The first time I made it, I did it by hand-- I try to make everything by hand, when I have the chance to.
It became a sticky mess, though. xD
I tried again, using a stand mixer, and even it seemed to have some trouble.
I think, what the issue was, was the recipe was too large. I feel like, if I halved the recipe itself, that I would have a much easier time-- but I wasn't thinking about that at the time.
