Hi  I’ve been asked to make a city transit bus cake for a retirement party  it needs to feed 50 people.  I’m wondering what size cake pans to use.  Should I use a 12 x 18 pan and cut it in half (lengthwise) and stack 4-5 layers?  Will that be enough cake?  Should I do an 11 x 15 pan?  I don’t know!  I’d love any recommendations please.

The 11x15 pan cut & "stacked" as you said should give you 56 slices 1x2x4.  (Cut the finished cake in 1/2 lengthwise, then cut 1" slices)  Or use the 12x18 --  make 2 12x18 cakes putting the 2nd one on it's own cake board & take them apart to serve each cut into 1x2x4 slices resulting in 72 servings.    So do you want extra  cake or just enough.   Just be ure to charge for all which ever way you go.   

Thanks kakeladi.  I always overestimate what i need and make too much
