Classic Key Lime Pie, No-Bake and Easy
If you want a bright, cool dessert that feels special without much work, this key lime pie is a great choice. This no-bake version is easy to make ahead, which makes it handy for family gatherings, Easter tables, birthdays, or warm days when you do not want to turn on the oven.

One reason key lime pie works so well for small-batch cooking is that it uses simple pantry ingredients and takes very little active time. You can mix the crust, stir the filling, and let the fridge do the rest.
It also serves neatly in small slices, so it feels just right for 1 to 2 people. If you are cooking for a small group, you can double it with ease and keep the texture smooth and easy to serve.
Ingredients You’ll Need

- 1/2 cup graham cracker crumbs
- 1 tablespoon granulated sugar
- 2 tablespoons melted butter
- 1/2 cup sweetened condensed milk
- 3 tablespoons key lime juice, fresh or bottled
- 1 teaspoon lime zest, optional
- 1/4 teaspoon vanilla extract
- 1/3 cup heavy whipping cream
- 1 teaspoon powdered sugar
You can serve this creamy pie with a few fresh berries, or keep it plain for a simple finish.
Step-by-Step Recipe

- Make the crust. In a small bowl, mix the graham cracker crumbs, sugar, and melted butter until the crumbs look evenly moistened.
- Press the crust into 2 small dessert cups, a 6-inch pie dish, or 2 ramekins. Use the back of a spoon to make it firm and even.
- Mix the filling. In another bowl, stir together the sweetened condensed milk, key lime juice, lime zest if using, and vanilla extract until smooth.
- Spoon the filling over the crust. Smooth the top with a spoon or small spatula.
- Whip the topping. In a chilled bowl, beat the whipping cream and powdered sugar until soft peaks form.
- Top the pie with whipped cream. Add it right away, or chill the pie first and add the topping just before serving.
- Chill for at least 4 hours, or until set. Overnight is even better for a firmer slice.
