What Is Swiss Roll Filling Made Of?
Swiss roll filling is usually made of a sweet and creamy mixture such as whipped cream, jam, buttercream or frosting. The filling is spread evenly over the flat surface of the sponge cake before it is rolled up, creating a spiral of cake and filling that is both visually appealing and delicious. Some variations of Swiss roll may also include additional flavorings or ingredients in the filling such as chocolate, nuts, or fruit.
