A cool, creamy, and nostalgic no-bake dessert that tastes like summer camp but looks like a dinner party. Perfect for Labor Day cookouts, this icebox cake layers chocolate mousse, marshmallow fluff, and graham crackers for a crowd-pleasing treat without turning on the oven.
Chill overnight for best texture. Let chocolate cool to bathwater temperature before folding into cream to avoid deflating. Use full-fat cream and full-sheet graham crackers for best results. Clean knife between cuts for neat slices. Can be frozen for up to 2 months.
