a client is requesting whip cream in their cake but i never use whip cream because it has to be kept refrigerated at all times. the cake i'm making cant be refrigerated after i cover it with fondant therefore i cant use whip cream. i'm a new cake decorator... what can you suggest that i use instead that has somewhat of a similar taste?

can you get Pastry Pride, Frostin' Pride or Bettercream. They don't need refrigeration.

1st of all.......yes, you can frig a cake covered w/fondant
The products mentioned are good if you have access to them.

I forgot to mention that I have covered and refrigerated and even froze cakes covered in fondant. Not Wilton fondant though. The ones I use are Pettinice(sp) Choco-Pan and Satin Ice. I put them in a cardboard box, not a skimpy cake box, and then cover the box with plastic wrap, tin foil and more plastic.

I just read a post from Collette Peters saying she puts fondant covered cakes in the fridge all the time, she covers it w/ plastic wrap first.

I always refrigerate my fondant cakes after I am finished decorating them. ALWAYS!! I pull them out a couple of hours before I deliver them, but I have never run into problems.
