Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Graham cracker crumbs
Melted butter (unsalted)
Heavy cream, cold
Powdered sugar
Vanilla extract
Sweetened condensed milk
Key lime juice
Lime zest

Directions

Prepare the crust layer. Mix graham cracker crumbs with melted butter until the mixture is like wet sand. Press a layer of this into the bottom of your trifle dish (or glass containers).
Whip the cream. Using a chilled bowl and beaters, whip the heavy cream with powdered sugar and vanilla until stiff peaks form.
Make the lime filling. In a separate bowl, whisk together sweetened condensed milk, key lime juice, and lime zest until smooth.
Fold cream into filling. Gently fold about half of the whipped cream into the lime mixture to lighten it, using a spatula and sweeping motions.
Layer the trifle. Over the crust layer, add a layer of the key lime filling, then another graham cracker crust layer, then more filling, and top with remaining whipped cream.
Chill. Press plastic wrap directly onto the surface, then refrigerate for at least 2 hours (or up to overnight) so the layers set and meld.
Serve. Garnish before serving with extra graham cracker crumbs, lime zest, fresh berries, or mint sprigs if desired.

Servings and timing

Yield: About 8 servings
Prep time: ~15 minutes
Chilling time: 2 hours (or longer)
Total time: ~2 hours 15 minutes

Variations

Use digestive biscuits or vanilla wafers in place of graham crackers
Substitute bottled lime juice if key limes aren’t available
Make individual servings in jars or dessert glasses
Add layers of fruit like raspberries, blueberries, or sliced strawberries
Drizzle a bit of lime curd or passionfruit purée between layers
Add a splash of coconut rum to the cream for a tropical twist

Storage/Reheating

Refrigerator: Store covered for 2–3 days. The graham crackers will soften over time, so best eaten within that window.
Make‑ahead: Assemble up to 24 hours ahead. If desired, delay the top graham cracker layer until just before serving to maintain more crunch.
Freezing: Not recommended — freezing changes texture of whipped cream and softens the crust too much.

FAQs

Can I use regular lime juice instead of key lime juice?

Yes — regular limes work in a pinch. The flavor will be a bit more tart and less floral, but still delicious.

How long does this trifle last in the fridge?

It stays best for 2 to 3 days. After that, the crust will get soggy and the textures start to degrade.

Can I freeze it?

I don’t recommend freezing. The whipped cream can become grainy and the crust turns mushy when thawed.

Why did my whipped cream deflate?

Possible reasons: the bowl or cream wasn’t cold enough, overwhipping, or traces of grease in the bowl. Chill everything before whipping.

Can I make individual servings instead of one big trifle?

Absolutely! Use dessert glasses or mason jars and layer the same components.

When should I garnish before serving?

Do your garnishes — slices of lime, berries, extra crumbs — right before serving so they stay fresh.

Will the crust stay crunchy?

It will soften a bit over time but will retain some texture, especially if you delay the top crust until serving.

Can I omit or reduce sugar?

You can reduce the powdered sugar slightly, but it may affect sweetness balance. Omit only if comfortable with a more tart dessert.

What’s the best way to press the crust layer?

Use the bottom of a measuring cup or flat tool to press crumbs firmly and evenly so they hold together when sliced.

Can I add other flavors?

Yes — you can fold in a bit of coconut, mix in berries, or add a splash of flavored syrup (e.g., passionfruit, mango) for variation.

This Key Lime Pie Trifle is a show-stopping, no-fuss dessert that balances tangy lime with creamy sweetness and crunchy layers.
