I have been asked to do the kindergarten graduation cake for my children's school. They usually get 2 full slabs from our local grocery store which they say feed 60-70 each, so im looking to serve about 150 people. What size cake pans should I use to get enough cake. I was hoping to use my round or hexagon pans so I don't have to go out and rent any. TIA

Are you wanting to make a stacked cake? For party size pieces you would have to make the whole set. According to my book that would be around 110-120.

Yes I was thinking of making a stacked tiered. I have the round 6,10.14x3 and also the 4pc hexagon from wilton. I also have a 12x18 slab or a 14x14 square that I can use to make up for the extra servings. TIA

If you use your 14x14 and then make a 12x12 out of the 14x14 or your 12x18. On top you could at a hexagon pan or a round. That would be enough. or use a hexgon on the 2nd layer and a round on top. I bet the kids would like all the different shapes.

That actually sound great with all the different shapes. Thanks so much!
