Pistachio Pudding Dessert Recipe

This pistachio pudding dessert is a no bake, four layer dessert made in a 9×13 dish: a shortbread and pistachio crust, a sweet cream cheese layer, instant pistachio pudding, and whipped topping with chopped pistachios. It takes about 20 minutes of hands-on work, then at least 4 hours in the fridge, and cuts into 12 squares.

The one thing to get right is the pudding. Two boxes get only 2½ cups of milk, far less than the box asks for, so the green layer sets thick and holds its shape when you slice. The oven never goes on, which is why I make it on hot days.

Four Layers in One 9×13 Dish

• Crust: 1½ cups crushed shortbread cookies (or vanilla wafers), ½ cup chopped roasted salted pistachios, 6 tablespoons melted unsalted butter
• Cream cheese layer: one 8 oz package cream cheese, 1 cup powdered sugar, 1 cup whipped topping
• Pudding layer: two 3.4 oz boxes instant pistachio pudding mix, 2½ cups cold milk
• Top: 2½ cups whipped topping and ½ cup chopped pistachios
• Shopping note: you need 3½ cups whipped topping in total, so one 8 oz tub falls a little short; buy a 12 oz tub
• Time: 20 minutes prep, 4 hours chilling minimum, overnight for the cleanest cuts
• Yield: 12 servings

Pressing the Shortbread Pistachio Crust

Crush the shortbread fine, like coarse sand with a few small bits left. Walkers or Lorna Doone both work. Chop the salted pistachios small enough to spread evenly, but not to powder; the salt is what keeps the sweet layers above from tasting flat.

Stir in the melted butter until every crumb is coated. Squeeze a handful: it should clump and hold. Tip it into the dish and press it down with the flat bottom of a measuring cup, gently at first to spread it, then with real weight. Chill it while you make the next layer. A cold, firm crust is what lets you spread the cream cheese without dragging crumbs up into it.

A Smooth Cream Cheese Layer With No Lumps

Leave the cream cheese out until it is fully soft; a finger should sink in with no push back. Beat it with the powdered sugar on its own until completely smooth, then fold in 1 cup of whipped topping by hand. Folding keeps the air in, so the layer stays light but still spreads like soft frosting.

Drop spoonfuls all over the cold crust and spread from the middle out with an offset spatula. This layer is the tang that balances the pudding. I once tried mascarpone here: milder and silkier, but it lost the slight sharpness I like, so I stick with regular cream cheese.

Setting the Pistachio Pudding Thick Enough to Slice

Whisk both boxes of pudding mix with 2½ cups cold milk for about 2 minutes, until it thickens. Then let it sit for 3 to 5 minutes. With the full 4 cups the box calls for, the pudding stays soft and slides into the cream cheese; with 2½ cups it sets like a thick custard you can cut.

Do not wait much longer than 5 minutes. Pudding keeps firming in the bowl, and once it is stiff it tears the soft layer underneath when you spread it. Use cold whole or 2% milk. Instant pudding needs cold milk to set, and skim gives a looser layer.

Whipped Topping, Toasted Pistachios and the Long Chill

Spread the remaining 2½ cups of whipped topping over the pudding in slow, light strokes so you do not pull up the green layer. Scatter the last ½ cup of chopped pistachios over the top. I toast mine in a dry pan for a few minutes, just until they smell nutty, then chop them. It makes the crunch warmer and deeper.

Now it needs the fridge: 4 hours at the very least, and overnight is better. The crust firms, the pudding sets fully, and the layers stop sliding when you cut.

Cool Whip or Real Whipped Cream on Top?

Cool Whip holds its shape for days, which is why the card uses it. To use real cream instead, whip about 1¾ cups cold heavy cream with 3 to 4 tablespoons powdered sugar to stiff peaks; that gives roughly the 3½ cups you need for both layers. It tastes fresher and less sweet, but plain whipped cream starts to weep after a day or two, so serve this version within 2 days.

Shortbread or Vanilla Wafers for the Crust?

Both are in the card, and both work. Shortbread holds up better in the fridge. It stays crisp longer and adds a buttery, dense base under the soft layers. Vanilla wafers give a lighter, sweeter bite that softens a little more by day two.

For a summer lunch, wafers are fine. For a dinner party or a holiday table, or anything you make the day before, I always use shortbread.

Soupy Pudding, Lumpy Cheese or a Crumbly Base

• The pudding layer never set: too much milk, warm milk, or cook and serve pudding instead of instant. Use exactly 2½ cups cold milk with instant mix and give it the full chill.
• Little white lumps in the cream cheese layer: the cream cheese was still cold. Beat it smooth with the sugar before any whipped topping goes in; folding cannot fix lumps afterwards.
• The pudding tore the cream cheese layer: it sat too long and got stiff. Spread it within about 5 minutes, dropping it in spoonfuls first.
• The crust falls apart on the plate: the crumbs were not pressed hard enough or the butter was short. Press firmly and chill the crust before layering.
• Messy, smeared slices: it needs more time in the fridge. Cut it cold, and wipe the knife with a hot damp towel between cuts.

Slicing, Storing and Making It Ahead

Serve it straight from the fridge. Made the night before, it cuts into neat squares with clear stripes of crust, white, green and white. It also travels well to potlucks in a covered glass dish, as long as it goes back in the cold soon after.

Cover tightly with plastic wrap so the topping does not pick up fridge smells, and keep it for 3 to 4 days. I do not freeze it. The pudding and topping hold a lot of moisture and turn watery and grainy when they thaw. To make it ahead, assemble it the evening before and add the chopped pistachios just before serving so they stay crunchy.

Pistachio Pudding Dessert Questions

Is this the same as pistachio lush?

Yes, it is the same family of layered pudding desserts. Many older potluck versions bake a crust of flour, butter and nuts first; this one stays no bake with a shortbread crumb crust.

Is it the same as Watergate salad?

No. Watergate salad, also called pistachio fluff, is pistachio pudding mix folded with whipped topping, pineapple and marshmallows and served by the spoonful. This dessert is layered on a crust and cut into squares.

Can I make the pistachio pudding from scratch?

You can, and the flavor is more nuanced, but homemade cooked pudding sets softer and less green than instant mix. For clean layers and that color, instant pudding works better here.

Can I use a different pan?

The amounts are made for a 9×13 dish. A smaller pan gives thicker layers that need the full overnight chill to set through.

More Recipes Using Pistachio Pudding Mix

If you have a spare box of instant pistachio pudding, it turns a plain cake mix into a moist, green pistachio pudding cake, and it gives soft, chewy pistachio pudding cookies their color. For a pie with the same creamy layers, try my pistachio cream pie, or go richer with a no bake pistachio cheesecake.

The same layered method works with other flavors too. My lemon lush dessert is a bright summer version, and pumpkin lush is the one I make in the fall. For pistachio with chocolate, these pistachio chocolate swirl cake squares are baked but just as easy to cut and share.
