I have been ordered cake to feed 800

200 morning Monday
200 afternoon Monday

200 morning Tuesday
200 afternoon Tuesday

Next month

These are sheet cakes with simple decorations
How many 12X18 sheet cakes do I need?

I'm planning to use Italian Buttercream How many cups do I need?
How much should I charge??
I don't have access to big mixer, I have 2 7-qt mixers
and three convection ovens and my friend who works for a local grocery store bakery will help.
My main concern is making the buttercream, I have a garage fridge and a big kitchen fridge.
This is a cake my boss ordered from me to help me with an extra money

I'm scared! Help Please Should I do it

That size sheet cake serves 72 wedding- or 54 party-sized servings. If you go with 54, you will need 4 sheets each time. 16 sheets total. The Wilton book says a one-layer (3") half sheet needs about 8 cups of icing to decorate.

good luck!!

I am pretty new at selling my cakes, mostly they have been for family get toethers, my kids birthdays, etc., but in the last few weeks I have had several requests for sheet cakes from others. I checked prices at a few local bakeries for their sheet cakes (1/4, 1/2 and full) and then priced mine inbetween the lowest and highest. For all of yours, do they each have to be differnt or just the four each day? If you have to come up with sixteen completely different ideas, then I think the price should be a little higher.

Single layer 12x18, when cut in 2x2x2" squares, serves 54. Double layer serves 108. So two double-layers (4 of the 12x18's) will serve 216-ish.

thanks for all your answers,

I think 16 1/2-sheets will do the job

does anybody has an estimate of how many cups of buttercream I need?

Doen't have to e exact just an idea.

Thanks again for your help

With sixteen 1/2-sheets, I think you're way past measuring it in "cups"! icon_lol.gif

My rule of thumb is 2lbs of p.sugar for every 7 cake mixes (or the equivalent of).

I'd probably make up 12-15 lbs (measured by the lbs of p.sugar used, not necessarily the lbs of the end product) of icing...... to START.
