They’re adorable, they’re delicious, and they’re dangerously easy to pop into your mouth. Perfect for parties, potlucks, or just treating yourself to a little burst of sunshine. One batch, endless smiles.
Instructions
Preheat and Prep
Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or generously grease each cup.
Make the Crust
In a medium bowl, combine the graham cracker crumbs, sugar, and salt. Pour in the melted butter and stir with a fork until all the crumbs are evenly moistened.
Press the Crust
Divide the crust mixture evenly among the 12 muffin cups (about 1 heaping tablespoon each). Use a small glass or a tart shaper to press the crumbs firmly into the bottom and up the sides of each cup. A firm, compact crust is essential.
Pre-Bake the Crusts
Bake for 8-10 minutes until fragrant and lightly golden. Set aside to cool slightly. Leave the oven on.
Make the Filling – Whisk the Base
In a medium bowl, whisk the egg yolks vigorously for about a minute until they’re thick and pale yellow. Pour in the sweetened condensed milk and whisk until completely smooth and well combined.
Add the Lime Juice
Slowly pour in the lime juice while whisking constantly. The mixture will begin to thicken immediately thanks to the chemical reaction. Whisk in the lime zest if using. The filling should be smooth, thick, and uniform.
Fill the Crusts
Pour the filling evenly into the pre-baked crusts, filling almost to the top.
Bake
Bake for 12-15 minutes until the filling is set around the edges but still slightly jiggly in the very center. They will continue to set as they cool.
Cool and Chill
Let the mini pies cool completely in the pan on a wire rack. Then refrigerate for at least 2 hours, preferably 4, until completely chilled and set.
Make the Whipped Cream
In a chilled bowl, beat the cold heavy cream, powdered sugar, and vanilla extract with an electric mixer until stiff peaks form.
Top and Garnish
Pipe or spoon the whipped cream onto each mini pie. Garnish with lime zest curls, tiny lime slices, or mint leaves.
Serve and Store
Serve chilled. Store in an airtight container in the refrigerator for up to 3 days.
Pro-Tips for Mini Key Lime Pie Greatness
- Use Fresh Lime Juice: Bottled lime juice has a flat, metallic taste. Fresh Key limes (or regular limes) are non-negotiable for that bright, authentic flavor.
- Press Crusts Firmly: A compact crust prevents crumbling when you remove the mini pies from the pan.
- Don’t Overbake: The filling should still have a slight jiggle in the center when you pull them out. They’ll set perfectly as they cool.
- Chill Thoroughly: Mini key lime pies need time to set up properly. At least 2 hours, preferably 4.
- Zest First, Juice Second: Always zest your limes before juicing—it’s nearly impossible to zest a limp, juiced lime.
