Key Lime Pie Lush

Key lime pie lush is a creamy, layered dessert that’s cool, tangy, and incredibly refreshing. I start with a buttery graham cracker crust, then layer it with a sweetened cream cheese base, a zesty key lime pudding layer, and a fluffy whipped topping. It’s light, luscious, and the perfect no-bake treat for summer—or anytime I want a dessert that tastes like sunshine.

Why You’ll Love This Recipe

I love how this dessert comes together without needing the oven. It’s bright, smooth, and bursting with key lime flavor, balanced by the richness of cream cheese and the crunch of a graham crust. Each layer complements the next, and the texture is just dreamy. It’s make-ahead friendly, perfect for parties, and always a crowd-pleaser.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the crust:

• Graham cracker crumbs

• Granulated sugar

• Melted butter

For the cream cheese layer:

• Cream cheese (softened)

• Powdered sugar

• Whipped topping or whipped cream

• Vanilla extract

For the key lime layer:

• Instant vanilla or cheesecake pudding mix

• Milk (cold)

• Key lime juice

• Lime zest (optional, for extra flavor)

Topping:

• Whipped topping

• Crushed graham crackers or lime zest (for garnish)

Directions

1. I mix the graham cracker crumbs, sugar, and melted butter until evenly combined, then press the mixture firmly into the bottom of a 9×13-inch dish. I chill it while I prepare the layers.

2. In a bowl, I beat the softened cream cheese with powdered sugar and vanilla until smooth, then fold in whipped topping until light and fluffy. I spread this over the chilled crust.

3. In another bowl, I whisk together the pudding mix, cold milk, and key lime juice until thick and creamy. I pour and smooth this over the cream cheese layer.

4. I top it all with a final layer of whipped topping.

5. I refrigerate the dessert for at least 4 hours (or overnight) to allow the layers to set and flavors to meld.

6. Just before serving, I sprinkle with extra crushed graham crackers or lime zest for garnish.

Servings and timing

This recipe makes about 12 to 16 servings. It takes around 20 minutes to prepare and needs at least 4 hours to chill, but I prefer to let it sit overnight for the best texture.

Variations

Sometimes I use golden Oreos or vanilla wafers instead of graham crackers for the crust. I’ve also made it with a coconut whipped topping for a tropical twist, or added a thin layer of key lime curd between the pudding and cream cheese layers for an extra punch. If I want individual portions, I layer everything into cups or jars.

Storage/Reheating

I keep leftovers covered in the fridge for up to 4 days. It holds its shape well and tastes even better on the second day. I don’t recommend freezing, as the texture of the cream and pudding layers can become grainy once thawed. No reheating is needed—it’s best served cold.

FAQs

Can I use bottled key lime juice?

Yes, bottled key lime juice works great and saves time. I just make sure it’s 100% juice for the best flavor.

What’s the difference between key lime and regular lime?

Key limes are smaller, more aromatic, and slightly sweeter and more tart than regular limes. Either can work in this recipe, but I love the classic flavor key lime gives.

Can I use homemade whipped cream?

Absolutely. I whip heavy cream with a bit of sugar until stiff peaks form and use it in place of store-bought whipped topping.

Can I make it ahead of time?

Yes, I often make this dessert a day in advance. It holds up beautifully and gives the layers time to firm up and blend together.

Why didn’t my layers set properly?

If the pudding didn’t thicken, it may be due to using too much liquid or not whisking long enough. I make sure to use instant pudding and cold milk, and I chill the dessert for several hours before slicing.

Conclusion

Key lime pie lush is a no-bake dream—tangy, creamy, and so easy to make. I love how the flavors and textures come together in this layered dessert, with just the right balance of sweet and tart. Whether for a cookout, a holiday, or just because, this refreshing treat always brings a little brightness to my table.
