I am going to make a cake for a baby shower. I am making the gumpaste figures first. I want to make a carrot cake and a white or chocolate cake. What type of filing can go in a fondant cake? Do I have to only use buttercream thin coat under fondant?
I make a whipped cream mousse for 99 percent of all my cakes. The cake does require refrigeration before and after serving. I have left cake out for up to five hours with no problems using this filling. It is so good. I generally use one small box of instant vanilla pudding and one pint whipping cream. Whip until peaks form. I like to use white chocolate, cheesecake, chocolate fudge and banana cream puddings. I frost cakes as I normally would and then cover with fondant. I don't use a thin coat because most people don't like fondant. You can also frost your cake in ganache and then cover with fondant. This gives a nice sharp edge to your fondant cakes.
I've used all types of filling, all the fillings I use in non fondant cakes, it shouldn't make a difference as long as you dam your filling you should be ok. I use whole fruits, fruit purees, creams, curds, jams, all types never had a problem...
