In a large mixing bowl, beat butter with sugar for a couple minutes until well blended, scraping down the sides of the mixing bowl as needed. Add in eggs, egg whites, and vanilla extract. Beat for 2 minutes.
Alternating additions of the dry ingredients with the buttermilk, slowly add each (about 3 additions of each). After the final addition of buttermilk, beat for one minute then fold in the broken Oreo cookies.
Pour cake batter into the prepared baking dish. Bake for 32-36 minutes, until a toothpick inserted into the center comes out clean. Cool completely.
