- This is an Oreo cake I baked 6 years ago! I used a box mix for the cake and store bought frosting. The center has an Oreo cookie filling which was made with vanilla store bought frosting and Oreo cookie crumbs. Now I bake all my cakes from scratch. I am baking another Oreo cake next week totally from scratch and hopefully it will look better with my improved piping and cake decorating skills.
