In a medium saucepan, heat 2 cups of whole milk over medium heat until it starts steaming, but do not let it boil. Meanwhile, whisk together egg yolks, granulated sugar, salt, vanilla bean paste, and cornstarch in a separate bowl until the mixture is pale and smooth. Gradually incorporate the egg mixture into the hot milk, stirring constantly for about 8-12 minutes until it thickens. Remove from heat, stir in unsalted butter until melted, and transfer to the fridge to cool.

In a mixing bowl, whisk together all-purpose flour, baking powder, and a pinch of salt. In a separate bowl, cream unsalted butter and granulated sugar using an electric mixer on medium speed until light and fluffy, about 3 minutes. Beat in a large egg and a splash of vanilla bean paste, then gradually add the dry ingredients, mixing until a cohesive dough forms. The dough should feel soft and slightly sticky.

Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. Scoop out the dough and roll it into uniform balls, about 1 inch in diameter. Roll each ball in granulated sugar to coat lightly, then place them on the prepared baking sheets, spacing them about 2 inches apart. Gently flatten each ball with the palm of your hand to ensure even baking.

Place the baking sheets in the preheated oven and bake the cookies for 9-10 minutes, or until the edges are lightly golden and the centers are soft but set. Keep an eye on them to avoid over-baking. Once done, remove the cookies from the oven and let them cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely.

Once the cookies are completely cooled, it’s time to assemble your Chewy Crème Brûlée Cookies. Using a piping bag, pipe a generous dollop of the chilled pastry cream onto the center of each cookie.

To create the signature crispy sugar top, sprinkle a thin layer of granulated sugar over the pastry cream on each cookie. Using a kitchen torch, gently melt the sugar until it caramelizes and forms a golden, crackling layer.

Serve your delicious Chewy Crème Brûlée Cookies immediately after caramelizing for the best texture.
