I have not bought her book yet because I would like to know if I could use this recipe for 12x18 sheet cake if I double or triple it. Has anyone made and successful?  

Thanks.

I haven't done a 12x18... but I have done a 2" deep 12x12... It worked out fine...

I used bake even strips and upside down flower nails... five of them I think...

I also use it all the time in a 9x13 pan... full 2" deep...  bake even strips only... bakes up beautifully every time...

AAtKT, Thanks for your reply:) I will try with flower nails. Have you ever freeze it? 

I have had no need to ever put it in the freezer... 

but I do know it tastes better a day or two after I bake it... 

Also check out this thread... it is also about the cake:

I have never made a 12 by 18 - (it doesn't fit in my oven)  but I have made an 11 by 15 many times.  Doubling the SF from scratch recipe fills the 9 by 15 pan perfectly.  I would triple the recipe for a 12 by 18 and you might have a little left over for a smaller cake or cupcakes.  I have frozen this many times and it freezes beautifully.  It is a wonderful recipe, and I tried many.  

I want to make this for somebody's wedding and it is good to know that taste get better next day or so.

You helped me a lot. Thank you so much.

yortma,

It sounds like you love this recipe too.

I am going to buy the book!

So excited!!! thank you:)

Hi, I just ordered the book.

Is this real paper book? Is it going to be mailed out to my house?because after I ordered it , it says "it is ready to download" 

Thanks.

No... It is a download... You should get an email or something of the sort telling you how to download it... I don't recall since its been a while...

AAtKT,

I see.. I thought it is a book but that is ok.

I will check e-mail then when it is ready I will download it.

Thanks again.
