In a large mixing bowl, whip the heavy whipping cream until it starts to thicken.
Add powdered sugar and vanilla extract. Continue whipping until stiff peaks form. Be careful not to over-whip.
Layering
In a rectangular or square dish, start with a layer of vanilla wafers at the bottom.
Add a layer of banana slices on top of the sponge cake.
Spoon a layer of whipped cream over the bananas, spreading it evenly.
Repeat
Repeat the layering process until you reach the top of the dish, finishing with a layer of whipped cream on top.
Chill
Cover the bread with plastic wrap and place in the refrigerator for at least 4 hours or overnight. This chilling time allows the flavors to meld, and the wafers to soften, creating a cake-like texture.
Serve
Once fully chilled, slice and serve the Banana Icebox Cake. The layers should have melded into a delicious, creamy delight with the sweetness of bananas and the crunch of vanilla wafers.
