Ingredients in Key Lime Pie Tartlets
Here’s everything you’ll need to make these tartlets a reality:
Graham Cracker Crumbs
The base of these tartlets is made with a buttery graham cracker crust that adds a satisfying crunch and sweetness to balance out the creamy filling.
Butter
Melted butter is what holds the graham cracker crust together and gives it that deliciously rich flavor.
Sweetened Condensed Milk
This is the secret to the creamy filling! Sweetened condensed milk gives the tartlets their luscious texture and rich sweetness.
Key Lime Juice
The star of the show! Fresh or bottled Key lime juice is the key ingredient that gives these tartlets their bright, tangy flavor. You can use regular lime juice in a pinch, but Key lime juice is truly what makes these tartlets special.
Egg Yolks
Egg yolks help thicken the filling and create that smooth, custard-like texture that makes Key lime pie so irresistible.
Whipped Cream
A dollop of freshly whipped cream is the perfect topping for these tartlets, adding a light, airy texture to balance the richness of the filling.

Instructions
Ready to make some mini Key lime pie magic? Here’s how:
1. Prepare the Crust
In a medium bowl, combine the graham cracker crumbs, melted butter, and a little sugar. Mix until the crumbs are evenly coated. Press this mixture into the bottoms and up the sides of your tartlet pans. Bake at 350°F for about 8 minutes until golden and set aside to cool.
2. Make the Filling
In another bowl, whisk together the sweetened condensed milk, egg yolks, and Key lime juice until fully combined. The mixture should be smooth and thick. Pour this filling into the cooled tart crusts, distributing it evenly.
3. Bake the Tartlets
Bake the tartlets at 350°F for about 10-12 minutes. The filling should set but still have a slight jiggle in the center when done. Let them cool completely on a wire rack.
4. Chill the Tartlets
Once cooled, place the tartlets in the refrigerator for at least 2 hours to let the filling set and get that perfect creamy texture.
5. Add the Whipped Cream
Before serving, top each tartlet with a dollop of freshly whipped cream. For an extra touch, you can garnish with lime zest or a lime slice.
6. Serve & Enjoy!
Serve these little beauties chilled and watch them disappear in seconds!

Additional Tips
Use Fresh Key Limes If You Can
If you have access to fresh Key limes, definitely go for them! They have a more intense, aromatic flavor than regular limes, which makes these tartlets extra special.
No Tartlet Pan? No Problem!
If you don’t have a tartlet pan, you can use a muffin tin to make these. Just be sure to adjust the baking time slightly.
Want to Skip the Baking?
If you prefer a no-bake version, simply make a graham cracker crust in the bottom of each tartlet pan, and refrigerate the crust for 30 minutes before filling with the lime mixture. No need to bake the filling, just chill it to set!
Make Ahead
These tartlets can be made up to 2 days in advance and stored in the fridge. They’re perfect for prepping ahead of time for parties or gatherings.
Customize the Crust
If you want a twist on the traditional graham cracker crust, feel free to experiment with crushed vanilla cookies or even coconut for a tropical flair.
