Does anyone know how far in advance you can fill a cake with a heavy whipped cream filling? I whipped the cream with powdered sugar yuntil it was very stiff, Im just not sure that it will not start to seperate! I wont be serving the cake until Sunday! Any advice would be great! Thanks!

is it stabalized whipped topping or just regular? if it's just regular, I would wait as long as possible.

Thanks, Calejo! I was about to fill both cakes, yikes!! Maybe Ill go with a cream cheese filling instead!

I have tried different ways of stabilizing whipping cream and of all of them, I find using the Wilton recipe (from their stie) that you add piping gel to holds up the longest. But even using a stabilized whipped cream, I don't fill more than 24 hours ahead, but with the gel it will hold up and not separated on the iced cake, for 3-4 days. I didn't find using the Oetker Whip-it, made it hold up quite as long on the iced cake but still worked very well. Without a stabilizer, I would be using it to fill the same day.

That oreo and whipped cream filling is just amazing tasting and the oreos seem to act as a stabilizer. So the filling will stay for a few days.

I actually have done the oreo and whipped cream thing, its from The Whimsical Bakehouse book, it is so incredibly yummy!!!! I didnt have any oreos on hand or I would have used that recipe, thanks for all the advice!!
