Preheat your oven to 350 degrees. Grease 24-cup mini-muffin tin.
In a medium-size bowl add vanilla wafer cookie crumbs, sugar, and melted butter. Mix until all ingredients are combined.
Using a spoon add your crumbs to each muffin space, making sure that you are pressing firmly and creating a pie shape.
Press down in the middle to create a deep space for your filling. Bake for about 10 minutes or until the edges are golden brown.
Allow your mini pie crusts to cool off completely before adding the filling.
In another bowl, whisk the instant banana cream pudding mix, vanilla, and cold milk until thickened. Refrigerate for 5 minutes.
Add 1/2 a cup of the whipped topping/cool whip and fold into the pudding mix. This will create a nice and fluffy pudding recipe.
Add your filling and remaining whipped topping into 2 separate plastic baggies. Cut the tip-off or use a star shape tip. This will make it really easy to fill in your pies.
Squeeze out a bit of the filling into one of your pie crusts, then squeeze some of the whipped topping on top. Decorate with a banana slice, and/or mini vanilla wafer cookie.
Use a knife to loosen from pan and they should pop right out.
