Preheat your oven to 350°F (175°C).
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs and vanilla extract, and beat until combined.
In a separate bowl, whisk together the flour, baking soda, and salt, then gradually add this dry mixture to the wet ingredients.
Gently fold in the crushed chocolate sandwich cookies and white chocolate chips until evenly distributed.
Scoop tablespoon-sized amounts of dough onto a lined baking sheet, leaving sufficient space between each scoop.
Bake for 10-12 minutes or until the edges are set but the centers appear slightly underbaked.
Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack.
