I have two nephews with birthdays only 1 week apart, so we're doing something for both this year at the same time. I want to make a square 2 tier cake, and here is my idea:

one likes chocolate and one strawberry so make two cakes of each flavor
cut diagonal in half and use one half strawberry and one half chocolate so that when I put everything together half of the cake is strawberry and turn it around to get chocolate. Does that make sense? And then I'll decorate each side according to the boy. Is this possible? Would I just use buttercream to "glue" the two together? Thanks so much. I hope this can work because I think it would be really cool to do it.

So to make it a little more clear, it's like two cakes in one inside and out.

oh yes it sounds like a great idea, I did the same for a man and women (same birthday) one side girly girly and the other side hunting and fishing, I glued together with bc also and had no problems everyone loved it. Good luck

Cool! I really like this idea! The only thing I'd be worried about is the cake pulling apart. I think if you were doing a single layer cake it would be fine, but the weight of the second tier might cause a problem with the split down the middle. Hopefully someone with more experience will have some tips for supporting the cake.

Anyway, I hope you can do it. It sounds really cool! Post pics when you're done!

I think it's a really cute idea!! You should probably do a bc dam all the way around each half if you're filling them....that way your filling won't ooze out of the center.

A buttercream dam is used to keep the filling in a cake from leaking out the sides. It's just a thick ring of icing piped along the outside edge of each layer that will hold a filling. I learned about using a buttercream dam from CC, too. I tried it for the first time a couple months ago. I posted a picture of it here if you want to see.

this cake is very possible, but heres my concern. If you don't know what a buttercream dam is, this may be beyond your skill. Just a thought. you don't want to promise something and then not be able to deliver.

You can bake both flavors in one pan. Take a piece of card board and place it in the middle of the pan pour one flavor on one side then the other on the other side. pull out the card board. now you have both flavors in one pan and dont have to worry about them falling apart. Hope I explained it ok. good luck

Ladyhawk's idea is great. I have done something like this, but I didn't use a piece of cardboard. I made up the two different flavors of cake batter and got someone to help me pour. We each started pouring our batters at opposite ends of the pan and they met pretty well in the center. It bakes up great just like one cake.

I did this for my twin daughters birthdays. It was fun and very well received.

Sometimes even when baked together, the line where the two flavors meet can separate because of different texture of different flavors. Just so you know.

Since the second tier will be well supported by dowels, straws, plastic colums, or such, the weight of the second layer should not affect the bottom layer. Sounds like an SPS moment to me!!!

Sounds like a great project. Have fun!

they had this one the food network challenge. there were triplets, and one of the cake artists did like a 5 tier cut into thirds. he covered each third seperatley and when he put them back together it looked like big slices. he didn't use anything to stick them back together...

Baking 2 different flavors in one pan sounds like a really cool idea. Though, if it were me, I think I'd do a trial run first. Cardboard + batter sounds like it might be a smidge tricky the first time.

Good luck and post some pictures when you're done! I'd love to see how it turns out!

For the BC dam, Macsmom here on CC posted once she mixes in some cake crumbs to some BC to make a stronger dam. I tried this with a soft filling using bettercreme and it held up amazing! I did not have one blow out. So, that's my new way to do a dam.

There's also a youtube video showing how to bake 2 flavors in one pan:

Sounds like a really cute idea! I recently did a wedding cake with 4 different cake flavors and 4 different fillings for the 'base' of the scene. I took a picture of how I put the base together and dammed it. I had fillings of all different textures from thick to thin. Hope this along with everyone else's advice helps out!
