I am doing my first outdoor wedding cake labor day weekend. Any suggestions on a tasty icing i can use safely that wont slide off my cake that hot weekend in St. Louis other than the typical butter/shortening buttercream?

Others on here have suggested ganache under fondant for me. I will be trying it for an outdoor wedding this Saturday. Wish me luck. I will post how well it holds up.

I always use ganache under my fondant, especially in the heat.

i cant use fondant. the bride says NO FONDANT!! i can only use some kind of buttercream and fondant accents. this is where my dilema is

A crisco based bc should hold up fine. If it has to be bc, that is the only option.
Or else ganache can look amazing as the final icing!
Or, marzipan and royal icing, although I don't know how it does in heat.

Be sure to have someone sign the care instructions - cool shady room (ac) as long as possible, and no direct sunlight.

Indydebbi's buttercream would hold up!!

I live in Florida and I use wilton and a lot of my partys are out doors you can use milk but I use water

I was a total skeptic about using the high ratio shortening frostings when I first came here to this message board. My whole life I made frosting with only butter - never frosting.

I took a risk and tried the Sugar Shack buttercream frosting, and haven't looked back. It is deliscious, and holds up well in the heat. Give it a try before you need the final product. You should be pleasantly surprised.

I use Indydebi's recipe and it holds up very well to heat and humidity.
