Sift flour, powdered sugar, and a pinch of salt into a large mixing bowl. Cut the cold butter into the mixture using a pastry cutter until it resembles coarse cornmeal. Add egg yolks and vanilla extract and mix until just combined. Form the dough into a ball, divide it in half, wrap in plastic wrap, and chill for at least 1 hour.

Roll out one ball of dough into a round shape about 1/4 inch thick. Drape the dough into a tart tin and press gently into the sides without stretching. Remove excess dough by rolling over the top with a rolling pin. Poke the bottom of the crust with a fork without piercing through.

Repeat the rolling, shaping, and trimming process with the remaining dough to make a total of four tart crusts. Chill tart tins for 15 minutes in the fridge while preheating the oven to 375°F.

Line the chilled crusts with aluminum foil and add pie weights. Bake for 10 minutes, remove the foil and weights, and bake for another 5 minutes until golden brown. Let cool completely before filling.

In a small pot, smash fresh blueberries with a whisk or fork. Add heavy cream and warm over low heat while mashing until the mixture turns purple and begins to bubble (about 10 minutes). Strain the mixture through a mesh sieve into a bowl containing white chocolate chips. Mix until smooth and let cool to room temperature.

Spoon the cooled blueberry ganache into the cooled tart crusts. Place the tarts in the freezer for at least 3 hours or overnight to set.
