Step 1: Prepare the Dough

1. In a large mixing 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 fully incorporated.

Step 2: Combine Dry Ingredients

1. In a separate bowl, whisk together the flour, baking soda, and salt.
2. Gradually add the dry ingredients to the wet mixture, mixing until just combined. Avoid overmixing to maintain a soft texture.

Step 3: Add Chocolate Chips

1. Gently fold in the chocolate chips, ensuring they’re evenly distributed throughout the dough.

Step 4: Chill the Dough

1. Cover the dough with plastic wrap and refrigerate for at least 1 hour. Chilling helps prevent the cookies from spreading too much during baking.

Step 5: Preheat and Portion

1. Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
2. Use a cookie scoop or tablespoon to portion the dough into 1.5-inch balls. Place them 2 inches apart on the baking sheets.

Step 6: Bake

1. Bake the cookies for 10–12 minutes, or until the edges are lightly golden. The centers will look slightly underbaked but will firm up as they cool.
2. Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
