In a bowl of a stand or electric mixer, add the butter and sugar and whip it on high speed for 5-8 minutes until they are properly creamed together.
Once that's done, add the eggs and whip on medium-high speed until there are no liquid streaks left in the batter and the eggs are properly incorporated in the batter.
Turn the mixer down to a slow speed and gradually start adding the flour. Mix until the flour is just incorporated into the dough. Make sure not to overmix, or your dough will become too sticky. The final dough should just hold its shape together.
Transfer the dough to the baking paper, then place another sheet of baking paper on top. Roll the dough to 2mm thickness evenly, then let it chill in the freezer for 15 minutes. Freezing the dough allows it to hold its shape when you shape it around your tart ring or pan.
After chilling, cut and shape the dough as per your tart ring, then chill it for another 15 minutes. If you are not using a perforated tart ring, poke small holes on the base of the pastry with a fork to allow even baking. The holes also stop the pastry from rising while baking.
Place baking paper on top of the prepared tart ring, then fill it with dry rice or baking beans. Adding weight to the pastry allows it to bake without rising.
Preheat the oven to 160 degrees Celcius, then blind bake the tart for 15-20 minutes or until golden brown. Bigger tarts might take a longer time.
