Triple Layer Banana Creme Pie Bars

I got this recipe on the tried and trues blog. There is a link on my blog. I made it the other night and took it to my parents house. They all loved it. Some people had thirds. I love the fact that it is so easy and not to bananaish (is that a word?)

1 1/2 c. crushed Nila wafers
1/2 c. chopped pecans
1/3 c. butter, melted
3 bananas, sliced
3 c. cold milk
2 pkg. (4 oz) vanilla instant pudding/pie filling
2 1/2 c. thawed cool whip

Preheat oven to 325*. Mix wafer crumbs, nuts, butter in a 9x13 dish. Press firmly onto dish. Bake 8 mins. Cool 10 mins. Top crust with sliced bananas. Pour milk into large bowl. Add dry pudding mixes. Beat with wire whisk, for 2 mins or until well blended. Spoon 2 cups of the pudding over banana layer.Gently stir 1 c of cool whip into the remaining pudding. Spoon over pudding. Top with remaining 1 1/2 c. whipped topping. Refridgerate for 2 hours. Store leftovers in fridge.
