1 and 1/4cupsall-purpose flour
1stick (8 Tablespoons)unsalted butterchilled and sliced
1large egg yolk
3large egg yolks
Make the tart
Place a tart pan with a removable bottom onto a baking pan and set aside.
In a food processor, pulse together the flour, sugar, and salt until well blended. Add in the butter and pulse until the mixture resembles wet sand. Add in the egg yolk, heavy cream and vanilla and pulse until everything comes together into a large mound of dough. If it's too dry, add a dash more cream. If it's too wet, add a little bit of flour.
Knead a few times and flatten into a disc. Wrap in plastic wrap and chill for 2 hours.
Roll the dough out into an 11" circle. Transfer the dough to your tart pan and trim off the excess. Place in the freezer for 10 minutes. Meanwhile, heat your oven to 425 degrees F.
Line the dough with a layer of aluminum foil and place pie weights (or dried beans) on it. Bake in your preheated oven for 20 minutes. Remove the foil and the weights, reduce the oven to 350 degrees F and bake another 8 minutes or until golden.
Make the custard
While the crust is baking, make the custard. In a small saucepan over medium-high heat, whisk together the milk and heavy cream until simmering. Do not allow it to boil. In a separate small bowl, mix together the egg yolks, sugar, and cornstarch. Pour about 1/2 cup of the hot cream mixture into the small bowl and whisk vigorously. Pour the egg yolk mixture into your saucepan and keep stirring until a custard forms. It should coat your spatula or spoon. Remove the pan from the heat and whisk in the butter and vanilla.
Once the crust is baked, remove it from the oven and increase the temperature back to up to 375 degrees F. Pour the hot custard mixture onto the crust and bake for 15 minutes. The custard will be jiggly, and that's OK. Allow the tart to cool completely before serving.
