Ingredients
Method
- Heat milk until steaming. Whisk egg yolks, sugar, vanilla, salt, and cornstarch until smooth.
- Temper eggs with hot milk, return to heat, and cook until thickened.
- Remove from heat, stir in butter, strain, cover, and chill for 2 hours.
- Cream butter and sugar until fluffy. Beat in egg and vanilla.
- Add dry ingredients and mix just until combined. Chill dough 30 minutes.
- Preheat oven to 350°F and line baking sheets with parchment paper.
- Roll dough into balls, roll in sugar, and press deep indentations.
- Fill with 1 tsp chilled pastry cream and bake for 9 minutes.
- Cool completely, sprinkle sugar on top, and caramelize with a kitchen torch.
Notes
Caramelize sugar just before serving for the best crackle. Keep torch moving to avoid burning. Pastry cream must be fully chilled before filling cookies.
