1. In a small bowl, mix the cream cheese, powdered sugar, and caramel sauce until smooth. Scoop into small portions and place them on a lined tray, then chill until firm.

2. In a medium bowl, whisk together the flour, baking soda, and salt.

3. In a large bowl, beat the butter, brown sugar, and granulated sugar until light and creamy. Mix in the egg and vanilla extract.

4. Gradually add the dry ingredients to the wet ingredients and mix until a soft dough forms. Fold in the caramel bits if using.

5. Scoop portions of dough and flatten each one slightly. Place a chilled cream cheese filling portion in the center, then wrap the dough around it and seal the edges.

6. Place the filled dough balls on a tray and chill for 20 minutes.

7. Bake at 350°F for 11 to 13 minutes, until the edges are lightly golden and the centers are just set.

8. Cool on the baking sheet for 5 minutes, then transfer to a wire rack. Drizzle with extra caramel sauce once cooled.
