Use a food processor to pulse 5 Oreos into fine crumbs; set aside.

In a large mixing bowl, cream the butter, brown sugar, and white sugar until light and fluffy.

Add vanilla, egg, and egg yolk; mix until combined.

Gradually add the flour mixture to the wet ingredients; mix on low until just combined.

Fold in the chocolate chips, Oreo crumbs, and pieces gently.

Cover dough and refrigerate for at least 40 minutes.

Preheat oven to 350°F and line cookie sheets with parchment paper.
