Hi! Has anyone ever used Wilton Cookie Icing? I am wondering if it dries hard enough to stack cookies or wrap them in cello bags. Would RI be the best icing to use? I'm kind of new to the cookie game.

I'd use royal just because it is easier to use and easier to pipe/flood with.

You are welcome. The few times I have used the premade stuff it was a struggle to squeeze it out of the container for me. I'd much rather make something that I have control over the consistency of.
