It’s my own birthday month, my partner’s birthday month, and the birthday month for about 25 of our friends. While it packs the same festive punch as a 9-inch cake, a 6-inch layer cake just feels more casual than its full-size counterpart. Here’s the only problem with 6-inch layer cakes: There aren’t many recipes written to accommodate a 6-inch cake pan. But if you’re working with a layer cake recipe from the Before Times (or any recipe for an 8- or 9-inch cake), converting it to a 6-inch cake is an easy fix. So you need a 6-inch cake ready in the next two hours and you don’t have time for cake math?
