We have another cream filling that we love that is quick and easy. This "mousse" or chocolate cream filling is made from combining chocolate instant pudding and heavy cream. We used this Easy Chocolate Mousse recipe for our Chocolate Mousse Cake. It is delicious! We've also used various flavors of this easy filling in our Banana Pudding Cake, Orange Dreamsicle Cake, Easy Boston Cream Pie, and Chocolate Caramel Cake just to name a few!
