Yes, you can definitely decorate a cake with freeze-dried raspberries! They make a great topping for cakes as they add a pop of color and texture. To keep the raspberries from getting too soft, it's best to add them to the cake just before serving or serving them in a separate bowl for guests to sprinkle on their own slices. If you want to add freeze-dried raspberries as decoration to the sides of the cake, try pressing them gently onto the frosted surface of the cake before storing it in the refrigerator. Just note that the raspberries may soften slightly over time and lose some of their crunchiness.
