Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.

1. In a large bowl, cream together the butter, cream cheese, granulated sugar, and brown sugar until light and fluffy.
2. Beat in the egg and vanilla extract until well combined.
3. In a separate bowl, whisk together flour, baking soda, and salt.
4. Gradually mix dry ingredients into the wet ingredients until just combined.
5. Scoop dough into 1.5 tablespoon-sized balls. Flatten each slightly and press a caramel candy into the center, then wrap the dough around it to seal.
6. Place dough balls seam-side down on the prepared baking sheet, spacing a few inches apart.
7. Bake for 10–12 minutes, until edges are set and centers are soft.
8. Cool on pan for 5 minutes, then transfer to a wire rack to cool completely.
9. Drizzle with warm caramel sauce and sprinkle with sea salt if desired.
