How Do I Make A Full Sheet Cake At Home?
Decorating By amyhntr2 Updated 12 Sep 2012 , 5:04am by cuppyc8kes

Hi everyone I'm brand new.
I need to make a fondant covered full sheet cake for someone and I've never made one that big before. She's wants it to be 18x24". (I'm seeing conflicting information on the actual size of a "full sheet cake" period. Is it 18x24?)
Anyways. That probably won't fit in my regular kitchen oven right?
How do you all do it? Do you make two half sheets and put them together? Are you able to see the seam underneath the fondant if you do it that way.
Thanks for any advice!

yes bake two halves and put together.
can glue seam with BC or melted chocolate
very STRONG and INFLEXIBLE cake board underneath -- flexing of the support board will be the reason a seam would show.
once iced in BC and then covered in fondant the seam won't show -- unless the support board flexes.


most full sheet cake boards/boxes won't hold 2-12x18's together (trust me I know lol) I do make them however, and what I do is cut about 2" off the 18" side and then seam them into the center of the cake, you wind up with a 1" cube that won't fit anywhere, i usually throw it at one of my kids and continue with the cake.
Make sure you put a good amount of icing in the seam where the cakes will join together...I put lots and then push the cakes together as firm as you can allowing some icing to smoosh up and on top of the cake. Then when it's all smoothed out you can't tell.
If you can see the seam with your buttercream, you'll see it with your fondant.
Also, if you don't use a sturdy enough board underneath the cake when moving it the cake will crack right down the seam!! NOT GOOD!!

Not sure if this is the right place to ask this question, if you seam two cakes can you stack on top of them?


Two 12x18's make a full sheet.
Two 11x15's is NOT a "full" sheet.
If you seam two 12x18's together, you have a single layer 18x24. There is no reason you can't stack something on top of this ..... just like you would put any other cake on top of any other single layer cake. I've done it too many times to mention.


Yes, I gree as well. I always use 2-12x18s when a customer ask for a FULL sheet cake. Its easy to combine the two cakes to seem as if they are one. Just make sure that both have been leveled to the same hieght before seaming and icing together. Also, someone spoke on support. It is a must that you have good support!! Good Luck!

I agree with others. I consider a full sheet cake 2- 12X18's put together. I just did one last weekend. My local cake/candy store had boards and boxes that were 20X26. They worked out perfectly.
that's the size boxes I get but I find it's just too tight of a squeeze having less than 1" on the front and back of the cake, doesn't leave much room for a border without everything smooshing into the box.
Actually you know what?? I think mine is 18x25 (my box)...no wonder they don't fit for me! lol

Hello I have a cake to do this weekend...the client wants a full sheet covered in black fondant. I tried to suggest a tiered cake, but they are set on a full sheet. I am worried about leveling evenly and covering such a big cake in fondant. Does anyone have any great tips? Thank you I appreciate the advice and your help.
