Kitchen Tools You’ll Need
- Mixing bowl
- Measuring cups
- Spoon or spatula
- Muffin tin or mini pie molds
- Whisk
Ingredients
- 1 cup graham cracker crumbs (adds a crunchy texture)
- 2 tablespoons granulated sugar (provides sweetness)
- 5 tablespoons unsalted butter, melted (binds the crust together)
- 1 (14-ounce) can sweetened condensed milk (gives creaminess)
- 1/2 cup key lime juice (adds tartness)
- 1 teaspoon lime zest (enhances lime flavor)
- 1 cup heavy cream, whipped (creates a light texture)
- Optional: fresh lime slices and whipped cream for garnish
How to Make Irresistible No-Bake 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 stir until everything is evenly moistened and resembles wet sand. This mixture should hold together when pressed. Once mixed, it’s ready to be portioned.
Step 2. Next, take a muffin tin or mini pie molds and fill each cavity with the graham cracker mixture. Use your fingers or the back of a spoon to firmly press the crust into the bottom and up the sides of each mold. The crust should feel compact to provide a sturdy base once set.
Step 3. In another bowl, mix the sweetened condensed milk with key lime juice and lime zest. Using a whisk, blend them until smooth and well combined. This mixture will form the filling, and the citrusy lime juice will help thicken it slightly as it rests.
Step 4. Carefully pour the key lime filling into each crust, filling them almost to the top. You want to avoid overfilling, as the filling will need some space to expand slightly as it chills. Smooth the tops gently with a spatula or spoon for an even finish.
Step 5. Place the muffin tin or molds in the refrigerator. Allow the pies to chill for at least a few hours, or until the filling is set. The coolness of the dessert helps meld the flavors and creates a refreshing treat.
Step 6. Once set, if desired, top each mini pie with whipped cream. You can pipe it on for a decorative touch or simply dollop it on. Add fresh lime slices on top for a bright, inviting presentation. The contrast of the white cream against the lime green adds a lovely visual appeal.

Serving Suggestions
These mini key lime pies can be enjoyed in various ways throughout the day. They’re delightful for breakfast if you’re in the mood for a treat, or you can savor them as a refreshing snack during the afternoon. Serving them after family meals can elevate the dining experience, providing a sweet finish. If you happen to have leftovers, they keep nicely in the fridge for a few days, remaining just as delightful.
Pro Tips for Best Results
- Ensure the butter is not too hot when mixing into the crumb mixture, as it may cause it to clump rather than mix evenly.
- Whip the cream until it forms stiff peaks for a light, airy topping.
- Use fresh key lime juice if possible for the best flavor; bottled juice may not match the same brightness.
- Allow the mini pies to chill long enough to ensure the filling sets, enhancing the overall texture.
- Experiment with adding a touch of grated lime zest on top of the whipped cream for extra zing.
- These pies can also be made in advance, allowing flavors to develop and save time on the day of serving.
Common Mistakes to Avoid
- Not pressing the crust firmly enough. If the crust isn’t compacted, it may crumble when you try to remove the pies from the molds. Make sure to press the mixture down firmly.
- Overfilling the pie crust. Filling them to the brim can lead to spillage. Aim for a little below the top to ensure clean edges.
- Insufficient chilling time. Not allowing the mini pies to chill long enough can result in a filling that’s too runny. Be sure to give them ample time to set in the fridge.
- Using low-fat condensed milk. This can lead to a filling that lacks creaminess and flavor. Stick with regular sweetened condensed milk for the best texture and taste.
- Not zesting properly. Using too much white pith when zesting can make the filling bitter. Only grate the green part of the peel for the best flavor.
- Forgetting to taste the filling. Before pouring it into the crust, a quick taste can confirm if it has the desired sweetness and tang. Adjust with a bit more lime juice if needed.
Variations & Substitutions
You might consider experimenting with the crust by using vanilla wafer cookies for a different flavor profile. For a more indulgent option, try adding a layer of chocolate ganache beneath the filling. If you prefer a less tart dessert, blend in a little more sweetened condensed milk. You could also make these mini pies larger in regular pie tins, adjusting the setting time accordingly.
Storage & Reheating
These mini pies can be stored in the refrigerator for up to 3-4 days, covered with plastic wrap or in an airtight container. They do not hold their texture well at room temperature for long periods, so it’s best to keep them chilled. Freezing is not recommended as it can alter the texture of the crust and filling. If needed, serve them straight from the fridge for optimal enjoyment.
