until golden.

Let cool before serving.
