Add in your flour and continue to mix together, until just combined. Add in your chopped Oreos and gently fold into your cookie batter. Cover your dough with plastic wrap and chill in refrigerator for 30 minutes.
Preheat your oven to 350 degrees F. Line a large baking sheet with parchment paper. Using a large cookie scoop, place you cookie dough balls onto your prepared baking sheet.
Bake your cookies 9-13 minutes or until cookies are golden brown on the sides. Allow to cook on your cookie sheet for 10 minutes and then place your cookies onto a cooling rack to cool completely. Enjoy
