Our June averaged about 100 degrees per day and about 95% humidity. I was terrifed of buttercream melting but I have a plan for delivery and delivered over 45 minutes away with no problem.
all of my completed cakes go in a box and I refrigerate overnight, even tiered cakes. I keep the box closed and put it straight from the fridge into a car that has the a/c running full blast and has been for at least 15 minutes to keep the car cool. I have an SUV and it sits in the back and the windows are tinted. It stays in the box unti I get it inside the venue. It goes from the box to the table. Even with our superhot and humid summer, I didn't have any melting. Most of the time, I use Sugarshack's buttercream but this worked even for a vanilla rum buttercream that is all butter. I was afraid that it was going to melt inside the venue because it was so hot in there but the bride said it held up great, no melting.
