If you love key lime pie but want something easier to serve at a party, this Mini Key Lime Pies Recipe is exactly what you need.
Each one has a buttery graham cracker crust and a creamy, tangy lime filling packed into a single perfect bite.
They come together with just a handful of ingredients, and there is no fussy slicing or crimping involved.
I make a batch of these whenever I need a dessert that looks impressive but takes almost no effort.
If you are watching carbs, I also have a Keto Key Lime Pie that swaps the graham cracker crust for a low carb version.

Recommended Products for This Recipe
These are a few products I personally use and recommend whenever I make these mini pies, based on years of testing this recipe in my own kitchen.
1. Nordic Ware Nonstick Muffin Pan
A heavy gauge muffin pan heats evenly, so every crust bakes to the same golden color without any pale or overly dark spots.
It also releases the mini pies cleanly, which matters since these do not have a paper liner in every method.
2. OXO Citrus Juicer
Fresh key limes are tiny and tricky to juice by hand, so a small citrus juicer saves your fingers and gets every last drop out.
It makes a real difference in flavor compared to bottled juice.
3. Microplane Premium Zester
This zester grabs just the fragrant outer peel of the lime without any of the bitter white pith.
The zest adds a big flavor boost to both the filling and the topping.
4. KitchenAid Hand Mixer
Whipping the fresh cream for topping is so much faster and more consistent with a good hand mixer.
It gives you stiff, stable peaks in just a couple of minutes.
5. Nielsen Massey Pure Vanilla Extract
A splash of good vanilla in the whipped cream rounds out the tartness of the lime beautifully.
This brand has a clean, rich flavor that is worth the extra cost.
I used my Butter Pie Crust technique as the starting point for perfecting this graham cracker version.
Step-by-Step Instructions: How to Make Mini Key Lime Pies
1. Prepare the pan and preheat the oven
- Preheat your oven to 350 degrees Fahrenheit.
- Line a 12 count muffin pan with paper or foil cupcake liners.
- Set the pan aside on your counter so it is ready as soon as the crust mixture is done.
2. Make the graham cracker crust
- In a medium mixing bowl, combine the graham cracker crumbs and granulated sugar.
- Stir in the melted butter until every bit of the crumb mixture looks moistened, similar to the texture of wet sand.
- Divide the mixture evenly among the 12 lined muffin cups, about 1 heaping tablespoon in each.
- Use the bottom of a small measuring cup or a shot glass to press the crumbs firmly and evenly into the bottom of each liner.
- Bake the crusts for 7 to 8 minutes, until they look set and lightly golden at the edges.
- Remove the pan from the oven and set it on a wire rack to cool slightly while you make the filling.
- Reduce the oven temperature to 325 degrees Fahrenheit.
3. Mix the key lime filling
- In a separate medium bowl, add the egg yolks and lime zest.
- Using a hand mixer, beat the egg yolks and zest together on medium speed for about 2 minutes, until the mixture looks pale and slightly thickened.
- Pour in the sweetened condensed milk and mix on low speed until fully combined.
- Slowly stream in the key lime juice while mixing on low, then continue mixing just until the filling is smooth and uniform.
- Avoid overmixing at this stage, since you only want everything fully incorporated.
4. Fill and bake the mini pies
- Pour or spoon the filling evenly over the cooled crusts, filling each liner almost to the top.
- Return the pan to the oven and bake at 325 degrees Fahrenheit for 10 to 12 minutes.
- The filling should look mostly set with just the slightest jiggle in the very center, and it should not brown or puff up.
- Remove the pan from the oven and let the pies cool at room temperature for about 30 minutes.
5. Chill and top the pies
- Once the pies have cooled to room temperature, transfer the muffin pan to the refrigerator.
- Chill for at least 2 hours, or until the filling is fully set and cold.
- Just before serving, add the heavy whipping cream and powdered sugar to a large bowl.
- Beat with a hand mixer on medium high speed until soft peaks form, about 2 to 3 minutes.
- Top each chilled mini pie with a dollop of whipped cream and a sprinkle of fresh lime zest.
- Gently remove the pies from the liners if desired, then serve cold.

Tips for The Best Mini Key Lime Pies
A few small details make a big difference in how these little pies turn out.
- Use room temperature egg yolks so they blend more smoothly into the condensed milk
- Do not skip the crust pre-bake, since it keeps the base from getting soggy
- Watch the filling closely near the end of baking, it should jiggle only slightly in the center
- Let the pies cool completely before chilling for the cleanest slices and texture
- Zest the limes before you juice them, since it is much harder to zest a juiced lime
- Bottled key lime juice works in a pinch, but fresh juice gives the brightest flavor
These tips are similar to what I share in my Sugar Free Key Lime Pie recipe, which uses the same baking method.
Serving Suggestions
These mini pies are rich and tangy, so they pair well with light, fresh sides or drinks.
- Serve alongside a bowl of fresh berries for a bright, colorful dessert spread
- Pair with iced tea or lemonade for a warm weather gathering
- Add a plate of Key Lime Pie Cookies for a themed dessert table
- Set them out with coffee for an easy after dinner treat
- Add a few mint leaves and extra lime slices for a pretty garnish
Variations of Mini Key Lime Pies
Once you have the base recipe down, there are plenty of ways to switch things up.
- Swap the graham cracker crust for crushed shortbread cookies for a buttery twist
- Add a thin layer of raspberry jam under the filling for a fruity surprise
- Top with toasted coconut instead of whipped cream for a tropical version
- Drizzle melted white chocolate over the tops before serving
- Use a mix of lime and lemon juice if key limes are hard to find
- Make them dairy free by using coconut cream in place of the whipped cream topping
My Lime Crinkle Cookies use the same fresh lime zest and juice combination if you want more citrus desserts in your rotation.
Storage and Reheating
These pies are meant to be served cold, so storage is simple and there is no reheating involved.
- Store leftover pies in an airtight container in the refrigerator for up to 4 days
- Add the whipped cream topping only right before serving if you plan to store them longer
- Freeze the unfrosted pies in a single layer, then transfer to a freezer bag for up to 2 months
- Thaw frozen pies overnight in the refrigerator before adding fresh whipped cream and serving
- Avoid leaving the pies at room temperature for more than 2 hours

FAQs About Mini Key Lime Pies
1. Can I use regular limes instead of key limes?
Yes, regular limes will work fine if you cannot find key limes.
The flavor will be slightly less tart and floral, but the texture and result will still be delicious.
2. Why is my filling not setting properly?
This usually happens if the filling was underbaked or the pies were not chilled long enough.
Make sure to bake until the center only jiggles slightly, then chill for a full 2 hours before serving.
3. Can I make these ahead of time?
Absolutely, these mini pies are a great make ahead dessert.
You can prepare them up to 2 days in advance and add the whipped cream topping right before serving.
4. Do I have to use egg yolks, or can I use whole eggs?
Egg yolks give the filling its rich, custardy texture, so they work best for this recipe.
Using whole eggs can make the filling a bit lighter and less creamy, so yolks are recommended.
5. Can I make this recipe in a mini muffin tin instead?
Yes, a mini muffin tin works well and will yield about 24 bite sized pies.
Just reduce the baking time by a few minutes and watch them closely, since smaller portions bake faster.
If you love the tart and sweet combination in this recipe, my Cranberry Lime Pie is another great way to enjoy that same flavor pairing.
