How do you cook a dual layer cake at one time in one pan?

I would like to make a cake with two different cake mixes with the layers being on top of them but only using one pan-- anybody every try this and have tips? I don't want to cook it in 2 pans and put them together-- I would like them to spend a majority of the time cooking together.How do you cook a dual layer cake at one time in one pan?
make sure both cakes will fit in the pan. then, spoon the second cake on top so that it will be as even as possible. kind of like making a marble cake without the swirl.





or you could try a thin layer of flour over the first and then spoon the second.





it would be easier to do side by side then layersHow do you cook a dual layer cake at one time in one pan?

Two different cake mixes?





Just put one in the bottom of the pan, spread it evenly, then pour the second batter over top of that one and spread it out, then bake it. It may marble together a little where they touch. Keep in mind your cake will likely be much thicker that way that it would be if it were just one batter, so the cooking time will be different. If it ends up being nearly twice as thick as the time given is specified for, try lowering your oven temperature about 50 degrees and cooking it for longer, that way it won't burn. If one batter takes considerably longer than the other, start baking that one first, then when it is partially baked, spread the other batter on top of that and put it back in to finish baking so they are both cooked at around the same time.
You could cook both mixes in one deep pan, then when it cools, cut the cake in half to get 2 layers. the problem is, it will turn out like a marble cake. If that is ok, then do it like I suggested. If not, you pretty much have to use 2 pans.
If the cake calls for 2 nine inch pans then I think it would work to cook in a very large round or rectangular pan. It may work sort of like a marble cake, if you mean a layer of chocolate and a layer of vanilla on top. Just add a bit more cooking times to accomodate the larger pan size
