01 - Preheat oven to 350°F. Line two baking sheets with parchment paper and set aside.
02 - Whisk together flour, baking soda, and salt in a medium bowl until thoroughly blended.
03 - Beat softened butter with granulated sugar in a large bowl until light and fluffy, approximately 2–3 minutes.
04 - Mix in egg yolks, vanilla extract, and sour cream until fully combined and smooth.
05 - Gradually add dry ingredients to wet mixture, mixing until soft dough forms. Avoid overmixing to prevent tough cookies.
06 - Combine cream cheese, sugar, and vanilla bean paste in a small bowl. Beat until smooth and creamy consistency is achieved.
07 - Scoop approximately 2 tablespoons of dough and flatten into a disc. Place 1 teaspoon of cream cheese filling in center. Fold dough around filling and pinch edges to seal completely.
08 - Place filled cookies seam-side down on prepared baking sheets, spacing at least 2 inches apart. Bake for 11–13 minutes until edges are set but centers remain soft.
09 - Let cookies cool on baking pan for 10 minutes, then transfer to wire rack to cool completely before brûléeing.
10 - Sprinkle thin, even layer of granulated sugar over each cooled cookie. Using kitchen torch, carefully melt sugar until golden and crisp. Let stand 5 minutes before serving.
