How do you bake a half chocolate/half yellow cake? (or whatever 2 flavors of choice are)

Do you bake one chocolate, one yellow and then cut in half and stack? Or do you bake in the same pan?

I'm wanting to bake in the same pan, b/c every time I do the cut half/half and stack my icing seaps in the middle.

I'm using a 11X15 pan.

Thank you!

Yes I bake in one pan and just pour both batters at the same time on opposite ends of the pan

I pour both in one pan. I use heavy duty foil, folded over a couple of times to make a strip to seperate the pan in the middle, then just pour the batter. After adding the batter I remove the strip of foil.

THANK YOU!!!!!!
