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

In a medium bowl, whisk together flour, baking soda, baking powder, salt, and ground cinnamon until well combined. Set aside.

In a large mixing bowl, beat together softened butter, brown sugar, and granulated sugar until light and fluffy.

Add eggs one at a time, mixing well after each addition, then pour in vanilla extract and mix until smooth.

Gradually add the dry mixture to the wet ingredients, mixing on low speed until just combined, being careful not to overmix.

Gently fold in chocolate chips and any optional mix-ins like nuts or dried fruits.

Drop generous amounts of dough onto prepared baking sheets, leaving space between each mound.

Bake in the preheated oven for 12-15 minutes until edges are golden and centers are soft.

Let the cookies cool on the sheets for 5 minutes before transferring them to a wire rack to cool completely.
