I left, left over wedding cake in the car last night in 70-80 degree weather.  brought it in this morning and put it in the freezer today.  will it be 'safe' to eat at this point ?

thanks

Only if it is cake and buttercream.  If it has any kind of custard filling or whipped cream, toss it.  Traditional buttercream is only powdered sugar, shortening and butter with a little milk or water.  I don't think it will taste good, though.  

Hi, i personally would chunk it. I,m sorry you forgot it. I think the heat will make everything taste different.

There are many things that you have not told us as have been mentioned.

What filling and icing was used.  Is it for a customer or your family:)

You might try the smell test......if it smells o.k. try a little piece to see how it tastes.

If for a customer I would NOT give it to them.

Toss it.  If it was 80 degrees outside it was way hotter in your car.  It is fine to leave buttercream at room temperature but 80 degrees is NOT room temp.  And any cream based items would need to be kept chilled at all times so even room temp overnight would not be okay.
