Pudding and Filling

1 box Pistachio instant pudding mix Use instant pudding for quickest results.
2 cups Cold milk Use regular dairy milk for best texture.
1 container Whipped topping (or whipped cream) Store-bought is stable; homemade works best if consumed sooner.
1 package Vanilla wafers or graham crackers Choose based on preference; vanilla wafers create a retro feel.
1/2 cup Chopped pistachios Optional for topping; can substitute with almonds or pecans.
1 cup Mini marshmallows Optional, adds an ambrosia-like texture.

Preparation

In a large bowl, whisk the pistachio instant pudding mix with cold milk for about 2 minutes until it thickens. Let it sit for 3 to 5 minutes until it firms up more.
Gently fold in the whipped topping until no streaks remain. If using, fold in mini marshmallows.

Layering

Spread a thin layer of the pistachio mixture at the bottom of a 9x13 inch dish.
Place vanilla wafers in a single layer on top of the pistachio mixture.
Continue layering by adding more pistachio filling, followed by more cookies. Repeat until ingredients are used up, ending with a layer of pistachio filling on top.
Sprinkle chopped pistachios on top for extra texture and garnish.

Chilling and Serving

Cover and refrigerate for at least 6 hours, preferably overnight to allow the flavors to meld and the cake to set.
When ready to serve, cut into squares with a sharp knife. Wipe the knife between cuts for cleaner edges.

This dessert can last in the fridge for 2-3 days but is best consumed fresh. Freezing is possible, resulting in a more ice cream-like texture.
