I just realized I never clarified Gladys question. Chickpeas in a box? No it is canned chickpeas where you use the liquid in the can.
Rachel-Cakes, I have used this icing on cupcakes that were piped 2 days ahead of a baby shower. They were fine, but it was mid April, and the weather was cool. I just realized I gave you the wrong link for the icing…Duh!! This one uses icing sugar, so much more stable.

Are you planning to use this icing alone on a cake? Once the icing has set, and the cake is in a cool room, it should be fine. And I’m assuming the venue would have AC. You could always make a test batch of icing. Pipe on some vegan cupcakes, or very small cake. Let sit for 48 hours, and see the results. Hope this helps.
