Preheat the oven to 350°F and line two baking sheets with parchment paper.
In a large bowl, beat the butter and cream cheese together until smooth.
Add the sugars and mix until light and fluffy.
Mix in the egg and vanilla extract until fully combined.
Sprinkle in the baking soda and salt, then slowly add the flour. Stir until just mixed.
Fold in the chocolate chips evenly throughout the dough.
Use a cookie scoop or tablespoon to place dough balls on the baking sheets, leaving room to spread.
Bake for 9–11 minutes, until the edges are set and the centers are still soft.
Cool on the baking sheet for 5 minutes, then move to a rack to finish cooling—or eat one warm!
