Mixed Berry Cream Cheese Filling Be The First To Review By Teena_Marie recipe I made this for a cake I took to work. Everyone loved the filling so much that I thought I would share it with you all to try. Please remember that a cake with this has to be refridgerated. Mixed Berry Cream Cheese Filling Ingredients 8oz Philidelphia whipped Mixed Berry Cream cheese1 tsp vanilla1 cup confectioners sugar (Might need a bit more to stiff it up some) Instructions Mix all of the ingredients together and refridgerate until ready to use. I used this recipe to fill an 8 in square cake and still had a bit left over. Hope you like it.
