In a large bowl, add the cold milk, vanilla bean paste and pudding mix. Whisk for 2 minutes until thickened. Next, fold in 8oz of cool whip. Reserve about 4oz for the top of the pudding.
In a trifle or large bowl (or casserole dish, small cups, whatever you have), arrange a layer of cookies at the bottom, followed by the pudding mixture. Then, add a few banana slices on top. Next, add another layer of cookies and continue layering until you have three layers, ending with the pudding mixture.
Next, add the reserved cool whip to the top layer. Use an offset spatula to spread evenly. Feel free to add more of the whip cream if you like (this recipe is all about preference).
Next, crush the remaining cookies and add them to the top of the banana pudding. I like a lot of cookies in my banana pudding; so, I typically have to open another box for the topping, but you can very well use the same box depending on cookie preference.
Cover the bowl and chill for at least two hours before serving. Enjoy!
