No Bake Key Lime Pie
Tangy, creamy, and refreshingly sweet, this no bake Key lime pie is the perfect easy dessert for spring and summer.
There is no oven time, no fuss, and only a handful of ingredients between you and a slice that tastes like a tropical getaway in every bite.
If you have ever stood in a hot kitchen in July wishing dessert would just make itself, this recipe is for you.
I started making this pie for our family cookouts a few summers ago, and it has quietly become the thing everyone asks about before they even sit down.
My youngest calls it the green pie, my husband requests it for his birthday instead of cake, and I love that I can put it together in about 20 minutes in the morning and pull it out of the fridge after dinner.
It serves 8 slices and travels well to potlucks, which is more than I can say for most desserts I make.
The pie comes together in three simple parts. A buttery graham cracker crust goes into a 9 inch pie dish first and chills while you work on the filling.
Then a cream cheese and sweetened condensed milk base gets brightened with Key lime juice, lime zest, and vanilla extract. Finally, whipped topping is folded in gently so the filling stays light and airy instead of dense and heavy.
Prep takes about 20 minutes, and the pie needs at least 4 hours in the refrigerator, or overnight if you have the time. That long chill is what sets the filling and lets the lime flavor settle into something cool and creamy. Plan it for the night before a party and dessert is basically done before the day even starts.
A no bake pie is only as good as its chill. Give it the full 4 hours and the slices come out clean every single time.

Why This No Bake Key Lime Pie Works
Most no bake pies fail in one of two ways. Either the filling is too soft to slice, or the lime flavor disappears behind all that sugar. This recipe avoids both problems, and it does it without any specialty equipment.
The structure comes from cream cheese and sweetened condensed milk working together. The cream cheese gives body, the condensed milk gives sweetness and a silky texture, and the whipped topping lightens everything up so the filling never feels heavy. Meanwhile, a full half cup of Key lime juice keeps the flavor bright and unmistakably tart.
There is also the practical side. No oven means no heating up the house in August, no waiting on a baked custard to set, and no cracked top to worry about. You mix, you pour, you chill, and you serve. That is the whole story, and it is exactly why this pie earned a permanent spot in my summer rotation.
Ingredients for No Bake Key Lime Pie
Everything here is easy to find at a regular grocery store. If Key limes are not in season or you cannot find them, bottled Key lime juice works well and keeps the flavor consistent all year long.
For the crust
- 1 ½ cups graham cracker crumbs
- ¼ cup sugar
- 6 tbsp unsalted butter, melted
For the filling
- 8 oz cream cheese, softened
- 1 (14 oz) can sweetened condensed milk
- ½ cup Key lime juice
- 1 tsp lime zest
- 1 tsp vanilla extract
- 1 cup whipped topping, such as Cool Whip or homemade whipped cream
For the topping, optional
- Whipped cream
- Lime zest
- Thin lime slices
A quick note on the cream cheese. It really does need to be softened. Cold cream cheese leaves little lumps that never quite smooth out, and you will notice them in the finished pie.
Set it on the counter about an hour before you start, or soften it in short bursts in the microwave until it gives slightly when you press it.
How to Make No Bake Key Lime Pie Step by Step
Five steps, one bowl for the filling, and no oven. Here is the whole process from crust to garnish.
- Make the crust. Stir together the graham cracker crumbs, sugar, and melted butter until well mixed. Press the mixture into a 9 inch pie dish. Chill it while you prepare the filling.
- Prepare the filling. In a mixing bowl, beat the cream cheese until smooth and fluffy. Slowly mix in the sweetened condensed milk, then add the Key lime juice, lime zest, and vanilla extract. Mix until creamy.
- Fold in the whipped topping. Gently fold it into the filling to keep the mixture light and airy.
- Chill. Pour the filling into the crust and smooth the top. Cover and refrigerate for at least 4 hours, or overnight.
- Finish and serve. Top with whipped cream and garnish with lime zest or slices for a pretty finish. Slice and enjoy.

Tips for the Perfect No Bake Key Lime Pie
- For a more tropical flavor, add a splash of coconut extract or top the pie with toasted coconut flakes.
- For mini pies, use a muffin tin lined with cupcake wrappers for bite sized versions.
- Keep the mixer on low when the lime juice goes in so the filling does not splash up the sides of the bowl.
- Use a light hand when folding in the whipped topping. Overmixing deflates it and the filling loses that airy texture.
- Chill the crust while you beat the filling. It firms up just enough to hold its shape when the filling is poured in.
- Wipe your knife clean between slices and you will get neat, bakery style wedges instead of smeared edges.
Serving Suggestions
This pie is lovely on its own, but a few small touches make it feel like something you ordered at a restaurant.
- Serve it with a drizzle of raspberry or strawberry sauce on the side for a tart contrast against the creamy filling.
- Chill your plates before serving. On a hot day it makes the whole dessert feel extra refreshing.
- Swap the regular whipped cream for coconut whipped topping for a tropical flair.
- Add thin lime slices and a little extra zest right before the pie goes to the table so the garnish stays bright.
- Pair it with iced tea or a glass of cold sparkling water for a simple summer dessert table.
Storage and Make Ahead Notes
Leftovers keep well in the refrigerator for up to 4 days. Cover the pie tightly, or press a piece of plastic wrap gently against the surface of the filling if you want it to stay looking fresh.
If you would rather not eat the whole pie in a few days, freeze individual slices instead. Wrap each slice well, freeze it, and then move a single slice to the fridge when a quick dessert craving hits.
Because the pie needs at least 4 hours to set, it is a natural make ahead dessert. I usually build it the night before a cookout and garnish it right before serving, which means the busiest part of the day is already handled.
Frequently Asked Questions
What can I use instead of graham crackers for the crust?
For a no-bake key lime pie, you can substitute graham cracker crumbs with crushed vanilla wafers, shortbread cookies, or digestive biscuits. You can also use crushed nuts like pecans or almonds combined with melted butter. The canonical recipe uses 1½ cups graham cracker crumbs, ¼ cup sugar, and 6 tablespoons melted unsalted butter. Use the same proportions with your chosen substitute for a similar texture.
How should I store no-bake key lime pie?
Store leftover no-bake key lime pie in the refrigerator, covered, for up to four days. For longer storage, freeze individual slices wrapped tightly in plastic wrap and placed in a freezer-safe container for up to two months. Thaw overnight in the refrigerator before serving.
What is the difference between key lime pie and regular lime pie?
The main difference is the type of lime used. Key lime pie uses small, aromatic, and more acidic key limes from the Florida Keys, giving a distinctively tangy flavor. Regular lime pie typically uses Persian limes, which are larger, less acidic, and milder in taste. This no-bake recipe calls for ½ cup of key lime juice for its signature tartness.
Why didn’t my no-bake key lime pie set properly?
The most common reasons are using cream cheese that was not fully softened or folding in whipped topping that was too warm. Ensure the cream cheese is at room temperature and the whipped topping is cold. Also, the pie needs at least four hours of chilling time, but overnight is ideal for the filling to set completely.
