Classic No-Bake Key Lime Pie With Graham Cracker Crust
Bright, creamy, and impossibly easy — this classic no‑bake Key lime pie is pure sunshine in a slice.
Ingredients:
- 1 1/2 cups graham cracker crumbs (about 10–12 full crackers)
- 6 tablespoons unsalted butter, melted
- 1/4 cup granulated sugar
- 14 ounces sweetened condensed milk (1 can)
- 1/2 cup fresh Key lime juice (or fresh regular lime juice)
- 1 tablespoon fresh lime zest
- 1 cup heavy whipping cream, cold

How to Make:
- Combine graham cracker crumbs, melted butter, and 1/4 cup sugar in a bowl until mixture is evenly moistened.
- Press the crumb mixture firmly into the bottom and up the sides of a 9-inch pie pan to form the crust. Chill in the fridge while you make the filling.
- In a medium bowl, whisk together the sweetened condensed milk, lime juice, and lime zest until smooth and slightly thickened.
- In a separate chilled bowl, whip the heavy cream (and powdered sugar, if using) until soft to medium peaks form.
- Gently fold about one-third of the whipped cream into the condensed milk mixture to lighten it, then fold in the remaining whipped cream until fully combined and airy.
- Pour the filling into the chilled crust, smoothing the top with a spatula.

Instant Pot Key Lime Custard
Zesty, silky key lime custard made quickly in your Instant Pot — tart, creamy, and totally irresistible.
Ingredients:
- 4 large egg yolks
- 1/2 cup granulated sugar
- 1/4 teaspoon fine sea salt
- 1/2 cup freshly squeezed key lime juice (about 8–10 key limes) or regular lime juice
- 1 tablespoon lime zest (optional, for extra brightness)
- 1 1/4 cups whole milk
- 1/2 cup heavy cream

- 1 tablespoon cornstarch (optional, for slightly thicker custard)
- Pinch of powdered sugar or extra lime zest, for garnish (optional)

- Stir in the key lime juice and lime zest, then gradually whisk in the remaining milk, heavy cream, and vanilla until fully combined.
- Strain the mixture through a fine-mesh sieve into a heatproof container that fits inside your Instant Pot (a 2-cup or 3-cup glass jar or small metal bowl works well) to remove any bits of cooked egg or zest.
- Add the cubed butter to the strained mixture and cover the container tightly with foil to prevent condensation from dripping in.
- Pour 1 cup of water into the Instant Pot and place the trivet inside. Set the covered custard container on the trivet.
- Seal the Instant Pot and cook on High Pressure for 8 minutes.
- When the cook time ends, allow a 10-minute natural pressure release, then carefully quick-release any remaining pressure.
- Open the lid, remove the container, and whisk the custard briskly until smooth and glossy; if there are small lumps, re-strain.
- Taste and adjust sweetness or lime brightness if needed; chill the custard in the fridge for at least 2 hours to set and deepen flavor.
- Serve chilled, topped with a dusting of powdered sugar, extra lime zest, or a dollop of whipped cream if you like.
