a food processor add both packages and process until cookies resemble coarse crumbs. Pour 1 ½ cups of crumbs into medium mixing bowl, add melted butter and mix together until it starts to stick together. Press into the bottom of pie pan. Set in the fridge until ready to use.
a medium mixing bowl, add powder sugar and vanilla, set aside. Then in a small sauce pan combine first 3 ingredients and heat over medium. Stir constantly, about 3-4 minutes or until butter melts. Remove from heat, and pour into powdered sugar and vanilla, stir (using a whisk is best) until smooth.
it cool for a few minutes, 5-8 minutes. Using a spoon, drizzle large amounts of frosting over the cheesecake. I used all but 1/4 and then saved the rest to dip animal crackers in, but you totally could have used all the frosting.
a small mixing bowl or large glass measuring cup, melt chocolate in microwave for 1 minute, stir until completely melted, you may need to stick it back in the microwave for another 30 seconds. Set aside and cool to room temp, or cool to the touch.
cream cheese, butter, sugar, chocolate, and vanilla extract in large bowl until smooth. Now stir in Cool Whip until they are well combined; spread over prepared crust. Now top with 2 cups of miniature marshmallows and 1 1/2 cups of pecans. Then set in the fridge to chill until filling is slightly firm. Meanwhile make frosting. Add frosting to the top of cheesecake, over the marshmallows and pecans, I like to add a few extra marshmallows and pecans on top of the frosting too. Now put back in the fridge and chill for another hour.
Slice and garnish each piece with some crushed Nilla Wafers and sliced bananas. Evenly spread 1 1/2 cups of this mixture into the prepare pie crust (this is the 1st layer). Stir together until combined and add to the pie crust (as the 2nd layer)
