In a bowl add the pudding mix and milk. Whisk for about 2 minutes and let stand for 5 minutes. It will thicken up.
While waiting crush the vanilla wafers, I like to use a blender or food processor for this. You want them crumbled but not too fine. Set aside.
Chop up bananas into about 1/4 inch thick slices.
The pudding should be set. Add the condensed milk & sour cream to the pudding mix. Whisk together with a whisk or you can use an electrical hand mixer until it's smooth with no lumps.
Start to fold in the whipped cream with a baking spatula. Gently do this to ensure maximum fluffiness. Don't over mix.
Start to layer the waffle cone bowls. Put a sprinkle of crushed wafer on the bottom, layer next with the pudding, a layer of crushed wafers and bananas, more pudding, more banana, pudding and top off with crushed wafers. Repeat these steps with all the bowls. Feel free to layer however you want.
The pudding is good to eat right away! Enjoy!
