To serve it fully frosted, then yes. Or, you can simply layer the ingredients in the pan and serve it that way. If you have a glass 9x5 pan, the presentation is gorgeous when you can see the layers through the side. With a steady hand, you can also assemble and serve the strawberry icebox cake on a cake platter! You’ll need to layer the ingredients in reverse, starting with the graham crackers. I recommend piping the whipped filling as well.
