A crisp sweet tart crust filled with silky matcha custard and topped with softly whipped cream—an earthy, lightly sweet make-ahead dessert that slices neatly once chilled.

Instructions
In a medium bowl, whisk together the flour, powdered sugar, and salt until no lumps remain.
Add the cold butter cubes and use your fingertips or a pastry cutter to rub/cut the butter into the flour until you have mostly pea-sized pieces with some floury crumbs (a sandy mixture with visible small bits of butter).
Whisk the egg yolk with 1 tablespoon of ice water, then drizzle it over the flour mixture. Use a fork to gently toss and press the mixture together. If it looks dry and doesn’t hold when squeezed, add more ice water 1 teaspoon at a time, just until the dough comes together in clumps.
Tip the dough onto a clean work surface and gently press it into a disk. Avoid kneading.
Wrap tightly (or cover) and chill for at least 30 minutes (up to 2 days).
Preheat the oven to 180°C / 350°F with a rack in the middle.
Lightly flour your work surface and roll the chilled dough into a circle about 28–30 cm (11–12 inches) wide and about 3 mm (1/8 inch) thick.
Transfer dough to a 9-inch / 23 cm tart pan with removable bottom. Ease it into the corners without stretching and press gently against the sides.
Trim the overhang; patch thin spots with scraps. Prick the base lightly with a fork.
Chill the lined tart pan for 15–20 minutes until firm.
Line the crust with parchment paper or foil and fill with pie weights, dried beans, or rice.
Bake for 15 minutes. Remove parchment and weights, then bake 10–15 minutes more, until dry and light golden.
Cool the baked crust completely on a wire rack.
In a medium bowl, whisk together the sugar, cornstarch, and sifted matcha until evenly distributed and no green clumps remain.
Add the egg yolks and whisk until you have a thick, smooth paste.
In a saucepan, combine the milk, 1 cup cream, salt, and vanilla. Heat over medium-low until steaming with small bubbles around the edges (do not boil).
Temper the yolks: slowly pour about one-third of the hot milk mixture into the egg mixture while whisking constantly.
Pour the tempered egg mixture back into the saucepan with the remaining hot milk, whisking as you go.
Cook over medium heat, whisking constantly, until the custard thickens and large bubbles start to surface, about 3–5 minutes.
Reduce heat to low and cook 30–60 seconds more, whisking, to cook out the starchy taste.
Remove from heat and whisk in the butter until fully melted and glossy.
For the smoothest texture, strain the hot custard through a fine-mesh sieve into a clean bowl, pressing gently with a spatula.
Press plastic wrap directly onto the surface. Cool to room temperature, then chill until cold and set, at least 2 hours (up to 2 days ahead).
When crust and custard are both cool, whisk the custard briefly to loosen. Spoon into the tart shell and smooth the top.
Chill the filled tart until fully set and slices cleanly, at least 2 hours (4 hours or overnight for the neatest slices).
For the topping, whip cold heavy cream with powdered sugar and vanilla to soft to medium peaks.
Spread or pipe whipped cream over the tart. Dust with a pinch of matcha and add fresh fruit if desired.
Slice with a sharp thin knife, wiping the blade between cuts.
