How to Make It
Note: This is an overview. See recipe card below this post for ingredient quantities and full instructions.
Step 1: Prepare the Crust
Start by crushing your graham crackers into fine crumbs—don’t worry if it’s not perfect; texture adds charm! Mix the crumbs with melted butter until they resemble wet sand. Press this mixture firmly into the bottom of your pan to create a sturdy base. Think of it as building the foundation for all the zesty goodness coming next.
Step 2: Whip Up the Filling
In a large bowl, whisk together sweetened condensed milk, key lime juice, and zest until smooth and glossy. The aroma will transport you straight to a tropical beach (minus the sunscreen). Pour this dreamy mixture over the crust and spread it evenly. Take your time here—a little patience ensures every bite is perfectly balanced.

Step 3: Chill and Set
Pop the pan into the fridge for at least 4 hours, or overnight if you’re feeling extra patient. This step is crucial because it allows the flavors to meld and the filling to firm up beautifully. While waiting, channel your inner zen—it’s worth it!
Step 4: Add Finishing Touches
Once set, slice the bars into neat squares. For an extra touch of elegance, garnish with whipped cream, more lime zest, or even a sprinkle of crushed graham crackers. Serve chilled and watch everyone swoon over these tangy treats.
Pro Tips
- Use fresh key limes whenever possible for the brightest flavor—bottled juice works in a pinch but lacks that wow factor.
- If you don’t have key limes, regular Persian limes can be substituted, though the taste will be slightly less floral.
- To crush graham crackers easily, place them in a resealable bag and use a rolling pin or the bottom of a glass.
- For cleaner cuts, dip your knife in hot water before slicing through the bars.
- Double the batch if serving a crowd—they disappear faster than you’d think!
Storage
- Store leftovers in an airtight container in the refrigerator for up to 5 days.
- Freeze individual portions wrapped tightly in plastic wrap for up to 2 months. Thaw in the fridge before serving.
- Keep away from strong-smelling foods in the fridge to preserve the delicate lime flavor.
