Preheat the oven to 350F then line a baking sheet with parchement paper and set aside.
In a food processor, grind the 10 Oreos until finely crushed. In a medium bowl, mix the crushed Oreos, flour, corn starch, cocoa powder, baking soda, baking powder, and salt then set aside.
In a stand mixer bowl, cream the softened butter, brown sugar, and granulated sugar until light and creamy.
Add in the egg, the vanilla, and cake batter extract if using, and mix again until combined. Scrape the bowl when needed.
Add in the dry mixture and mix until the dry mixture disappears. Then using a large cookie scoop, scoop out 8 equally sized cookie dough balls, flatten to about 1 inch in thickness, and freeze for 15 minutes.
Bake the cookies for 11 minutes. Let the cookies cool down fully on the baking sheet.
