Make the Shortbread Crust
- In a food processor, pulse the flour, powdered sugar, and salt. Add the cold butter and pulse until the mixture resembles coarse breadcrumbs.
- Whisk the egg yolk and vanilla, add to the processor, and pulse just until the dough comes together. Form into a disc, wrap, and refrigerate for 30 minutes.
- Preheat oven to 375°F (190°C). Roll the dough into a 12-inch circle and fit it into a 9-inch tart pan. Freeze for 15 minutes.
- Line the tart shell with parchment paper and fill with pie weights. Bake for 15-20 minutes. Remove weights and bake for another 10-12 minutes until golden. Let cool completely.
Prepare the Eggnog Pastry Cream
- Heat the milk, heavy cream, and eggnog in a saucepan until simmering.
- In a large bowl, whisk together egg yolks, sugar, cornstarch, and salt until pale and thick.
- Slowly whisk about half of the hot milk mixture into the egg yolk mixture to temper it. Pour the tempered mixture back into the saucepan.
- Cook over medium heat, whisking constantly, until the custard thickens and boils for 1 minute. Remove from heat.
- Whisk in the butter, vanilla, nutmeg, cinnamon, and optional rum until smooth.
Assemble and Chill
- Pour the warm pastry cream into the cooled tart crust and spread evenly.
- Press plastic wrap directly onto the surface of the cream and refrigerate for at least 4 hours, or until firm.
- Garnish with freshly grated nutmeg before serving.

Notes
Tip 1: To ensure a crisp crust, you can brush the bottom of the fully baked tart shell with a thin layer of beaten egg white and bake for 2 more minutes. This creates a waterproof seal.
Tip 2: Strain the pastry cream through a fine-mesh sieve before pouring it into the tart shell for an extra-silky smooth texture.
Tip 3: Let the tart sit at room temperature for about 15-20 minutes before slicing to take the chill off for the best flavor and texture.
