Preheat the oven to 180°C (350°F).
Roll out the tart crust and place it in a tart pan.
Poke holes in the crust with a fork to prevent bubbling.
Bake the crust for 15 minutes until golden brown.
While the crust cools, heat the milk in a saucepan.
In a bowl, whisk egg yolks, sugar, and cornstarch until smooth.
Pour the heated milk over the yolk mixture, whisking constantly.
Return the mixture to the saucepan and cook until thickened.
Remove from heat and stir in butter and vanilla extract.
Pour the pastry cream into the cooled crust and refrigerate until set.
Arrange halved strawberries on top for decoration.
Brush with gelatin or glaze if desired for shine.
