Preheat the oven to 350 F and prepare two baking sheets by spraying with cooking spray. Set aside.

In a small bowl, combine the flour, cocoa, baking soda and salt. In a large bowl, use an electric mixer to beat together sugars, butter, and vanilla. Add the eggs, one at a time. Then gradually stir in the flour/cocoa mixture. Fold in the chocolate chips.

Use a cookie dough scoop about 12 balls of dough and place on baking sheets. Slightly flatten the cookie dough balls, and place a couple of Hershey's Cookies N Creme pieces on it. Then, scoop another ball of dough for the "top" of each cookie, pressing around the sides so that the Cookies N Creme bar is stuffed in the middle. Bake cookies for about 10-12 minutes (bigger cookies will take longer). Press another Hershey's Cookies N Creme piece on the top of each cookie, and sprinkle with crushed Oreos. Let cookies cool for about 10 minutes on the baking sheet before serving. Enjoy!
