This easy chocolate raspberry truffle cake is perfect for those who want a delicious dessert without spending hours in the kitchen. The cake is made with a boxed chocolate cake mix, and the raspberry filling is made with raspberry jam and cream cheese. To make the cake, simply follow the instructions on the cake mix box and bake two layers of chocolate cake. While the cake is cooling, mix raspberry jam and cream cheese together to make the filling. Once the cake has cooled, spread the raspberry filling between the layers and refrigerate for at least an hour. Finally, make the chocolate ganache by melting chocolate and heavy cream together and pouring it over the top of the cake. Let the ganache set before serving. This cake is easy to make and tastes just as delicious as a homemade cake.
