hi everyone
i jus got asked for a quote by a potential customer on an 11x15 cake
i have never done an 11x15 cake[dont even remember seeing one!]
but i was jus wondering if 2 9x13 cakes side by side would equal one 11x15?
i did check on old threads and saw that a double layer of that would serve 60 and single about 30 so that does give me a starting point..
id love any help u could give[i know i sound reallly stupid asking this but i read somewhere that a 9x13 was a quarter sheet cake and that 11x15 was half so i figured 1/4 plus 1/4 equals half?]

If you were to put two 9x13s together then that would be either a 9x26 or an 13x18......if I understand you question correctly. You can buy an 11x15 from Michaels or even Walmart. Check out the link below.

9x13 is a quarter sheet

and a 12x18 is considered a half sheet.

2-9x13's side by side will be close to the size of a half sheet/12x18 in size and servings.

If I remember correctly a 9x13 will give you 15 servings. A 11x15 will serve 35 and a 12x18 serves 54. So if you did 2 9x13's it will give you a total of 30 servings which is close to the servings of the 11x15 size, just a little short.

According to a chart I have (I believe it's Indydebi's):
9x13= 24
11x15=35
12x18=54

These are 2x2 pieces, so 2 9x13s are closer to a half sheet(12x1. HTH!
