Hi - when I was a kid (more years ago than I care to admit), mom would make the "Favorite Coffee Cake" from the Betty Crocker cook book for the family, in a 9 x 13 pan.
I decided to bring one of those coffee cakes to her house as a surprise for us all this Thanksgiving, but when I pulled my cook book out to look at the recipe (it's on page 55 of my version, which is from 1975! It's not in my 1991 version), I see it calls for a 9" round or an 8" or 9" square pan.
Can I safely just double it for the 9x13 size? I really don't want to make it twice.
Thanks, Jane
