Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a mixing bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.

Add the eggs one at a time, mixing well after each addition. Then mix in the vanilla extract until smooth.

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this to the wet mixture, folding gently until combined.

Fold in the chocolate chunks and any optional add-ins like nuts or cinnamon.

Using a cookie scoop or two tablespoons, drop dough onto prepared baking sheets, spacing them 2 inches apart. Bake for 10-12 minutes until edges are golden.

Let cookies rest on the baking sheets for 5 minutes before transferring to a cooling rack.
