This could be my favorite dessert of all time. It’s exceptionally tasty!
Line the tart shell with parchment paper, fill with baking beans, and blind bake for 15 minutes. Remove the beans and paper, then bake for another 10 minutes. Let it cool completely.
For the filling, heat the heavy cream and milk in a saucepan over medium heat until just simmering. Remove from heat and add the chopped white chocolate, stirring until melted and smooth. Stir in the vanilla extract.
