Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
In a large bowl, beat the softened butter and cream cheese together until smooth and creamy.
Add the brown sugar and granulated sugar to the butter mixture and beat until well combined.
Mix in the egg and vanilla extract until fully incorporated.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the chocolate chips until evenly distributed throughout the dough.
Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes, or until the edges are lightly golden but the centers are still soft.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
