Ingredients You’ll Need
The magic of this dessert lies in its layers. Each one contributes to the final flavor and texture. Let’s break it down:
1. The Crust
- 1 cup all-purpose flour – Base structure of the crust.
- ½ cup unsalted butter (melted) – Holds the crust together and adds richness.
- ½ cup chopped nuts (pecans, walnuts, or pistachios) – Adds crunch.
- Pinch of salt – Balances sweetness.
👉 Substitutions:
- For a gluten-free option, use almond flour or gluten-free cookie crumbs.
- For a sweeter base, swap the flour crust with crushed Oreos, vanilla wafers, or graham crackers mixed with butter.
2. Cream Cheese Layer
- 8 oz cream cheese, softened – Smooth, tangy richness.
- 1 cup powdered sugar – Sweetens the layer.
- 1 cup whipped topping (Cool Whip or homemade whipped cream) – Makes it light and fluffy.
👉 Tip: Use full-fat cream cheese for the richest flavor, but you can substitute light cream cheese or even Greek yogurt for a lighter version.
3. Pistachio Pudding Layer
- 2 packages (3.4 oz each) instant pistachio pudding mix – The star of the show.
- 2 ¾ cups cold milk – Thickens the pudding.
👉 Always use instant pudding mix. Cook-and-serve pudding will not set properly in this dessert.
4. Topping
- 2 cups whipped topping – A creamy final layer.
- ¼ cup chopped pistachios or mixed nuts – Crunchy garnish.
- Optional: maraschino cherries, shaved chocolate, or crushed pineapple – For color and fun flavor accents.
Ingredient Swaps for Healthier Versions
- Use sugar-free pudding mix and light whipped topping.
- Replace butter with coconut oil for a dairy-free crust.
- Sweeten with natural alternatives like monk fruit or stevia.
- Swap cream cheese with a blend of Greek yogurt and honey for a tangy twist.
Step-by-Step Instructions
This dessert may look elegant, but it’s surprisingly easy to prepare. Here’s a breakdown of each step with helpful tips.
Step 1: Make the Crust
- In a bowl, combine 1 cup flour, ½ cup melted butter, ½ cup chopped nuts, and a pinch of salt.
- Press firmly into the bottom of a greased 9×13-inch baking dish.
- Chill for 15 minutes, or bake at 350°F for 15 minutes until lightly golden.
- Allow to cool completely before adding the next layer.
👉 Pro Tip: If baking, don’t overbake. A slightly underdone crust will keep it soft and easier to cut later.
Step 2: Prepare the Cream Cheese Layer
- Beat 8 oz softened cream cheese and 1 cup powdered sugar until smooth.
- Gently fold in 1 cup whipped topping.
- Spread evenly over the cooled crust.
👉 Pro Tip: Spread carefully so you don’t break the crust. A silicone spatula works best.
Step 3: Make the Pistachio Pudding Layer
- In a large bowl, whisk together 2 pudding mixes with 2 ¾ cups cold milk.
- Beat for about 2 minutes until thickened.
- Spread evenly over the cream cheese layer.
- Let sit for 5 minutes to begin setting.
👉 Pro Tip: Work quickly—instant pudding thickens fast!
Step 4: Add the Final Layer
- Spread 2 cups whipped topping across the pudding layer.
- Sprinkle with chopped pistachios.
- Optional: Add maraschino cherries for a vintage look.
Step 5: Chill and Serve
- Refrigerate for at least 2 hours, or overnight for best results.
- Slice into squares with a sharp knife.
- Serve cold and enjoy the creamy, nutty layers.
👉 Pro Tip: For cleaner slices, dip the knife in hot water and wipe between cuts.

One of the best things about pistachio pudding dessert is its versatility. Here are some fun variations:
