Ingredients You’ll Need
-
Pudding Layer:
- 1 package (3.4 oz) instant vanilla pudding mix
- 1 1/2 cups cold milk
- 1/2 cup sweetened condensed milk
- 1/2 cup key lime juice (fresh or bottled)
- 1 teaspoon lime zest
Whipped Cream Layer:
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
Trifle Assembly:
- 1 prepared pound cake or angel food cake, cut into 1-inch cubes
- 1 1/2 cups crushed graham crackers
- Extra lime zest or slices for garnish
How to Make Key Lime Pie Trifle
Step 1: Mix the Pudding Base
In a large mixing bowl, combine the instant vanilla pudding mix and the cold milk. Whisk vigorously for about 2 minutes, until the mixture just starts to thicken. This creamy base sets the stage for all the other wonderful flavors to join in shortly!
Step 2: Blend in the Key Lime Magic
Add the sweetened condensed milk, key lime juice, and lime zest to your pudding base. Whisk everything together until completely smooth and well blended. You’ll notice the mixture becomes even silkier, and you can already smell that refreshing lime aroma—it’s hard not to sneak a taste at this stage!
Step 3: Whip the Cream
In a separate bowl, pour the heavy whipping cream and add the powdered sugar. Using an electric mixer (or a little elbow grease and a whisk, if you’re feeling ambitious), whip the cream until stiff peaks form. This rich, fluffy topping is truly the crowning glory of your Key Lime Pie Trifle.
Step 4: Lighten the Lime Filling
Gently fold half of your freshly whipped cream into the key lime filling. This lightens the mixture beautifully, creating a soft, mousse-like texture that layers perfectly with cake and graham crackers in your trifle.
Step 5: Layer the Trifle
Now comes the fun visual part! Start by arranging half of the cake cubes in the bottom of a large trifle dish or several individual cups. Spoon on half of the tangy key lime filling, then sprinkle generously with crushed graham crackers. Repeat the layers once more, letting everything pile up in tempting stripes of color and flavor.
Step 6: Top and Garnish
Finish your masterpiece with the remaining whipped cream, spreading it in gorgeous fluffy peaks. To make it look every bit as tempting as it tastes, add extra lime zest or thin lime slices as a garnish. All that’s left to do is pop it in the fridge for at least 2 hours, letting the flavors mingle and the trifle chill to perfection.
How to Serve Key Lime Pie Trifle

Garnishes
Your Key Lime Pie Trifle loves a little flourish! Swirl on clouds of whipped cream, then top with a sprinkle of fresh lime zest or a playful twist of lime slice. A few extra graham cracker crumbs dusted on top also add crunch and visual appeal—consider each layer a canvas for your creativity.
Side Dishes
Because this trifle is bright and creamy, it pairs well with simple accompaniments that won’t overshadow its citrusy zing. Fresh berries (like raspberries or blueberries) bring a refreshing snap, or serve it after grilled seafood or barbecue for a sweet, palate-cleansing finish.
Creative Ways to Present
Key Lime Pie Trifle looks spectacular in a classic glass trifle bowl, but don’t hesitate to get whimsical! Ladle individual portions into mason jars, cocktail glasses, or even teacups for a fun twist at your next party. Mini trifle cups are great for buffets or picnics, and kids especially love having their own little dessert jar.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, simply cover your trifle tightly with plastic wrap or transfer individual servings to airtight containers. Store in the refrigerator for up to 2 days. After that, the cake may start to soften a bit too much, but the flavors will still be wonderful.
Freezing
While most trifles aren’t ideal candidates for the freezer (the fresh whipped cream and cake can change texture), you can freeze the key lime filling itself in an airtight container for up to a month. Thaw in the fridge overnight and assemble the layers fresh for the best results.
Reheating
No need to reheat this Key Lime Pie Trifle—it’s designed to be served cold straight from the fridge! In fact, it tastes best thoroughly chilled, which brings out that signature tang and makes the cream extra luscious.
FAQs
Can I use regular limes instead of key limes?
Absolutely! While key limes have a slightly floral flavor and a touch more tartness, regular Persian limes make a fantastic substitute if you can’t find key limes. Your Key Lime Pie Trifle will still be bright, zesty, and delicious.
Is it possible to make this ahead of time?
Yes! In fact, this dessert is ideal for making a day ahead—the flavors have time to blend and the trifle sets up beautifully in the refrigerator. Just add your garnishes right before serving for the best presentation.
Can I substitute the cake for something else?
You sure can. While pound cake or angel food cake are classic, try using ladyfingers for a lighter touch or cubed shortbread cookies for a richer, buttery version. The idea is to have a base that soaks up the limey cream while maintaining some structure.
What if I don’t have a trifle dish?
No problem! Layer everything in a large glass bowl, casserole dish, deep pie plate, or even in individual glasses or jars. The layers will look just as lovely and taste just as incredible.
Can I use store-bought whipped topping instead of making my own?
Store-bought whipped topping is a handy shortcut and works well in a pinch, but if you have time, freshly whipped cream truly makes the Key Lime Pie Trifle shine. The flavor and texture can’t be beaten!
Final Thoughts
This Key Lime Pie Trifle brings sunshine to any table, with its lively, citrusy cream and playful layers of cake and crunch.
