I made this Oreo Cookie Cake years ago like in 2006. I found the recipe for Oreo cookies on a website somewhere, not sure where at this point. Anyhow, the cookie top and bottom is actually an Oreo cookie. I believe the cookie part was made in a 12inch pan the cake part would of been in a 10 inch pan.
Now at some point in the cooking process it’s possible to write on the cookie part and have it look like it was made that way like an Oreo cookie looks. I put the regular Oreo cookies design all around the outside and then wrote happy birthday Bryan on it.
