Prepare the Dough

1. Cream Butter and Cream Cheese: In a large mixing bowl, use an electric mixer to beat the softened butter and cream cheese until smooth and creamy.
2. Add Sugars: Mix in the granulated sugar and brown sugar, beating until light and fluffy.
3. Incorporate Egg and Vanilla: Add the egg and vanilla extract, blending until well combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
5. Fold in Chocolate Chips: Gently stir in the chocolate chips with a spatula, ensuring they’re evenly distributed.

Chill the Dough

1. Refrigerate: Cover the bowl with plastic wrap and chill the dough for at least 30 minutes. This step helps the cookies maintain their shape during baking.

Bake the Cookies

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
2. Scoop Dough: Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
3. Bake: Bake for 10-12 minutes or until the edges are lightly golden.
4. Cool: Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
