It is perfect for summer parties, family gatherings, potlucks, birthdays, Easter, or any occasion that needs a light and refreshing dessert.
**Prep Time:** 30 minutes
**Chill Time:** 4 hours
**Total Time:** 4 hours 30 minutes
**Servings:** 10–12
**Ingredients**
**For the Graham Cracker Layer**
* 3 cups graham cracker crumbs
* 6 tablespoons unsalted butter, melted
* 3 tablespoons granulated sugar
* ¼ teaspoon salt
**For the Key Lime Filling**
* 16 ounces cream cheese, softened
* 2 cans sweetened condensed milk, 14 ounces each
* ¾ cup freshly squeezed key lime juice or regular lime juice
* 2 tablespoons finely grated lime zest
* 1 teaspoon vanilla extract
* 1 cup cold heavy whipping cream
**For the Whipped Cream**
* 2 cups cold heavy whipping cream
* ½ cup powdered sugar
* 1 teaspoon vanilla extract
**For Garnishing**
* Fresh lime slices
* Extra lime zest
* Graham cracker crumbs
* Crushed graham crackers, optional
**Step-by-Step Instructions**
1. Add the graham cracker crumbs, melted butter, granulated sugar, and salt to a medium bowl. Stir until the crumbs are evenly coated and have the texture of wet sand. Set aside while preparing the filling.
2. Place the softened cream cheese in a large mixing bowl. Beat with an electric mixer for 2–3 minutes until smooth, creamy, and completely free of lumps.
3. Gradually add the sweetened condensed milk while continuing to mix. Beat until the cream cheese and condensed milk are fully combined.
4. Pour in the key lime juice, lime zest, and vanilla extract. Mix for another 1–2 minutes. The lime juice will naturally help thicken the mixture.
5. In a separate chilled bowl, beat 1 cup of cold heavy whipping cream until stiff peaks form. Gently fold the whipped cream into the key lime mixture with a spatula. Fold slowly to keep the filling light and airy.
6. To prepare the whipped cream layer, place 2 cups of cold heavy whipping cream in a clean bowl. Add the powdered sugar and vanilla extract. Beat until the cream becomes thick and forms stiff peaks. Be careful not to overmix.
7. Sprinkle one-third of the graham cracker mixture evenly into the bottom of a large glass trifle bowl. Press it down very lightly with a spoon.
8. Spread one-third of the key lime filling over the graham cracker crumbs. Add a layer of whipped cream and smooth it gently.
9. Repeat the layers two more times, using the remaining graham cracker crumbs, key lime filling, and whipped cream. Finish with a generous whipped cream layer on top.
10. Decorate the trifle with fresh lime slices, lime zest, and extra graham cracker crumbs.
11. Cover the trifle and refrigerate it for at least 4 hours. Chilling overnight will produce an even firmer texture and richer lime flavor.
**Tips and Notes**
Use room-temperature cream cheese to prevent lumps in the key lime filling. Fresh lime juice gives the dessert the brightest flavor, but bottled key lime juice can be used when fresh key limes are unavailable. Keep the heavy cream cold until you are ready to whip it. Chilling the bowl and beaters for 10 minutes can also help the cream whip faster.
For neat, attractive layers, transfer the key lime filling and whipped cream to separate piping bags. Pipe each layer around the edge of the glass bowl before filling the center. You can also assemble the recipe in individual glasses or small mason jars for parties.
Do not press the graham cracker layers too firmly because the dessert should remain soft enough to scoop. Add the fresh lime slices shortly before serving so they stay bright and fresh.
**Frequently Asked Questions**
**Can I make this trifle ahead of time?**
Yes. It can be assembled up to 24 hours before serving. Keep it tightly covered in the refrigerator.
**Can I use regular limes?**
Yes. Regular Persian limes work perfectly, although key limes have a slightly more aromatic and floral flavor.
**How long can leftovers be stored?**
Store leftovers covered in the refrigerator for up to 3 days. The graham cracker layers will gradually become softer.
**Can I add cake to the layers?**
Yes. Cubes of vanilla pound cake or angel food cake can be added between the filling layers for a more traditional cake-style trifle.
