In a large mixing bowl, cream together the butter, cream cheese, brown sugar, and granulated sugar until smooth and fluffy.
Mix in the vanilla extract and egg until well combined.
In a separate bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the chocolate chips evenly throughout the dough.
Cover and refrigerate the dough for at least 1 hour to enhance flavor and texture.
Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
Use a cookie scoop to portion out dough onto the baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes or until the edges are golden brown.
Allow cookies to cool on the baking sheet for a few minutes before transferring to a cooling rack.
