I came up with this key lime pie trifle one summer afternoon when I was craving something refreshing and bright but didn’t feel like turning on the oven. I had a few limes, some leftover graham crackers, and a tub of whipped topping and it hit me why not layer all the best parts of key lime pie into one no-bake dessert? So I did, and the first spoonful was everything I hoped for and more: tangy, creamy, cool, and perfectly sweet.

Now this trifle is a regular star at BBQs and potlucks and any time I need a quick dessert that still makes people say “wow.” It’s super easy to assemble, completely no-fuss, and those layers of lime mousse and crunchy graham cracker crumble never fail to impress. If you love citrus desserts or just need a simple showstopper, this one’s for you.

Ingredients

Here’s what I use for this recipe. You can always make substitutions if you prefer!
Key lime juice – Adds bright and tangy flavor that defines this dessert
Sweetened condensed milk – Sweetens and thickens the creamy filling
Cream cheese – Provides richness and structure for the mousse layer
Whipped topping – Keeps the texture light and fluffy
Graham crackers – Crushed for the classic pie crust crunch
Lime zest – Boosts citrus flavor and adds freshness
Lime slices – A beautiful and simple garnish on top

Tools You’ll Need

Hand mixer – I use this to blend the mousse until smooth and creamy
Mixing bowls – Great for preparing the filling and organizing ingredients
Rubber spatula – Helps fold in the whipped topping gently
Trifle dish or glass bowl – Shows off the layers beautifully
Citrus zester – Adds that final touch of fresh lime zest

Instructions

Step 1:

I begin by softening the cream cheese at room temperature so it blends easily and doesn’t clump.

Step 2:

In a mixing bowl, I beat the cream cheese until smooth, then I add the sweetened condensed milk and key lime juice and mix until everything is completely combined.

Step 3:

Next, I gently fold in half of the whipped topping with a spatula to make the lime mousse light and airy.

Step 4:

I crush the graham crackers into small crumbles – not too fine, because I like some texture between the layers.

Step 5:

Now it’s time to layer! I start with a scoop of the lime mousse, then sprinkle some graham cracker crumbs, followed by a dollop of whipped topping. I repeat this until I fill the trifle bowl.

Step 6:

To finish, I top the final layer with extra whipped topping, more graham cracker crumbles, and thin slices of fresh lime.

Step 7:

I chill the whole trifle in the fridge for at least 2 hours before serving so the flavors can come together.

Tips

If you want to make this even easier, I recommend using store-bought lime curd in the layers for extra richness. I also like to zest a little extra lime on top right before serving for a fresh citrus pop. And if you’re serving a crowd, use mini cups or jars for individual trifles they’re just as pretty and even more fun to eat!

Ways to Serve

I love bringing this to summer cookouts or holiday brunches – it’s a hit every time

Serve in mini parfait glasses for individual desserts at parties

It also works great as a make-ahead dessert for Easter, Mother’s Day, or baby showers
