Cake due for tomorrow, after 9pm and I need to start baking!! (long story on why so late). Anyway, I am making an 11x15 sheet that needs to be 1/2 white and 1/2 chocolate, not marbled. how to do? Can I somehow pour the batter in opposite sides at the same time or what? Can 1 person do this? I am really in a panic now. Thought I had a handle on it!

HI

I had an order exactly the same. I just baked on sheet cake chocolate and one white, then cut them in half and stacked the chocolate on top of the chocolate etc. I used icing to glue them together. It worked great and everyone loved the cake. Hope this helps

You could put a piece of wax paper, parchment paper or aluminum foil in the middle. Fill each side at the same time. When both flavors are in the pan you could pull the paper from the middle. Then you will have chocolate and vanilla.
Good luck

I have done this many times just by pouring both batters at the same time. So many people have told me how much they love the piece in the middle!! The best of both worlds. Hope it turned out well for you!

Funny you ask this I am doing this exact cake size and all at this moment. I poured the two batters in at the same time. However, I noticed when I take them out they are sort of splitting where the two meet in the center. Weird!! So I am not sure what to do at this moment. I wrapped them in saran wrap and am hoping when they cool in the fridge they meld together.
Hmmmmm......

I do this quite often with no trouble. At first I had my husband help me 'cause I wasn't confident that I could do it by myself. But after a while, I got the hang of it and just poured them in....sometimes at the same time or usually the choc. first since it seems to be thicker and gives me more time, then the vanilla. Make sure to start in the middle if pouring at the same time. Good luck.
