I had a football helmet cake for a superbowl party all finished and in the refrigerator.

I was out all day and came home to find the cake out on the counter! It's been out of the refrigerator for longer than 5 hours. Is it still ok guys?? I'm so sad! I need it for tomorrow!

It was the cookies and cream filling recipe found here on CC, then covered in ganache and then covered in fondant. Please say it's ok to serve.

Was it this recipe:

(If not, please post a link to the recipe you did use, or nobody will be able to give a good answer, not knowing was was in the filling.)

If it was that recipe, and the buttercream you used as a base is stable at room temperature (most are), then I don't see why it would be a problem. I use regular American buttercream (all-butter) with broken up Oreos quite often, and see no reason why it can't stay out for 5 hours.

redpanda, unfortunately no I used this one:

that has heavy whipping cream. I know it needs to be refrigerated but I'm hoping that with the ganache and fondant coating and the cold weather that it may still be ok.

What would you do? I can't make another cake in time and it came out so nice
