Preheat the oven to 350°F (175°C).

In a bowl, cream together the softened butter, granulated sugar, and brown sugar until smooth.

Beat in the eggs one at a time, then stir in the vanilla extract.

In another bowl, mix together the flour, baking soda, and crushed chocolate sandwich cookies.

Gradually blend the dry ingredients into the butter mixture.

Fold in the white chocolate chips.

Drop by rounded tablespoons onto ungreased cookie sheets.

Bake for 10-12 minutes or until golden.

Allow the cookies to cool on the baking sheets for a few minutes before transferring to wire racks to cool completely.
