Southern Banana Pudding

So this might not look like much but it's kinda the best thing ever. Growing up in the south Banana Pudding was a staple at family get togethers, BBQ restaurants, cook outs, you name it.  I personally love my mom's recipe...well because she's my mom and it's the best.

2 (3oz) packages instants vanilla pudding
3 cups milk
8 oz sour cream
1 (12oz) container cool whip
1 (13oz) box nilla wafers
6 large bananas (sliced)

Combine the vanilla pudding, milk and sour cream, let it thicken a bit. Fold in the cool whip. In the bottom of a 9x13 pan layer the nilla wafers, half of the bananas then half of the pudding mixture. Do one more layer with the remaining nilla wafers, banana slices and pudding. Cover and refrigerate overnight.
