A local radio station contacted me for a trade. They want me to make a large cake for a celebration they're having, & they'll give me 21 radio spots. Isn't that Great?
Only thing, they would like 2 12x18 cakes, joined together. I've never joined 2 separate cakes together. They would both be 2 layer, filled. Any suggestions/ tips?
Wow! What a great opportunity! Not only do you get the radio sposts, but lots of people see your work!
I've joined two large cakes before...just make sure they are the same height and make sure the sides where you will be joining them are straight. Push thenm together on the board and ice the entire thing. No one will be able to tell that it was two cakes! Good luck! I would love to have an opportunity like this!
Thanks, I did think of the plywood, because that's really going to be a heavy cake. I'm really excited about this opportunity. But, so many decisions. They want to know when I want my spots - all now, spread out, so many at different occasions, etc. I never really thought about all of that.
Congratulations! Free advertising is always a good thing!!!
I agree with the other posts. Make sure you use something like plywood. I have used it before and when I covered it I attached the covering (colored foil) with a small heavy duty stapler...worked like a charm!
Don't forget to post pics!!!!

OMGosh! Awesome opportunity! Congrats!
I have put two cakes together like this.. the board on the bottom does need to be sturdy or the icing will crack. And its an awkward cake so the sturdy bottom helps when moving the cake. I always do them like jen1977 says I push them together & icing the entire thing.
You will do fine! 
Congrats on the awesome opportunity! As the others have said, use plywood or MDF under the cakes. I've always just pushed the cakes together. As long as they're the same height and the sides are straight (may need to trim a little), the seam will be unnoticeable.
Most important thing is - this cake will be HEAVY! And, unlike a wedding cake, where the weight is all in the center, the weight on your cake will be spread out wide. Whenever I do a cake this size, I have to make sure someone other than me is available to carry the cake.
