This no-bake raspberry mousse cake is a quick and easy dessert that requires no baking. The crust is made with crushed graham crackers and butter, and the raspberry mousse is made with fresh raspberries, cream cheese, and whipped cream. The cake is then chilled until set, making it a perfect dessert for hot summer days. The raspberry mousse is light and creamy, with a tangy raspberry flavor that pairs perfectly with the sweet graham cracker crust.
