Introduction
The joy of a classic key lime pie, made into a perfectly portioned individual dessert. You get that perfect balance of a buttery graham cracker crust with a tart, velvety, and intensely limey filling in every bite. These mini pies are ideal for entertaining and deliver all the iconic flavor without the fuss of slicing a larger pie.
Prep & Cook Time
- Prep Time: 10 minutes
- Cook Time: 20 minutes
- Total Time: 30 minutes
- Servings: 6 mini pies
Ingredients
- 2 cups graham cracker crumbs
- ¼ cup granulated sugar
- ½ cup salted butter (melted)
- 1 cup granulated sugar
- 8 large egg yolks
- ½ cup lime juice
- 1 Tablespoons lime zest
- 7 Tablespoons salted butter (chopped)
Instructions
- Preheat your oven to 350°F (175°C). Grease six 4-ounce ramekins or a standard 6-cup muffin tin.
- In a medium bowl, make the crust by mixing the 2 cups graham cracker crumbs and ¼ cup granulated sugar. Pour in the ½ cup melted salted butter and stir until all crumbs are moistened and the mixture resembles wet sand.
- Firmly press about ¼ cup of the crumb mixture into the bottom and up the sides of each prepared ramekin or muffin cup. Bake the crusts for 5 minutes, then remove from the oven and set aside. Keep the oven on.
- While the crusts bake, prepare the filling. In a heatproof bowl set over a saucepan of simmering water (double boiler), whisk together the 1 cup granulated sugar, 8 large egg yolks, ½ cup lime juice, and 1 Tablespoon lime zest. Cook, whisking constantly, until the mixture thickens enough to coat the back of a spoon, about 8-10 minutes.
- Remove the bowl from the heat. Whisk in the 7 Tablespoons of chopped salted butter, one piece at a time, until fully melted and incorporated into a smooth, thick curd.
- Divide the warm lime curd evenly among the pre-baked crusts. Return the mini pies to the oven and bake for an additional 10-12 minutes, or until the filling is just set (it will jiggle slightly in the center).
- Allow the pies to cool completely at room temperature, then chill in the refrigerator for at least 2 hours before serving.
Variations
- Layered Parfaits: Skip the baking process for a no-bake dessert. Layer the prepared graham cracker crust mixture with the chilled lime curd in small glasses for individual trifles.
- Cookie Crumble Topping: Before serving, sprinkle the tops of the chilled pies with a little extra crushed graham cracker crumbs for added texture.
- Torched Meringue: Top the chilled pies with a dollop of whipped cream or meringue and lightly brown it with a kitchen torch for a classic, elegant finish.
- Frozen Pies: For a frozen treat, freeze the completely cooled and set pies for 3-4 hours. Let sit at room temperature for 5 minutes before serving.
Tips for Success
- Use freshly squeezed lime juice and zest for the brightest, most authentic flavor.
- When cooking the curd over the double boiler, be patient and whisk constantly to prevent the eggs from scrambling.
- Press the crust mixture firmly and evenly into the cups to prevent it from crumbling when you serve the pies.
- The filling will continue to set as it cools. Don’t overbake it; a slight jiggle in the center when you take it out of the oven is perfect.
Storage & Reheating
FAQ
Can I use regular (Persian) limes instead of Key limes?
Absolutely. Standard grocery store limes (Persian limes) work perfectly fine and are easier to juice. The flavor profile is very similar.
Why are there so many egg yolks?
The egg yolks are essential for creating the rich, thick, and custardy texture of the classic filling. They provide structure and richness.
My curd looks lumpy. What happened and can I fix it?
Lumps typically mean the eggs scrambled slightly from too much heat. You can try pressing the curd through a fine-mesh sieve to remove any cooked bits before adding the butter.
Can I make these ahead of time?
Yes, they are an excellent make-ahead dessert. Prepare them completely and store them in the refrigerator for 1-2 days before serving.
Do I have to use ramekins or a muffin tin?
No, you can also use a standard 9-inch pie dish. Simply press all the crust mixture into the dish and follow the same baking instructions, though the final pie will need to chill longer to set completely.
Can I make this without a double boiler?
Yes, you can cook the curd directly in a heavy-bottomed saucepan over very low heat, whisking constantly and vigilantly to prevent scorching. The double boiler method is just more forgiving.
