How long will this filling stay good. I am making a grooms cake for Saturday and need to know how long wil the filling will stay fresh in the cake with out the cookies getting nasty or soggy? Does it need to / can it be refrigerated or frozen? I I want to make the filling and fill the cake tommorow. Any advice would be greatly appreciated.

anyone?

For me, I find that it's best to add the cookies to the buttercream just before putting it in the cake. When I've combined earlier, I find the cookies become a soggy mess and when you spread it on your cake you just get a grey colored icing. I prefer the white icing/chunk-of-cookie look. To help with this, I keep a bag of regular buttercream handy and even add a little here and there to fill any spaces after spreading my cookies and cream buttercream. Also, I make my buttercream a little softer than usual since it seems the cookies absorb the moisture anyway. Once I have the cake filled, I think it's ok to sit as normal. Good Luck!

Thank you so much!
