These mini key lime pies are the quickest way to recreate a sunny Florida treat without turning on the oven. Each one packs a refreshing punch—creamy sweet filling, zesty citrus, and a buttery graham crust—ideal when you need an easy dessert for casual gatherings or summer evenings.
When I first made these for an outdoor family picnic, everyone was hooked by the bright flavors and adorable presentation. Now they are requested for birthdays and backyard barbecues alike.
Ingredients
- Graham cracker crumbs: create that classic crumbly crust and are best when they are fresh and finely crushed to prevent a gritty texture
- Granulated sugar: sweetens the crust and helps it set firm
- Unsalted butter melted: binds the crust mixture together for sturdy mini pies always use high quality butter for the best flavor
- Sweetened condensed milk: gives the filling its rich creamy sweetness make sure to use the full fat version for the right texture
- Key lime juice: adds that essential tart citrus punch fresh squeezed makes a big difference in taste a citrus reamer makes juicing easy
- Lime zest: infuses even more flavor and a hint of color always zest before juicing for best results
- Heavy cream: whips up into a soft cloud for the topping use cream labeled as heavy or whipping for ideal volume
- Powdered sugar: sweetens and stabilizes the whipped cream sift it first for perfectly smooth results
- Extra lime zest for garnish: adds a burst of color and aroma
Step-by-Step Instructions
- Prepare the Crust:
- Mix graham cracker crumbs sugar and melted butter thoroughly in a medium bowl until every crumb is moistened for even texture. Firmly press the mixture into the bottoms and up the sides of mini tart pans with your fingers or the bottom of a small glass for best definition. Chill in the refrigerator for at least one hour to fully set and keep crusts intact when unmolding.
- Make the Filling:
- In a large bowl whisk together the sweetened condensed milk key lime juice and lime zest until completely smooth and thickened. The mixture should start to resist the whisk as it thickens. Evenly spoon or pour the filling into the chilled crusts and smooth the tops with a spatula for an even layer.
- Whip the Cream:
- In a separate chilled bowl whip heavy cream and powdered sugar using an electric hand mixer on medium high speed. Beat until stiff peaks form and the cream holds its shape when you lift the beaters. Do not over whip or the cream may become grainy.
- Assemble and Garnish:
- Pipe or spoon a generous swirl of whipped cream on each mini pie. Sprinkle with a pinch of extra lime zest over the top for color and a pop of aromatics.
- Chill and Serve:
- Place assembled pies back in the refrigerator for at least two hours to allow the filling to become firm. For the neatest slices and best texture, serve well chilled.

Sweetened condensed milk always brings back memories of my grandmother’s desserts she believed nothing beat that creamy sweetness for pie fillings. I love watching my nieces delight when they take their first bite and get that burst of tart lime with the smooth cream.
Storage Tips
Mini key lime pies keep well in the refrigerator for up to three days just cover tightly with plastic wrap to prevent the whipped cream from absorbing any fridge odors. If you want to store them longer you can freeze them without the whipped cream topping then add fresh cream before serving for a just made feel.
Ingredient Substitutions
If key limes are unavailable regular limes work well or a mix of lime and lemon for extra complexity. For a gluten free version swap graham crackers with your favorite gluten free cookies crushed finely.
Serving Suggestions
I like to serve these pies with a thin slice of lime or a curl of zest on top for a more decorative finish. For parties arrange them on a platter with fresh berries to make the color pop even more and add a few mint leaves for a touch of herbal contrast.
