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