Ingredients
Gather your ingredients to create this unforgettable key lime pie. Precision matters here for the best outcome.

- 11 (about 160g) full-sheet graham crackers
- 1/2 cup (62g) salted macadamia nuts (roasted preferred)
- 2 Tablespoons (25g) granulated sugar
- 5 Tablespoons (71g) unsalted butter, melted
For the Key Lime Filling:
- 28 ounces (two 14-ounce cans/793g) full-fat sweetened condensed milk
- 1 cup (240ml) key lime juice
- 4 large egg yolks
- 1 teaspoon key lime zest
Optional Garnish:

Notes & Substitutions
Crafting the perfect key lime pie begins with understanding your ingredients. These notes ensure your pie turns out beautifully every time.
- Graham Cracker Choices: Use good quality full-sheet graham crackers for the best flavor and texture in your crust. Any brand works well.
- Macadamia Nut Importance: Salted and roasted macadamia nuts provide incredible depth and flavor to the crust. Do not skip them; they are key to the unique taste.
- Sweetened Condensed Milk: Always opt for full-fat sweetened condensed milk. It provides the essential richness and creamy texture for the filling. Do not use evaporated milk.
- Key Lime Juice Options: Freshly squeezed key lime juice offers the brightest flavor. If fresh key limes are hard to find, “Nellie & Joe’s” brand bottled key lime juice is an excellent, authentic alternative.
- Egg Yolks’ Role: The egg yolks are crucial. They enrich the filling, give it a beautiful pale yellow color, and act as a natural thickener, ensuring your pie sets perfectly. Understanding the emulsifying properties of egg yolks reveals why they are indispensable for smooth custards.
- Alternative Crusts: If macadamia nuts aren’t your preference, you can use vanilla wafer cookies or Biscoff cookies for a delicious alternative crust. Simply follow the same ratio of crumbs to butter and sugar.
- Leftover Egg Whites: Don’t waste your egg whites! Use them to make a lovely meringue topping for your pie, or save them for another recipe like meringues or an omelet.
Equipment
Having the right tools makes baking this amazing key lime pie a breeze. You likely have most of these on hand.
- 9-inch pie dish: Essential for baking and serving.
- Food processor: Makes quick work of crushing graham crackers and nuts for the crust.
- Small mixing bowls: For combining crust ingredients and the pie filling.
- Whisk or electric mixer: To thoroughly combine the filling ingredients until smooth.
- Measuring cups and spoons: For accurate ingredient portions.
- Citrus juicer: To extract juice efficiently from key limes if using fresh.
- Microplane zester: For finely grating the delicate key lime zest.
Instructions
Follow these simple steps to create a show-stopping key lime pie with that irresistible macadamia crust. Precision and patience are your best friends here.
- Prepare the Crust: Preheat your oven to 350°F (177°C). In a food processor, pulse the graham crackers and macadamia nuts together until they form coarse crumbs. A few slightly larger pieces of nuts are perfectly fine and add texture. Transfer the crumbs to a medium bowl and stir in the granulated sugar. Add the melted unsalted butter and mix until the mixture is thoroughly combined. It will be thick, coarse, and sandy. Break up any large chunks. Pour this mixture into an ungreased 9-inch pie dish. Use your hands to firmly pat the crumbs down onto the bottom and up the sides of the dish, forming a solid crust. Apply medium pressure, patting until the mixture is no longer crumbly. For stability, use a small flat-bottomed measuring cup to help press down the bottom and smooth it. Run a spoon around the bottom “corner” where the edge and bottom meet to create a rounded crust edge; this helps prevent the crust from crumbling when sliced.
- Pre-bake the Crust: Place the prepared crust in the preheated oven. Bake for 8 minutes. This step helps set the crust and prevents it from becoming soggy. Carefully remove the crust from the oven and set it aside. Leave the oven on; you will use it again shortly for the pie.
- Make the Filling: While the crust is still warm, prepare the luscious key lime filling. In a medium bowl, whisk together the full-fat sweetened condensed milk, key lime juice, and the four large egg yolks. You can use a hand whisk or an electric mixer for this step until the mixture is smooth and fully combined. Stir in the fresh key lime zest, which brightens the overall flavor profile.
- Bake the Pie: Pour the freshly made key lime filling directly into the warm, pre-baked crust in the pie dish. Return the pie dish to the oven. Bake for 18–20 minutes, or until the center of the pie is only slightly jiggly when you gently nudge the dish. The edges should appear set. It is crucial to avoid overbaking the pie, as this can lead to a less creamy texture.
- Chill Thoroughly: Remove the finished key lime pie from the oven and place it on a wire rack to cool completely at room temperature. Once the pie is fully cooled, cover it tightly with plastic wrap or aluminum foil. Transfer the covered pie to the refrigerator and chill for at least 1 hour, or preferably for 3 hours, before serving. Proper chilling ensures the pie sets perfectly and is easier to slice. You can chill it for up to 3 days if preparing in advance.
- Garnish and Serve: Once thoroughly chilled, it’s time to garnish your beautiful key lime pie. You can prepare optional whipped cream by whipping heavy cream with a touch of sugar and vanilla. Decorate the pie as desired with dollops of whipped cream, additional key lime zest, thin slices of key lime, or even a sprinkle of chopped macadamia nuts. Slice into wedges and serve your chilled, refreshing dessert.
Pro Tips & Troubleshooting
Ensure your delicious key lime pie turns out perfectly every time with these expert tips and common troubleshooting solutions.
- Achieving Perfect Set: The “slight jiggle” test is key. The center should resemble a very soft jelly, not liquid. It will firm up completely as it cools and chills.
- Preventing Soggy Crust: Pre-baking the macadamia graham cracker crust for 8 minutes creates a barrier, helping to prevent it from becoming soft or soggy from the filling.
- Zesting & Juicing Efficiency: For maximum zest, use a microplane zester before cutting and juicing your key limes. Roll the limes on your counter before juicing to release more liquid.
- Don’t Overbake: Overbaking a key lime pie can result in a rubbery texture. Watch for the slight jiggle; once the edges are set and the center barely moves, remove it.
- Using Regular Limes: You can use regular Persian limes, but increase the zest to 1.5-2 teaspoons and consider adding a tiny pinch of green food coloring for a more “key lime” look. Discover the culinary differences between key limes and Persian limes to understand how each contributes to flavor. The flavor will be slightly less tart.
- Crust Shaping Techniques: For a perfect crust, use the flat bottom of a measuring cup to press the crumbs firmly into the bottom. For the sides, use your fingers to press them up, then use the back of a spoon to create a smooth, rounded edge.
Serving, Storage & Variations
Once your homemade key lime pie is perfectly set and chilled, it’s time to enjoy it! Here’s how to serve, store, and even get creative with this delightful dessert.
- Serving Suggestions: Serve your key lime pie chilled, directly from the refrigerator. It pairs wonderfully with a dollop of freshly whipped cream or a light meringue topping. A garnish of fresh key lime zest or a thin lime slice adds a beautiful touch.
- Storage Instructions: Store any leftover key lime pie tightly covered with plastic wrap in the refrigerator. It will stay fresh and delicious for up to 1 week.
- Freezing Baked Pie: You can freeze a baked and cooled pie. Wrap it tightly in plastic wrap, then in foil, and freeze for up to 1 month. Thaw in the refrigerator overnight before serving.
- Flavor Variations: Introduce new dimensions to your key lime pie. Add a touch of coconut extract to the filling for a tropical twist, or grated fresh ginger to the crust for a warming spice. Other citrus juices, like lemon or grapefruit, can also be explored for a unique pie.
- Topping Alternatives: Beyond whipped cream, consider a toasted meringue topping for a traditional look, or a sprinkle of toasted coconut flakes for added texture and flavor. Fresh berries like raspberries or blueberries also make a vibrant garnish.
- Individual Pies: Adapt this recipe easily for individual servings. Press the crust mixture into muffin tins lined with paper cups or small ramekins, adjusting baking times accordingly. This creates perfect mini key lime pies for gatherings.
