Filling: 1 large box of cooked banana cream pudding (NOT the INSTANT) (I used Vanilla pudding as I thought the Banana cream would make the whole cake TOO banana flavored QV)
Make pudding according to directions on the box and cool completely. Slice 3 additional firm ripe bananas. Split the layers in half, putting pudding & sliced bananas onto 2 layers, and the whipped cream on the others. Frost the whole cake with whip cream & sprinkle chopped walnuts on top. (Next time I'll use Cool Whip Lite and I put chopped pecans on top of the cake instead of walnuts. QV) This cake can be put together ahead of time (like several hours) but needs to be refrigerated until it is eaten. I used Dr Oetker Whipit in the whip cream, it's a terrific stablilizer.
