This may seem like a silly question but I am new to decorating but normally use basic recipes. I have a customer that has ordered Lemon cake with lemon filling. Most of the filling recipes on here have whipped cream in the recipe. I am making a cake shaped like an artists palette, which will be covered in fondant. I'm unsure of what to do because the fondant cant be refrigerated but if it has whipping cream in the filling then it will need to be right? Please help. Thank you.
