I am making a replica of a house cake...the dimensions are 12x12x15. It is basically a solid cube of cake. I am going to have boards in the center and pvc dowls for support as well as a PVC center dowel support. Hoping that is good support wise. But how many servings would you say if I cut it wedding cake style? I am nervous on so many levels for this cake! I have to drive it 1 hour away fully assembled of course. Then to top it off I have to cut it in front of 255 people. I am wondering if that will feed the crowd or do I need a sheet cake on the side? Any adive would be welcomed!

So 12" high?

If so basically you'll have 3- 4" high 12 x 15" cakes stacked solid correct?

Based on Wilton's wedding chart a 11 x 15" serves 74 so 74 x 3 (cakes) =222 servings.

Of course you'll have to account for all of the dowels and supports taking away some servings, it'll be close.

a 12 inch cake serves 72 (wilton wedding). say your 'tiers' are 3 inches high, 15 inches height total = 5 'tiers'. total servings = 360.
sounds fine to me!
looking at the other respone, it depends how you read the dimensions!

I guess I did not describe it well. It will be a 12x12 square that is 15 inches tall. It will be between 4-5 tiers tall but all solid not decreasing in size. I have to frost it as a solid cube and then to cover each "wall" in fondant I am hoping that it does not slip and wrinkle at the bottom. I am going to start the construction of the cake today because I have alot of detail work to do once it is assebled. I can not make them ahead because I am afraid the scale will be off on the windows and shutter sizes. Then there is a side porch and that is a whole different story! I didn't hink of deducting for the dwels and such. I guess I should make a sheet cake on the side. Do you think from what I have said support wise does it sound stable?

Oh OK now I understand....Wow, that's going to be fantastic please post pictures when you're finished I can't wait to see it.

I've never done anything that tall all in cake/fondant before so I really can't advise on the construction or support, sorry.

But, as far as the # of servings I would say as long as each "tier" or cake is at least 3-4" tall, you should be able to get 72 servings out of each 12" sq. So if you have 4 cakes that would be 288 servings or probably 275 if you subtract some servings due to the supports/pipes.

Good luck!

P.S. Any chance you could talk them into a Rice Krispy Treat house and sheet cakes to serve? It would be a lot more stable and they could save it for a while. Just a thought for ya!

12 x 12 x 15 = 2160

(Adjusting the serving dimensions so that it will divide evenly, still getting about the same amount of cake as in the standard 1x2x4 serving).

1 x 2.66 x 3 = 7.99

2160 / 7.5 = 270

(2.66 = 2 and 2/3 inch)

Yeah, 270 servings. Sorry, I meant to type that out as a summation sentence, but hit submit too fast.

I saw Duff make a Firehouse cake once with brick (fondant) walls. The episodes are available to watch online now--maybe you could take a peek and see how he made his--it was huge and the walls didn't slide at all.

Thanks for the info...I will surely post pictures I am hoping it turns out well! It is a replica of the Juliette low house who is the founder of girl scouts. Her birthday is Oct 31st so it is a huge GS event and my cake is the focus of the whole event...EEEKKKK!!! I hope I didn't bite off more than I can chew! Oh yeah and I have to cut and serve it in front of these 255 people...did I mention that I have NEVER cut a cake this large in my life?? Oh dear god please pray for me!!!

Here is the final cake! I am so happy how it turned out! Let me know what you think! The final cake was 12x12x15. plus the side porch. The front steps are RKT covered with fondant.

Wowwwww. Wonderful workmanship. Solid construction--so well done.

Beautiful piece.

It's beautiful!!!!

Wow!! That is stunning!

So, how did you cut it?

The cutting went well! It was basically a 4 tiered cake with boards in between so i just cut from the top down to the board then cut through the fondant at the bottom of the row of slices and the cut just like any square cake. Everything went so well and I was nervous for nothing and now i have a huge cake under my belt!

I"ll say!!! That is THE MOST beautiful house cake I have EVER seen!!! Includingg EVERY house cake I've seen by all the famous decorators! Yours blows theirs out of the water!!

AMAZING!!!!!

that's fantastic!! great job!

Wow, wow, and did I say wow! That is one awesome cake. So clean looking and proportionate. Great job

Thank you guys! I did work really hard on this cake and I enjoyed the end result!

I had no idea this post was about J.Low's house!! You were so criptic! I have to say, everyone there on Saturday really felt special to have that cake made for us. We are so used to oversized sheet cakes. This was truely special. How long did it take? And how much fondant??? It really was perfect.

That is AMAZING!!!

Have you though about entering the nat'l gingerbread house competition? I know it's in NC, I believe Asheville, and it's in Nov, I think. You would probably win, with all that detail!!!
