Regarding the question on how long they would last above on the cake itself, imo the cookies did get a little soft sitting on the pudding topped cake after a few hours, but it still tasted great! if anything, the softening made it easier to cut through, and serve a bit of “moss” with every cake slice! =) thanks so much! wish i could share a picture w/you, Carrie! Maybe you can find it on my IG: kymmeeh? turned out so cute, and could not have done it without you! =D

They will be fine for a day or two. Treat them just as you would cookies! Sitting out uncovered, they will eventually dry out just as a cookie would. So if you need to make them last for awhile, keep them stored in an airtight container until you’re ready to use. A light covering of plastic wrap over the entire cake would help as well.
