Rainbow layered sheet cake

post #1 of 33
Thread Starter 
I have been asked to make a 6 layered rainbow sheet cake! They want it to feed 30-40 people so I was thinking 11x15 or 12x17. I was wondering what would be the best way to make the different colored layers without having a rediculousely thick cake? How much mix I would need?

Not really up to speed on the rainbow cakes but a 4 inch high 9 by 13 serves 50 so that size should be more than enough for the 30-40 guests.

A rainbow cake is when there are 6 layers and each layer is a different color of the rainbow then stacked in order red,orange, yellow, green, blue, purple. This cake is for a 2nd birthday party.

I know the concept but can't help with the amount of batter, etc for a rainbow cake.  They would have to be as thin as possible because when you add the 6 layers plus 7 layers of icing it will be really tall.

Doing a sheet cake, I'd be scared to make it too thin. Handling those cakes without them cracking is going to be a nightmare. I hate doing sheets even when they're 2 inches tall - I'm so nervous about breakage.

 

For 30-40 people could you steer them towards a 8 or 9" round? It would be easier to assemble and fit their servings much better. A sheet (even a 9x13) that's six layers is going to be a ton of cake! If you do the sheet, make sure you charge them for the actual servings - according to Wilton a 2-layer 9x13 serves 50. You'll be doing a 6-layer so even if you thin out the layers and filling, it'll be at least double the servings.

That is what I am afraid of too! They are insistent on a sheet, I usually do round for this style of cake. I tried explaining that is a lot of cake, I don't think they understand but who am I to argue if they want to pay for it. According to the Wilton web page it takes about 11 cups of batter for for an 11x15 2 in. Cake, Am I reading that right?

Then make them what they want but make sure you figure out the actual servings correctly and charge them appropriately.  Not only for the actual servings but  possibly additional for the extra mixing, baking, clean up required to make 6 separate cakes, 6 filling layers plus your usual icing and decorating.  11 by 15 is 74 servings even if you don't consider any extra servings for a higher cake.

Exactly - make whatever they want, just charge appropriately. If you give them your smallest sheet cake and tell them it serves x and your cost is $y/serving (including an up charge for the extra layers!!!)* they might change their mind. And if not, you'll take their money :)

 

*The more I think about this, the more I think I'd double my usual per serving charge. I usually do 3 layers of cake and 2 of filling, so a rainbow would be double the amount of cake. And then I'd tack on 20-30% for the sheer annoyance of 6 different colors of batter, having to bake the layers separately, the inevitable cracking and rebaking of 1 or 2 layers, etc.

 

May I ask what you quoted them for # of servings and total price?

Yes, there will definitely be extra charges on this one. According to Wilton an 11x15 3 inch cake is 60 1.5x2 inch servings. If I can get each layer about 3/4 of an inch it would only be 4.5 inches high plus frosting.

I quoted them $1.50 per serving for 60 servings because of the size of cake that they want and a total $175 because they want not only the layers of the cake to be rainbow but the entire top of the cake to be frosted in a rainbow and I will have to pipe it all by hand.


Do you mind me asking how much you would of quoted? Just out of curiosity.

5 layers of filling will add on another 1.25 inches if each filling is a quarter inch thick.  Plus your outside icing.  It seems like it will be at least 6 inches high. I think you should consider using the wedding size serving chart so you get some compensation for the extra height.  The extra height will  probably put you over the wedding serving volume anyway.

I have never made a wedding cake, I am fairly new to this...what is the difference in serving sizes?
post #13 of 33

My normal buttercream frosting, plain run of the mill cakes are $3/serving. I would have charged at least $6/serving for this cake, assuming the extra layers are about double the servings. Then probably rounded up to ~$7.50 accounting for the PITA factor and the extra piping on top. And for an 11x15, I would assume 74 servings (from WIlton). So a total of $450-$550 (range dependant on how much I liked this person and how much I know I would loathe making this cake). That's why I'm shocked they agreed to so much extra cake. Clearly, it should cost much more! I don't care if they eat it or throw it out, if I have to make it, they have to pay for it.

 

At $175, I cannot see how you are not losing money. Have you added up the cost of your ingredients and how much time this will take you? Those people are getting a steal. You are quoting less servings (60 is low even for a normal 2 layer cake!). And $1.50/serving is ridiculously inexpensive. I don't know your market, but around here $3/serving is on the low-end.

 

The cake you have described will serve about 125-150 people depending on the final height. You are basically charging slightly more than $1/serving. I don't know you, but I will assume you are worth much more than that :)

Is it possible to make your rainbow cake marble style? make enough batter to fit in one pan and separate the batter 6 ways and color them the colors of the rainbow. like this cake I made. it was a 9 inch round though :)

This cake was made using my white white cake recipe which normally makes three 9 inch round layers.  I baked the layers in 8 inch square pans using 12 ounces of batter per pan.  Because I only have two pans in that size I had to bake three times.  With the minimal amount of filling (they wanted more cake than filling and would have been happy with a smear of jam between layers) it was still 7.5 inches tall with the fondant.  I don't know what I would have charged for it.  It was a gift in exchange for the loan of a complete set of baby furniture and toys when my daughter came for Christmas with the littlest one.

If you're going to do a 9x13 with a similar sized recipe it could turn out about right as far as height goes, but I'd turn out my layers on one of those pebble surface cutting mats.  That way you can slide the layers on without breaking them, because they're going to be quite thin.  hth
