01 - Preheat the oven to 350°F. Line 2 baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
03 - In a large bowl, beat softened butter with sugar until light and fluffy. Mix in egg yolks, vanilla extract, and sour cream until fully combined.
04 - Gradually incorporate the dry ingredients, mixing until a soft dough forms. Do not overmix.
05 - Combine cream cheese, sugar, and vanilla bean paste in a small bowl. Beat until smooth and creamy.
06 - Scoop about 2 tablespoons of cookie dough and flatten into a disc. Place 1 teaspoon of the cream cheese filling in the center. Fold dough around filling and pinch to seal. Place seam side down on prepared sheet.
07 - Repeat with remaining dough and filling, spacing cookies at least 2 inches apart. Bake for 11-13 minutes until edges are set but centers are soft. Cool on the pan for 10 minutes, then transfer to a wire rack.
08 - Sprinkle a thin, even layer of granulated sugar on top of each cooled cookie. Using a kitchen torch, carefully brûlée the sugar until golden and crisp. Allow to cool for 5 minutes before serving.
