Step-by-step Preparation for the Best Key Lime Pie
Preheat the oven
First things first—set your oven to 350°F (175°C). Why is this important? Preheating ensures that your pie bakes evenly, giving you that deliciously creamy texture we're all after in the best key lime pie. While the oven is heating, let's dive into the filling!
Combine condensed milk and sour cream
In a large mixing bowl, whisk together two cans (14 ounces each) of sweetened condensed milk with half a cup of sour cream. This combination creates the rich base of your pie. Whisk until the mixture is smooth and creamy. The ideal consistency will look velvety and a bit thick, inviting you to take a taste (a little quality control never hurt anyone!).
Add the key lime juice
Next, it’s time to bring the zesty flavor. Pour in three-quarters of a cup of key lime juice. If you can, go for freshly squeezed juice—it enhances the flavor profile significantly. Once you add this citrus goodness, continue whisking until everything is well combined and the mixture is perfectly smooth. This step is crucial, as the key lime juice gives that refreshing tang that makes key lime pie so irresistible.
Pour filling into the pie crust
Take a moment to admire the mixture you just created; it's beautiful! Now, pour the filling into your pre-prepared graham cracker crust. Make sure to spread it evenly for a consistent finish.

Bake (optional) and cool
Here’s where you can tweak your approach slightly. You have the option to bake the pie for 6 to 8 minutes, which helps any bubbles that may have formed to rise and burst. If you choose to skip this step, don’t worry—the pie will still set beautifully without baking. After this, let the pie cool on the counter before transferring it to the refrigerator. For best results, chill it for at least four hours.
Prepare the whipped cream topping
While the pie cools, let’s whip up a glorious topping! In a medium bowl, beat 1.5 cups of heavy whipping cream with half a cup of powdered sugar until stiff peaks form. This creamy layer will perfectly balance the tangy filling. Feel free to taste along the way—just because!
Serve and enjoy
Once your pie is set and chilled, it’s time for the grand reveal. Slice up the pie, and generously top each piece with that luscious whipped cream. As you serve this beauty, take a moment to soak in the delight from your friends and family—all thanks to your efforts in creating the best key lime pie they’ve ever tasted! Now, sit back, relax, and enjoy every zesty bite.
