Preheat the oven to 170°C (338°F).
Take the large chocolate tart dough out from the freezer and place it on a baking pan.
Poke the bottom of the dough several times with a fork.
Press down the dough with parchment paper and baking beans or similar weights to prevent puffing.
Bake in the preheated oven for 20 minutes.
Let the tart shell cool.
