12x18, 1/2 chocolate 1/2 white, torted & filled with fluffy vanilla cream on one side & hint of orange on another. Fun cake to make! Picture doesn't do the black justice. Used Americolor Black, WOW, was it REALLY black! Thank you TAT for letting me use your design!! (R.I.P. is a sugar tombstone says "Really Into Partying") Cake was a big hit.
