Making Piggy Pie Dessert is a straightforward yet enjoyable process. Follow these steps for a delicious outcome:

1. Prepare the Crust: In a mixing bowl, combine graham cracker crumbs and melted butter. Press the mixture firmly into the bottom of a 9-inch pie dish to form a crust.
2. Bake (Optional): For a firmer crust, you can bake it at 350°F (175°C) for 10 minutes. Allow it to cool completely.
3. Make the Chocolate Pudding: In another bowl, whisk together chocolate pudding mix and cold milk until it thickens. This should take around 2 minutes.
4. Combine Ingredients: In a separate bowl, mix the whipped topping and sweetened condensed milk until smooth. Add the vanilla extract and stir.
5. Layer the Pudding and Cream Mixture: Pour half of the chocolate pudding over the cooled crust, smoothing it out. Follow with half of the whipped topping mixture, spreading evenly.
6. Add Optional Ingredients: If you desire, sprinkle mini marshmallows and chopped nuts over the layers for added textures and flavors.
7. Repeat Layers: Add the remaining chocolate pudding, followed by the rest of the whipped topping mixture. Create a smooth top layer.
8. Chill the Dessert: Cover the pie with plastic wrap, and refrigerate for 2-3 hours to set. This chilling time helps meld the flavors beautifully.
9. Decorate: Before serving, add chocolate shavings or sprinkles on top for an extra touch of sweetness.
10. Slice and Serve: Cut into generous slices, and enjoy!
