In a large bowl, add the egg yolks, sugar, salt, vanilla, and cornstarch. Whisk until combined and pale-yellow in color. The mixture will be thick initially but will smooth out as you whisk.

Add 1/4 of the heated milk while stirring vigorously. Then, add the remaining milk and stir to combine.

Transfer the mixture back to the saucepan. Heat over medium-low and cook for 8-12 minutes, whisking continuously, until thickened and soft peaks form.

Remove the pastry cream from heat, transfer it to a bowl, and mix in the butter until combined. Place plastic wrap directly on the cream to prevent a skin from forming. Chill in the fridge until fully cold.

Preheat oven to 350°F (180°C). Line two cookie sheets with parchment paper. In a large bowl, whisk together the flour, baking powder, and salt, then set aside.

In a large bowl, cream the butter and granulated sugar using an electric mixer on high speed until fluffy, about 2 minutes. Alternatively, use a stand mixer with a paddle attachment.

Mix in the egg and vanilla on medium speed until the mixture is pale and fluffy, 1-2 minutes.

Slowly mix in the dry ingredients until just combined. Avoid overmixing.

Scoop the dough into balls using a large cookie scoop. Roll into balls. Add sugar to a small bowl and roll each ball to coat.
11 -
Place dough balls onto parchment-lined cookie sheets, slightly flattening each. Bake 6 cookies at a time for 9-10 minutes. Cool cookies on the baking sheet for 5 minutes before transferring to a cooling rack.

Fill a piping bag fitted with a small round tip with chilled pastry cream. Pipe the cream onto each cooled cookie.
13 -
Sprinkle 1 teaspoon of sugar over the pastry cream on each cookie and brûlée with a kitchen torch until golden and aromatic. Let cool for 10 minutes before serving.
