Instructions
To Make the Filling:
In a large bowl, whisk or beat with an electric mixer on medium speed the instant pistachio pudding mix and milk until smooth and thickened.
Fold in 1 cup of whipped topping until combined.
To Assemble the Dessert:
Place a layer of graham crackers on the bottom of a 9x13-inch dish. You’ll need about 6-7 full sheets of graham crackers per layer.
Spread half of the pistachio pudding filling evenly over the graham cracker layer. Add another layer of graham crackers, then spread the remaining pistachio filling on top.
Finish with one last layer of graham crackers.
Topping:
Top with the remaining whipped topping. Sprinkle with chopped pistachios.
Chill:
For minimum 4 hours, in the fridge, preferably overnight.
Serving:
Before serving, cut into squares of your desired size (about 12–15 pieces).
Notes
Make sure the whipped topping is fully thawed before using so it folds easily into the filling.
To slice squares, give the dessert plenty of time to chill in the fridge. This allows the filling to set properly and the graham crackers to soften.
For the best flavor, refrigerate overnight to let the flavors combine fully.
