Dream Whip: Using an electric mixer whip together both packets dry whipped topping mix with 1 1/4 cup cold half and half. Whip for 3 minutes or until firm peaks form.
To the bowl add both packages of instant pudding, 1 3/4 cups of cold half and half and 2 tsp pure vanilla extract.
Beat on medium speed for 2-3 minutes until thickened. Add cream cheese and whipping for 1-2 minutes until fully combined and fluffy.
Assemble: Place one cake round on a cake platter. Spread half of the filling over the bottom layer of cake then top with cubed bananas. Gently press the bananas into the filling.
Repeat cake layer, filling and cubed bananas. Top with the last cake layer.
Frost the tops and sides with whipped topping and garnish with vanilla wafers. Chill for at least 6 hours before cutting.
Store leftovers chilled.
Notes
Please note:
If you choose to use a cake mix for this cake, you'll only need half the filling.
To save time, the cake layers can be baked in advance, cooled then wrapped in plastic wrap and chilled until assembling.
