In a large mixing bowl, combine the pistachio pudding mix and cold milk.

Use a whisk to blend them together for about 2 minutes until the mixture thickens and becomes smooth.

Allow the pudding to set for 5 minutes to fully thicken up.

Carefully fold in the whipped topping until fully incorporated.

This step will make the pudding extra creamy and give it a light, fluffy texture.

Gently fold in the halved grapes to distribute them evenly throughout the pudding.

Add the chopped pistachios for that perfect nutty crunch. This combination of sweet grapes and crunchy pistachios will balance the creaminess of the pudding perfectly.

Optional: Add a drizzle of honey or maple syrup if you like a touch of extra sweetness.

Cover the bowl and place it in the refrigerator for at least 30 minutes. This gives the pudding time to set and the flavors to meld together.

Before serving, stir the pudding gently, and feel free to add a bit more whipped topping on top.

To serve, scoop portions into bowls or dessert cups.

For a fancy presentation, top with extra grapes, crushed pistachios, or a little extra whipped topping.

Enjoy the creamy, nutty goodness of this delightful pistachio pudding with grapes!
