Ingredients

1 ½ cups graham cracker crumbs
¼ cup sugar
1/3 cup unsalted butter, melted
2 (8-ounce) packages cream cheese, softened
1 (14-ounce) can sweetened condensed milk
½ cup fresh lime juice (about 4-5 limes)
1 tablespoon lime zest
1 ½ cups heavy whipping cream
¼ cup powdered sugar

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Start by preparing the crust. In a medium bowl, combine the graham cracker crumbs, sugar, and melted butter. Mix until everything is well combined and the crumbs are evenly coated with butter.
Press the crumb mixture into the bottom of a 9-inch pie dish, making sure to evenly cover the bottom and slightly up the sides. Use the back of a spoon to press the crumbs down firmly. Refrigerate the crust for about 15 minutes to set.
In a separate bowl, beat the cream cheese until smooth and creamy using a hand mixer or stand mixer.
Gradually add the sweetened condensed milk, lime juice, and lime zest, continuing to mix until everything is well combined and smooth.
In another bowl, beat the heavy cream and powdered sugar together until stiff peaks form.
Gently fold the whipped cream into the lime filling mixture until well combined, being careful not to deflate the whipped cream.
Pour the lime filling into the prepared graham cracker crust and smooth the top with a spatula.
Refrigerate the pie for at least 4 hours, or overnight, until the filling is fully set.
Before serving, garnish with additional lime zest or whipped cream if desired.

Variations

Graham Cracker Crust Alternatives: If you’re not a fan of graham crackers, you can easily substitute with crushed digestive biscuits or even Oreo cookies for a chocolate twist.
Key Lime Pie with Coconut: Add some toasted shredded coconut to the crust for an extra layer of flavor. You could also sprinkle some on top for a beautiful presentation.
Lemon Version: Swap out the limes for fresh lemons to create a lemon pie variation. It’s just as tangy and delicious!
Whipped Topping: If you prefer a lighter topping, use whipped topping instead of making homemade whipped cream.

Storage/Reheating

This No Bake Key Lime Pie should be stored in the refrigerator. Cover it tightly with plastic wrap or aluminum foil to prevent the pie from absorbing any odors in the fridge. It will keep well for up to 4 days.

Since this pie is served chilled, there’s no need to reheat it. Just take it out of the fridge a few minutes before serving to let it soften slightly for the best texture.

FAQs

How long does No Bake Key Lime Pie need to set in the fridge?

The pie needs to set in the refrigerator for at least 4 hours, but for the best results, I recommend leaving it overnight so the filling fully firms up.

Can I use bottled lime juice for this recipe?

Fresh lime juice is best for this recipe, as it gives the pie a bright, fresh flavor. However, if you don’t have fresh limes, bottled lime juice can be used in a pinch, but the flavor may not be quite as vibrant.

Can I make this pie ahead of time?

Yes! This No Bake Key Lime Pie is perfect for making ahead. It needs to chill for a few hours anyway, so making it the night before or several hours before serving works beautifully.

Can I freeze this No Bake Key Lime Pie?

While this pie is best when served fresh, you can freeze it for up to 1 month. Just be sure to wrap it well in plastic wrap and aluminum foil before freezing. When ready to serve, thaw in the fridge for several hours or overnight.

Can I use a store-bought crust?

Absolutely! If you’re short on time, using a store-bought graham cracker crust is an easy alternative. Just be sure to follow the same steps for preparing the filling.

This No Bake Key Lime Pie is the ultimate treat for anyone who loves a tangy and refreshing dessert with minimal effort.
