sheet cake

[pirandellian]

does anyone know how to make a "half and half" sheet cake? I have an event coming up on Sunday that I said I'd make a cake for. I'd rather do it half vanilla and half chocoalte. But I don't want to make two cakes.

Help!

DD1 and I made a 1/2 vanilla and 1/2 chocolate cake once. We made the two different batters and then she poured one on the right side of the cake pan while I poured the chocolate into the left side of the pan. There wasn't a neat, clean division in the middle, but that worked fine for us.
