Kitchen Tools You’ll Need
- Mixing bowl
- Whisk
- Measuring cups
- Measuring spoons
- Muffin tin
- Plastic wrap (optional)
Ingredients
- 1 ½ cups graham cracker crumbs (for a crumbly, buttery crust)
- ⅓ cup granulated sugar (adds sweetness and texture)
- 6 tablespoons unsalted butter, melted (provides moisture and richness)
- 1 cup key lime juice (offers tartness and freshness)
- 2 (14-ounce) cans sweetened condensed milk (adds creaminess and sweetness)
- 4 large egg yolks (helps in thickening and provides richness)
- Homemade whipped cream (optional, adds a light, creamy topping)
How to Make The BEST Mini Key Lime Pies
Step 1. Begin by preparing the crust. In a mixing bowl, combine the graham cracker crumbs and granulated sugar. Pour in the melted butter and blend the mixture until evenly moistened. You want a consistency where the crumbs hold together slightly when pressed, resembling damp sand.
Step 2. Next, press the crumb mixture firmly into the bottom of each muffin tin cup. It’s important to pack the crumbs tightly to form a stable base for your pies. A flat measuring cup or your fingers can work nicely here. Ensure the layer is even and smooth for optimal texture.
Step 3. Bake the crusts in a preheated oven until they are golden brown. This step helps to set the crust and enhances their flavor. The edges should look slightly toasted when they are ready. Remove them from the oven and allow them to cool completely before filling.
Step 4. While the crusts are cooling, prepare the filling. In a clean bowl, whisk together the key lime juice, sweetened condensed milk, and egg yolks until fully incorporated. The mixture should be smooth and slightly thickened, with the key lime juice lending a bright greenish-yellow hue.
Step 5. Spoon the filling into the cooled crusts, filling each one to just below the rim. This provides enough space for the filling to rise slightly while baking, yet keeps it contained. Take care to distribute the filling evenly among all the crusts for consistent flavor in each pie.
Step 6. Once filled, return the muffin tin to the oven and bake until the filling is set – it will have a slight jiggle when shaken but shouldn’t be liquidy. The baked filling will develop a softer but firm consistency, signaling it’s ready to cool.
Step 7. After baking, let the mini pies cool to room temperature. Then, refrigerate them for at least a couple of hours to help them set further. The chilling is important as it enhances the flavors and makes them easier to remove from the tin without falling apart.
Step 8. When serving, you may choose to top the pies with homemade whipped cream. This is entirely optional, but it adds a lovely lightness to the tartness of the key lime. A simple dollop atop each mini pie can make for an attractive presentation.

Serving Suggestions
These mini key lime pies are delicious for various occasions. Enjoy them as a light dessert after a family dinner, or they can be perfect for breakfast on a casual weekend. They also make great snacks when you’re craving something sweet but refreshing. Leftovers can easily be stored in the refrigerator and enjoyed later, offering a convenient treat whenever you like.
Pro Tips for Best Results
- Use fresh key lime juice if possible, as it enhances the flavor significantly.
- Ensure the crust is compact before baking; this prevents it from crumbling when serving.
- Allow the pies to sit in the refrigerator long enough for optimal chill to improve flavors.
- If you use store-bought whipped cream, it can save time while still offering great flavor.
- For added texture, consider garnishing with lime zest prior to serving.
- Make sure to cool the crust completely before filling to avoid sogginess.
Common Mistakes to Avoid
- Skipping the Cooling Process: Serving the pies warm may lead to a runny filling. Allowing them to cool and refrigerate helps to firm up the filling, ensuring a better texture.
- Not Packing the Crust Firmly Enough: If the graham cracker crust isn’t tightly packed, it might crumble during serving. Press the mixture down evenly to create a solid base.
- Using Bottled Lime Juice: While convenient, bottled juice often lacks the vibrant flavor of fresh lime. Fresh juice is worth the extra effort for its bold taste.
- Overbaking the Filling: Watch for the filling to be just set. Overbaking can lead to a rubbery texture. It should jiggle slightly and not appear overly firm.
- Neglecting to Chill: Skipping refrigeration can result in softer pies that are difficult to slice. Cool and chill for at least a couple of hours for best results.
- Forgetting the Egg Yolks: Missing egg yolks in the filling can make it less creamy and unbalanced. Ensure you add them for the desired consistency and richness.
Variations & Substitutions
- For a different twist, consider adding a hint of coconut to the crust or filling.
- Use orange or lemon juice instead of key lime for a citrus variation.
- If you want a chocolate element, try drizzling ganache over the pies before serving.
- Incorporate crushed nuts into the crust for added flavor and crunch.
Storage & Reheating
Store these mini pies in an airtight container in the refrigerator for up to 3 days. They can also be left at room temperature for a few hours if serving, but refrigeration is ideal to maintain freshness. Freezing is not recommended, as it may alter the texture of the filling and crust. Simply enjoy them cold straight from the fridge, which many find enhances the refreshing flavor.
