In a large mixing bowl, cream together butter, granulated sugar, and brown sugar until light and fluffy. Add eggs one at a time, mixing well after each. Stir in vanilla extract. In a separate bowl, whisk together flour, baking soda, and salt. Gradually mix dry ingredients into wet ingredients. Chill dough for 1 hour.

In a medium bowl, beat cream cheese until smooth. Add sugar, egg, and vanilla extract. Beat until well combined and creamy.

Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper. Scoop a tablespoon of chilled cookie dough and flatten it into a disk. Place a spoonful of cheesecake filling in the center, fold the edges over to seal, and roll into a ball. Arrange on the baking sheet, spacing 2 inches apart.

Bake for 10-12 minutes or until edges are lightly golden. Cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Melt white chocolate chips in a microwave-safe bowl in 30-second intervals until smooth. Drizzle melted white chocolate over cooled cookies and sprinkle chopped Reese's peanut butter cups on top. Allow the topping to set before serving.
