I'm going to be making a two tier cake for my father-in-law's 75th birthday. He requested that I make the Betty Crocker "Cherry Chip" flavour cake. (I was going to make a scratch cake, but he wants a mix instead )

I rented two Wilton rectangular pans...one is 9 x 13 x 2 and I know that it uses one box of mix. The other is 12 x 18 x 2. How many mixes will that use??? Do you think two boxes will be enough for the 12 x 18 pan?

Thanks in advance.

I use 3 in the 12x18.

Heck, I use 3 in a 11X15, so I'd use at least 3 in the 12X18.

I would think it would depend on if you are going to do anything with your mix. If I make the wasc, I use two batches of that recipe for my pan.

No, 2 is not enough. I usually use 3 1/2 mixes in the 11x15

I find you need about 1 1/2 cake mixes for the 9x13 to get a full cake. The 12 x18 should take 3 mixes.

Ikoenig07 Do you REALLY use 3 1/2 mixes for an 11x15?? wow!

Good thing I bought 5 boxes of cake mix "just in case."

I'm glad I asked...I would have ended up with a pretty flat cake had I gone my way.

A million Thanks to all.

I think a lot depends on WHERE you live....I'm up 5300 feet in the mountains and if put 3 mixes in my 2" pan I would be cleaning the overflow off the oven floor! 2 does it for me and 3 in the 3" deep pans for the 12x18. One in the little 9x13 fills it up nicely.

Wow! I live at 21 feet and 3 mixes would overflow my pan too! I only fill the pans 1/2 full, how high do you all fill?

I suggest doubling the WASC recipe (using the cherry chip cake mixes). I would mix a package of cherry Kool-Aid with the water that is required (for added flavor) OR 2 2/3 cups cherry soda and maybe 1 tsp almond extract and 3 tsp vanilla extract. i use one WASC recipe for the 12 x 18 and there will be more than enough to fill the 9 x 13. Fill the 9 x 13 first and put all the rest in the 12 x 18.
