Preheat oven to 350°F and line 2 baking sheets with parchment paper.
Measure out your Oreo crumbs, or make your own by finely chopping 3 Oreo cookies, or placing them in the food processor or blender until crumbs form. You can also add the Oreos to a ziploc bag and roll over them with a roll pin until you have fine crumbs. Roughly chop the remaining 5 Oreo cookies and set aside.
In the bowl of a standing mixer with the paddle attachment or a handheld mixer, mix butter and sugars until light in color and fluffy (1-2 minutes). Add in the egg, food coloring and vanilla extract, and beat until just combined. Different brands of food coloring will be darker than others, so start with just 1 teaspoon and add more as needed.
Mix in the dry ingredients until a dough forms. Add in the Oreo crumbs, and crushed Oreos and mix until just combined.
Use a medium cookie scoop or spoon to make 1.5-2 tablespoon sized balls and place them on the baking sheet around 3-4 inches apart. Stick a few more pieces of Oreos on top if desired.
Bake the cookies one sheet at a time for 8-11 minutes. Remove them from the oven when the edges look set. They will look under-baked in the middle!
Leave the cookies on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely. Enjoy!

Notes
Please Note: I highly recommend using a kitchen scale to weigh your dry ingredients. Metric measurements are found above, under the "Metric" tab.Measuring Flour:Be sure to properly measure your flour using either a kitchen scale or by fluffing it up in the bag with a fork, then using a spoon to scoop the flour into the measuring cup and then use the back of a butterknife to level it off (the is the scoop and level method)Food Coloring: Depending on the brand of food coloring you use, you may need less or more than stated above. Start adding it in small amount and adjust as needed.Oreo Crumbs: You can use store bought Oreo crumbs, or you can crush up 6 Oreos into fine crumbs.Gluten Free Variation: To make these cookies gluten free, use gluten free Oreos and replace all purpose flour with gluten free all purpose 1-1 baking flour.Storage and Freezing: Store these cookies in an airtight container for up to 4-5 days.Store baked cookies in the freezer in a freezer bag for up to 2 months. Just let them thaw at room temperature when you’re ready to eat.To freeze the cookie dough, place the cookie dough balls on a parchment lined plate or baking sheet and place in the freezer until they are almost frozen. Transfer the cookie dough balls to a ziploc bag and freeze for up to 2 months. You may need to add an extra minute or two to the baking time!
