I am making my brothers grooms cake for his wedding and I don't know what sizes of pans I should use. I am making it with two teirs- and it needs to serve between 50 - 70 people. Please give me any advice you have on what sizes of cakes to use. Thanks!
Wilton.com has pan sizes/serving sizes.
9" 7" gives you 49 servings,
10' 7" gives you 59 servings
12" 10" gives you 99 servings.
I would encourage you to look at the Wilton chart above and make sure it's the correct amount.
These are 'wedding cake slices', not 'sit down and eat a hunk of cake', slices.
I hope this helps,
I'd make a 10" x 6" for 50 servings... if they need more, you could add a third tier by using an 8" in between for 74 servings, or have a 9"x13" quarter sheet cake on the side for 75 total servings instead.
