Preheat oven to 350°F (177°C). Mix the flour and baking soda in a bowl and set aside. With an electric mixer or stand mixer with a paddle attachment, cream the butter, cream cheese, and sugars together. Add the egg and vanilla and mix well. Gradually add the flour mixture and stir until a dough forms (may take a couple minutes of stirring). Fold in the crushed Oreos.

Chill dough for at least 1 hour or up to 5 days in the refrigerator.

Scoop 2 Tablespoons of dough for each cookie. Roll it into a ball. The cookies are rather large, but if you’d like them smaller, make each dough ball only 1 Tablespoon. Drop dough ball onto a baking sheet lined with a silicone baking mat or parchment paper. Make sure the balls of dough are tall. Do not flatten them. Bake for 10-11 minutes or until edges are slightly browned. The centers should appear soft and puffy. Allow to cool on the baking sheet for 5 minutes before moving to a cooking rack. Cookies stay fresh at room temperature for up to 7 days.
