Do not add whipped cream swirl or banana slice on top until just before serving or the bananas will turn brown. You can rub a little lemon juice on banana slices to maintain their color, but this will change the flavor a bit.
You will have a couple spare graham crackers after assembling the icebox cake. These can be crushed by placing them in a plastic baggy and rolling over them with a rolling pin.
*Whipped cream or Cool Whip for the swirled garnish is not included in the recipe quantities.*
Store, covered with plastic wrap or an air-tight lid, in the refrigerator for 2-3 days. The bananas will not thaw well if frozen, so this is not a good one to store in the freezer.
