This low-fat chocolate raspberry truffle cake is perfect for those who want to indulge in a delicious dessert without all the calories. The cake is made with a combination of applesauce and Greek yogurt, and the raspberry filling is made with fresh raspberries and low-fat cream cheese. To make the cake, mix together the dry ingredients and then add in the wet ingredients. Bake the cake in two layers and let it cool. While the cake is cooling, mix fresh raspberries and low-fat 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 low-fat milk together and pouring it over the top of the cake. Let the ganache set before serving. This cake is low in fat and calories, but still tastes just as delicious as a traditional chocolate raspberry truffle cake.
