I need a filling (i'm making a crouquembouch with choux pastries for my wedding cake because i'm tired of doing regular cakes, so i'm going offbeat

but the thing is my wedding is going to be outside...in nebraska....the end of june. Thats like 90+ degree and with humidity on top of it. I want to fill the Choux with something that is semi cheap to make, taste well the Choux (i've never made them before) and will hold up in humidity.

Any one have any ideas?! thanks!

well, good luck! usually theyd be filled with cream, but that wont work for you. you could fill with ice cream, but again wont work.
im not sure that a good in the heat recipe like indydebis bc would really go with the pastry either, at least not as a total filling.
ganache is good on the outside, but a whole ball on the inside, im not convinced either, but a truffle filling might work? although not sure how it would go with the heat!
good luck! i love these things!

I was going to suggest Indydebi's buttercream as well. It stands up in the heat REALLY well and tastes delicious!
