The Process for Making Lemon Key Lime Pie Bars

Making Lemon Key Lime Pie Bars is not only straightforward, but it’s also an enjoyable experience. You’ll see how quickly the process comes together, and before you know it, you’ll have a delicious dessert ready to chill. Let’s dive into the steps:
- Preheat your oven to 350° F. Line a 9-inch square pan with parchment paper to make removal easy later on.
- In a food processor, pulse the Ritz crackers along with the brown sugar until they turn into fine crumbs. It should resemble a sandy texture. Next, add the melted butter and 2 teaspoons of vanilla, pulsing again until everything is well combined. You want it to hold together when pressed.
- Press the mixture into the bottom of the prepared pan evenly. Bake for about 18 minutes, or until golden brown. As it bakes, the aroma of the crackers and butter will fill your kitchen, creating the perfect ambiance.
- While the crust is baking, whisk the egg yolks in a medium bowl until smooth and creamy. The color should turn a bright yellow. Then, add the sweetened condensed milk, lime zest, lime juice, lemon juice, and salt, whisking everything together until fully combined.
- Once your crust is done, carefully pour the egg mixture over the crust, spreading evenly. Return to the oven and bake for an additional 15 minutes, until just set on top. You want it to be slightly jiggly in the center.
- Allow the bars to cool slightly, then cover them and chill in the refrigerator for at least 1 to 2 hours. This step is crucial as it allows them to set properly.
- When you’re ready to serve, use an electric mixer to whip the heavy cream until soft peaks form. This should take just a few minutes. Add the honey and 1 teaspoon of vanilla, mixing until combined.
- Swirl the whipped cream over the chilled bars, creating a beautiful topping. It should look fluffy and inviting.
- In a small bowl, mix the lime zest and a pinch of flaky sea salt. Sprinkle this mixture over the top of the bars to finish.
- Slice into squares, and enjoy every bite! The bars will keep chilled in the fridge for up to 5 days, but I doubt they’ll last that long!
