What do you mean my friend? Ha ha you know i have had a crazy week I need more simple questions! ;)
Do you mean instead of a cake as in a whole cake or instead of cupcake treats etc.
I can’t really see there a problem with a cake in the park depending on the servings and detail.
When I do my kids cakes in the park I put them in an esky. (Chiller box) I either use 4:1 ganache or 100% shortening buttercream.
I also find cupcakes easier and less fuss to transport in one of those plastic carriers and I place ice packs (ice bricks) underneath it until happy birthday song time.
Anyway I clearly need sleep as I am starting to waffle but I hope that triggers some more discussion…
