Ingredients for Pistachio Pudding Icebox Cake

6.8 ounces instant pistachio pudding mix: This is where that wonderful pistachio flavor comes from! It also helps thicken the filling, so don’t skimp.
2 ¾ cups milk: I always use whole milk for the richest flavor, but 2% works just fine if that’s what you have on hand. Don’t use skim!
16 ounces whipped topping, thawed and divided: This gives the pistachio graham cracker dessert a light and airy texture. Make sure it’s fully thawed before you start.
14.4 ounce graham crackers (1 box): These form the “cake” layers and soften beautifully as it chills. I prefer the regular kind, but honey graham crackers would be yummy too!
Chopped pistachios (optional topping): These add a lovely crunch and enhance the pistachio flavor. Trust me, don’t skip them if you can! Just make sure they’re unsalted.

How to Make Pistachio Pudding Icebox Cake

Step 1: In a large bowl, whisk the pistachio pudding mix and milk together for about 2 minutes until smooth. You’ll see it start to thicken up slightly – that’s how you know it’s working.
Step 2: Gently fold in half of the thawed whipped topping until just combined. Be careful not to overmix! You want to keep that light and airy texture. Trust me on this one.
Step 3: Cover the bottom of a 9 x 13 inch baking dish with a single layer of whole graham crackers. You’ll probably need to break some to fit snugly, and that’s totally fine. I usually just eyeball it.
Step 4: Spread half of the pistachio pudding mixture evenly over the graham crackers, making sure to get into all those little nooks and crannies.
Step 5: Repeat with another layer of graham crackers, followed by the remaining pistachio pudding mixture. We’re building a masterpiece here!
Step 6: Top with a final layer of graham crackers and then spread the remaining whipped topping evenly over the top. This is where you can get creative with swirls and peaks if you’re feeling fancy.
Step 7: Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. This is the hardest part – waiting! But it’s so worth it to let those graham crackers soften and the flavors meld together. The longer this pistachio graham cracker dessert chills, the better the texture.
Step 8: Before serving this easy pistachio dessert, garnish with chopped pistachios if desired. Slice and serve cold. Enjoy every creamy, dreamy bite!
