This lemon raspberry mousse cake is a refreshing dessert that combines the tanginess of lemon with the tartness of fresh raspberries. The cake is made with a lemon sponge cake, layered with a creamy raspberry mousse, and topped with fresh raspberries. The mousse is made with fresh raspberries, whipped cream, and gelatin, giving it a light and airy texture. The cake is then chilled until set, making it a perfect dessert for a hot summer day.
