Preheat the oven to 350°F (175°C).

Line a baking sheet with parchment paper.

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

Add the eggs one at a time, mixing well after each addition, followed by the vanilla extract.

In a separate bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Gently fold in the crushed chocolate sandwich cookies and chocolate chips, if using.

Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake for 10-12 minutes until the edges are golden brown but the centers remain soft.
