Heavenly No-Bake Mini Key Lime Pies are little bites of pure sunshine wrapped in a crumbly graham cracker crust. The tangy, creamy lime filling is perfectly balanced with a touch of sweetness, making these pies irresistibly refreshing. These mini treats are smooth, zesty, and just the right size to enjoy as a quick, feel-good dessert.
I love these pies because they’re so easy to whip up—no oven needed! I usually make them on a warm afternoon when I want a cool, light dessert without too much fuss. Plus, having them in mini form means everyone can grab their own, and there’s no need to slice or share awkwardly.
My favorite way to enjoy them is chilled, straight from the fridge, with a little dollop of whipped cream on top and a sprinkle of lime zest for some extra zing. They’re perfect for summer barbecues, casual get-togethers, or whenever you feel like a sweet, tart treat that doesn’t weigh you down. I always make a double batch because they disappear so fast!
Key Ingredients & Substitutions
Graham Cracker Crumbs: These give the crust its classic crunch and slight sweetness. If you can’t find graham crackers, crushed digestive biscuits or vanilla wafers work well too.
Sweetened Condensed Milk: This adds creamy sweetness and helps thicken the filling. You can try coconut condensed milk for a dairy-free option, but it will change the flavor slightly.
Key Lime Juice: The heart of this pie! Fresh key lime juice provides the authentic tang. If key limes aren’t available, regular lime juice is a fine substitute, just expect a slightly different taste.
Heavy Whipping Cream: Whipping this up gives the filling a light and fluffy texture. If you prefer, you can use canned coconut cream whipped for a dairy-free choice.
How Do You Get the Perfect Crust and Smooth Filling?
Getting the crust and filling just right ensures those mini pies hold together and taste great.
- For the crust: Mix the crumbs and sugar well, then add melted butter. Press firmly into the mini tin’s base and sides. Pressing firmly is key so the crust holds when you remove the pies.
- For the filling: Whisk the condensed milk, lime juice, zest, and vanilla first to combine the flavors and start thickening. Then gently fold in softly whipped cream. Folding keeps it light and airy instead of dense.
- Chilling: Let the pies set in the fridge for several hours. This step helps them firm up into the perfect creamy texture that slices easily and tastes refreshing.
Equipment You’ll Need
- Mini muffin tin – I find this perfect for making evenly sized mini pies that are easy to serve and eat.
- Mixing bowls – Use a medium bowl for the crust mixture and a large one for the filling and whipped cream.
- Measuring cups and spoons – Precise measurements help get the balance of flavors just right.
- Whisk or hand mixer – Makes whipping the cream quick and easy, creating a fluffy topping.
- Spatula – Helps fold the whipped cream into the lime mixture gently without deflating it.
- Refrigerator – Needed to chill and set the pies so they stay firm and delicious.
Flavor Variations & Add-Ins
- Coconut Lime: Stir in 1/4 cup shredded coconut into the lime filling for a tropical twist.
- Berry Topping: Add a few fresh berries or swirl berry jam into the filling before setting for extra flavor and color.
- Ginger Zest: Mix in a pinch of ground ginger or add ginger snaps crust for a spicy kick.
- Almond Flavor: Swap vanilla extract for almond extract for a nuttier, richer taste.

How Much Time Will You Need?
This recipe takes about 15 minutes of preparation time, plus 3 to 4 hours in the refrigerator to chill and set. If you have extra time, chilling overnight is even better to let flavors meld perfectly.
Step-by-Step Instructions:
1. Make the Crust:
In a medium bowl, mix graham cracker crumbs, sugar, and melted butter until all crumbs are moistened. Firmly press about 2 tablespoons of this mixture into the bottoms and sides of each cup in your mini muffin tin. Place the tray in the fridge while you make the filling to let the crust chill and firm up.
2. Prepare the Lime Filling:
In a separate bowl, whisk together the sweetened condensed milk, fresh key lime juice, lime zest, and vanilla extract. The acidity in the lime juice will cause the mixture to thicken slightly—this is just right!
3. Whip the Cream:
Using a hand mixer or whisk, beat the chilled heavy cream with the powdered sugar until soft peaks form. This means the cream will hold its shape but still be soft to the touch.
4. Combine Filling and Cream:
Gently fold the whipped cream into the lime mixture. Folding (instead of stirring vigorously) helps keep the filling light and fluffy, ensuring a creamy texture.
5. Assemble & Chill:
Spoon the creamy filling evenly into each chilled graham cracker crust. Smooth the tops with a spoon or spatula. Cover the tray and refrigerate for at least 3 to 4 hours, or overnight for best results.
6. Add Final Touches & Serve:
Before serving, add a dollop or pipe some extra whipped cream on top of each mini pie. Garnish with a thin slice of key lime and a sprinkle of lime zest for that fresh, vibrant finish. Serve chilled and enjoy the bright, creamy, and refreshing taste of these mini key lime pies!
Can I Use Regular Limes Instead of Key Limes?
Yes! Regular lime juice works perfectly if you can’t find key limes, though the flavor will be slightly less tart and floral. Just use the same amount called for in the recipe.
Can I Make These Mini Pies Ahead of Time?
Absolutely! These pies actually taste better after chilling overnight as the flavors have more time to blend. Just cover them tightly and keep refrigerated until you’re ready to serve.
How Should I Store Leftovers?
Store any leftover mini pies in an airtight container in the refrigerator for up to 3 days. Keep the whipped cream topping fresh by adding it just before serving if possible.
Can I Use Pre-made Whipped Cream?
Yes, store-bought whipped cream can be used as a convenient topping. For the filling, though, freshly whipped cream folded into the lime mixture gives the best texture and flavor.
