Preheat oven to 350 degrees.
In a food processor, finely crush the Oreos.
Mix in the sweetened condensed milk until fully combined and it is sticky.
Spray the bottom of a 9x13 pan and press the Oreo cookie crust into the bottom of the pan.
Bake for 10 minutes or until it stiffens on the top.
Set aside and let cool after baking.
In a separate bowl, mix the cream cheese, powdered sugar. Lightly fold in 1 cup of the whipped cream, until fully combined.
In a different bowl, mix the two small packages of vanilla pudding mix and milk, until the pudding is set up. Then add 1 cup of the whipped topping and the pumpkin puree, until well combined.
Add the pumpkin spice, cinnamon, and nutmeg to the fluffy pumpkin mixture.
Once the Oreo crust has cooled, spread the cream cheese layer on top first.
Once the cream cheese layer has been spread, spread the pumpkin layer next.
Top the layers with the last cup of whipped topping.
Garnish with Oreo's, and story in fridge or freezer until ready to serve.
