Heavenly No-Bake Mini Key Lime Pies are like little bursts of bright, tangy sunshine in every bite. These adorable mini pies have a creamy, zesty key lime filling with just the right amount of sweetness, all sitting on a crunchy graham cracker crust. The best part? You don’t have to turn on the oven, making these perfect for any day you want a fresh and easy treat.
I love making these when I want a quick dessert that still feels fancy and special. The no-bake process is super simple, and the mix of tart lime and smooth cream always gets so many compliments. One tip I like to share is to chill them long enough so the filling sets just right — that little extra wait makes a big difference!
These mini pies are great little treats for summer parties, casual get-togethers, or even just a sweet pick-me-up after dinner. I often garnish them with a sprinkle of lime zest or a tiny dollop of whipped cream to add a bit of extra flair. They’re the kind of dessert that everyone loves and that always brings a smile to my face.
Key Ingredients & Substitutions
Graham cracker crumbs: They give the crust its signature crunch and mild sweetness. If you don’t have graham crackers, try digestive biscuits or vanilla wafers—they work well and add a nice flavor twist.
Sweetened condensed milk: This adds sweetness and creaminess. For a dairy-free option, use coconut condensed milk. It changes the flavor slightly but still tastes great.
Key lime juice: Fresh key limes are ideal for that bright, tangy flavor, but regular limes work fine too. If fresh juice isn’t available, bottled lime juice can be used—just pick a good quality one.
Heavy whipping cream: Whipping the cream creates a light, fluffy topping that balances the tart filling. You can substitute coconut cream for a dairy-free whipped topping if needed.
How Can You Get the Perfect Creamy Filling Without Baking?
Mixing the filling right is key to getting that smooth, creamy texture without baking. Here’s how to do it:
- Whisk the condensed milk, lime juice, and zest until the mixture thickens a bit, signaling it’s ready.
- Whip the heavy cream separately until medium peaks form; this adds airiness and lightness.
- Carefully fold half of the whipped cream into the lime mixture. Go slow to keep it fluffy.
- This folding step is important—overmixing can deflate the cream and make the filling dense.
Chill the pies for a couple of hours. This resting time helps the filling set firm enough to hold its shape but stay creamy. I always find a bit of patience here pays off with a rich, light texture.
Equipment You’ll Need
- Mini muffin tin or small tart pans – I recommend these because they create perfect, individual-sized pies.
- Mixing bowls – for combining the crust ingredients and filling; a medium bowl works best for the crust mixture.
- Whisk – I love using a whisk to smoothly blend the lime mixture and incorporate the whipped cream without knocking out too much air.
- Electric hand or stand mixer – makes whipping the cream quick and effortless, but you can also whisk by hand if you prefer.
- Spoon or piping bag – for filling the mini crusts neatly, especially when adding the whipped cream topping.
- Refrigerator – essential for chilling the pies and letting the filling set up properly.
Flavor Variations & Add-Ins
- Berry swirl: Mix in a few spoonfuls of berry jam or swirl fresh berry puree into the lime filling for a fruity twist.
- Coconut cream topping: Substitute whipped cream with sweetened coconut cream for a tropical flavor and dairy-free option.
- Ginger Crust: Use ginger snap cookies instead of graham crackers to add a spicy kick to the crust.
- Extra zest: Add a little more lime zest or even lemon zest for an extra zing that accentuates the citrus flavor.

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare, plus at least 2 hours in the refrigerator to chill and set. It’s simple and perfect when you want a quick dessert with little fuss!
Step-by-Step Instructions:
1. Make the Crust:
In a medium bowl, mix the graham cracker crumbs, melted butter, and granulated sugar until it looks like wet sand. Press this mixture firmly into the bottoms and slightly up the sides of a mini muffin tin lined with paper liners or greased mini tart pans. Pop them into the fridge while you get the filling ready.
2. Prepare the Lime Filling:
In a bowl, whisk together the sweetened condensed milk, fresh key lime juice, and lime zest. Stir until the mixture is smooth and begins to thicken a little.
3. Whip the Cream:
Using an electric mixer or a whisk, whip the cold heavy cream with powdered sugar until medium peaks form. That means when you lift the whisk, soft peaks that hold their shape appear but are still a bit soft.
4. Combine Filling and Cream:
Gently fold about half of the whipped cream into the lime mixture, stirring slowly so it blends evenly and stays light and airy.
5. Assemble and Chill:
Spoon the lime filling into the chilled crusts, filling each about three-quarters full. Put the pies back in the fridge for at least 2 hours so they set up nicely.
6. Add Topping and Garnish:
Before serving, add the remaining whipped cream on top of each mini pie—pipe it for a fancy look or simply dollop it on. Garnish with a small slice or wedge of lime and a sprinkle of lime zest for a fresh, beautiful finish.
7. Serve and Enjoy!
Enjoy these tangy, creamy, and crunchy mini pies chilled. They’re perfect for parties, warm days, or anytime you want a little slice of sunshine!
Can I Use Regular Lime Juice Instead of Key Lime Juice?
Yes! Regular lime juice works just fine and is more widely available. Just make sure it’s fresh for the best flavor. Bottled juice can be used in a pinch but may be less vibrant.
How Long Can I Store These Mini Key Lime Pies?
Store the pies in an airtight container in the refrigerator for up to 3 days. They taste best fresh but will keep their texture and flavor for a couple of days.
Can I Make These Ahead of Time?
Absolutely! Make the crusts and filling a day ahead, then chill overnight. Add the whipped cream topping right before serving to keep it fresh and fluffy.
Can I Substitute the Graham Cracker Crust?
Yes, you can use crushed digestive biscuits or vanilla wafers as a tasty alternative. Just mix with melted butter and sugar the same way to form the crust.
