I Need to make a Cake for 100 People. I bake from stratch and this time around I want to go with Cake box mix. My question. How many boxes would I need and which brand will hold up more and can I do carving? Thanks for looking, response and your time.

hi Miasuzzette,
I think that the amounts for two layered tiers are as follows:

8 in - 1 box
10 in - 2 boxes
14 in - 6 or 7 boxes

Either Duncan Hines or Betty Crocker will work fine!

A cake mix makes appoximately 5 1/2 cups of batter. This is roughly a 9" pan - serving 32 people (according to wilton wedding chart). There is not a cake mix that can withstand carving (they are too moist and will crumble). You will need a doctored cake mix to withstand the carving. Check the link for recipe.

HTH!

I've used plan cake mixes to carve before. I guess it depends on exactly what you need to do with it.

Have you thought about using one of the extender recipes? They give you more batter than a standard cake mix alone.

I'd use this chart and base the servings off of which cake size you start with, rather than how many box mixes you need to get the 100 servings. From it you can see how many cups of batter you will need. Each brand and each flavor with in the brand make different amounts of batter.
