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

In a medium bowl, whisk together the dry ingredients: flour, baking soda, baking powder, salt, and ground cinnamon.

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

Add in the eggs one at a time, mixing well after each addition, then stir in vanilla extract.

Gradually combine the dry mixture with the creamed mixture until just combined.

Fold in the chocolate chunks, and any optional nuts or dried fruits.

Scoop heaping tablespoons of dough onto prepared baking sheets.

Bake for 12-15 minutes until the edges are golden brown and centers remain soft.

Cool on the sheets for about 5 minutes before transferring to a wire rack.
