Cream the Butter and Sugars: In a large bowl, beat the softened butter, brown sugar, and white sugar together until creamy, about 2 minutes.
Add Wet Ingredients: Mix in the egg and vanilla extract until fully combined, scraping down the sides of the bowl as needed.
Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt.
Incorporate Dry Ingredients: Gradually add the dry ingredients to the wet mixture, mixing half at a time until well combined.
Add Chocolate Chips: Stir in the chocolate chips until evenly distributed throughout the dough.
Chill the Dough: If the dough feels too soft, cover the bowl and refrigerate for 20 minutes.
Prepare for Baking: Preheat your oven to 350°F (175°C) and line two baking trays with parchment paper. Scoop the dough onto the trays, spacing them about 3 inches (7.5 cm) apart.
Chill the Shaped Dough: Refrigerate the cookie dough balls for an additional 30-40 minutes before baking to ensure thicker cookies.
Bake: Bake the cookies for 10-12 minutes, or until the edges are lightly golden. The centers should still look slightly soft.
Cool and Serve: Allow the cookies to cool on the baking tray for a few minutes before transferring them to a wire rack to cool completely. Enjoy!
