I make 1/2 sheet cakes for alot of different occasions and have used the chocolate butter cake recipe in the cake bible in the back for the 2 / 12 x 2 in pans (round). I was rereading some things and I was wondering if I should be adjusting the baking powder because of the size. I do wish Rose would tackle this question in her book because ALOT of us do those type of cakes and I would like to convert some of her recipes but frankly, I don’t always have the time (work a full time job besides my cake business) or want to waste ingredients (money) on something that may not turn out. I don’t want to have to always do practice cakes either. Round cakes are beautiful, but sheet cakes are practical for alot of different celebrations.

Thanks,
Colleen

i like your concerns.

What size is your pan?  I see Rose covers 13 x 9 in the Master Chart.

1/2 sheet size; 12 x 18. Graduation cake size and such. Making 2 / 9 x 13’s doesn’t always work and it’s one more pan to wash hahah

On the Master Chart, Rose covers 12x18 for yellow, white, and chocolate butter cake. I made 12x18 genoise using her chart on TCB. Also, I once download Michell’s Excel chart for Cake Bible. She covered 11 x15x2 size pan.

thank you, I have used those recipes by making the 12 x 2’s. I guess my wish was that more of her recipes were converted more easily to larger sizes. There is such a selection but so many are for 1 layer (which I know some can be doubled successfully). Not too many people make a single layer cake, especially those of us that bake for others.
so why do you dear Rose make recipes for such small cakes!?

Hi, Colleen!

I’ve doubled (and 2.5x’d or more) nearly every cake I’ve made (almost all butter/oil cakes) with complete success, so I think you can be safe there.  I’ve made smaller sizes—baked them in bread pans, mini bread pans, 8” pans and 7” pans with complete success, as well.  I haven’t ventured larger, which I know is your primary concern, and I know it’s sketchier territory, but I did want to throw in about the doubling, etc.
