I remember the first time I tried key lime pie in the Florida Keys; I was hooked. This no-bake version captures that same zesty punch without the fuss. It's so easy, even my cat could make it (if he had thumbs).
So grab your whisk and let's get started. Your taste buds will thank you!
Why You'll Love This Recipe
About the Ingredients
1 1/2 cups (150g) graham cracker crumbs
From about 12 full graham crackers. Use gluten-free crumbs if needed, or substitute with crushed shortbread cookies for a sweeter crust.
6 tablespoons (85g) unsalted butter, melted
Salted butter works too; just omit the added salt in the crust. Vegan butter also works well.
1/4 cup (50g) granulated sugar
For the crust. You can reduce or omit if using sweetened crumbs.
1 (14 ounce/396g) can sweetened condensed milk
The backbone of the filling. For a dairy-free version, use coconut condensed milk.
1/2 cup (120ml) key lime juice (about 20 key limes)
Fresh is best. If you can't find key limes, use regular limes with a bit more zest. Bottled key lime juice is a decent backup.
1 tablespoon key lime zest (about 4 key limes)
Adds extra aroma. Regular lime zest works as a substitute.
8 ounces (226g) cream cheese, softened
Full-fat gives the creamiest texture. Neufchâtel (low-fat) works but is slightly less rich.
1/2 cup (120ml) heavy whipping cream
For the whipped topping. You can also use 1 cup of thawed frozen whipped topping instead.
2 tablespoons powdered sugar
For sweetening the whipped cream. Adjust to taste.
1/2 teaspoon vanilla extract
Enhances the whipped cream flavor. Omit if you prefer pure lime.
Tips & Tricks
- Use fresh key lime juice if possible; bottled has a different flavor profile. If using regular limes, add a bit more zest to get that floral aroma.
- Soften the cream cheese fully to avoid lumps. Let it sit at room temperature for 30 minutes before mixing.
- Chill the pie for at least 4 hours, but overnight is best. It sets firmly and slices cleanly.
Pro Tips
Step-by-Step Instructions
1. Make the Crust
In a medium bowl, combine graham cracker crumbs, sugar, and melted butter. Press firmly into a 9-inch pie plate, covering the bottom and up the sides. Place in the fridge while you prepare the filling.
2. Beat Cream Cheese
In a large bowl, beat the softened cream cheese with an electric mixer until smooth and fluffy, about 1 minute. Scrape down the sides.
3. Add Condensed Milk
Gradually beat in the sweetened condensed milk until fully incorporated. The mixture should be smooth and creamy.
4. Mix Lime Juice
Pour in the key lime juice and zest, then mix on low just until combined. The mixture will thicken slightly. Set aside.
5. Whip the Cream
In a separate cold bowl, whip the heavy cream, powdered sugar, and vanilla until stiff peaks form. Be careful not to over-whip.
6. Fold Together
Gently fold the whipped cream into the lime mixture using a spatula, until no white streaks remain. This creates a light, airy filling.
7. Fill the Crust
Pour the filling into the chilled crust and smooth the top with a spatula. Tap the pie plate gently to remove air bubbles.
8. Chill and Serve
Refrigerate for at least 4 hours, or until set. Before serving, top with additional whipped cream and lime zest if desired. Slice and enjoy!
Delicious Variations

Frequently Asked Questions
Q: Can I use regular limes instead of key limes?
Yes, you can use regular limes, but the flavor will be less floral and more tart. To mimic key lime, add a bit more zest. Key limes are smaller and more acidic with a distinctive aroma.
Q: Why is my no-bake key lime pie runny?
A runny pie usually means it wasn't chilled long enough or the filling wasn't thick enough. Ensure you chill for at least 4 hours, and if using cream cheese, make sure it's fully softened. Also, don't overmix the lime juice; mix just until combined.
Q: Can I make this pie without cream cheese?
Yes, you can omit the cream cheese and increase the condensed milk slightly, but the texture will be denser. For a lighter version, use Greek yogurt in place of cream cheese, but that changes the taste.
Q: How do I know when the pie is set?
The pie should be firm to the touch and not jiggle when gently shaken. You can also insert a knife near the edge; it should come out mostly clean.
Q: Can I use bottled key lime juice?
Yes, bottled key lime juice is a convenient substitute. Just make sure it's 100% juice and not a sweetened limeade. The flavor will be slightly less bright but still delicious.
