Perfect for warm days or any occasion that calls for a zesty treat, these bars are easy to whip up and unbelievably delicious. Follow these steps, and you’ll have an impressive dessert ready to share with friends and family.
Gather Your Ingredients
Before diving into the process, it’s essential to gather all your ingredients. Here’s what you need:
- 2 sleeves Ritz crackers
- 2 tablespoons light or dark brown sugar
- 1 stick (8 tablespoons) salted butter, melted
- 3 teaspoons vanilla extract
- 5 large egg yolks
- 1 ¾ cups sweetened condensed milk
- 1 tablespoon lime zest, plus ⅔ cup lime juice
- 3 tablespoons lemon or pink lemon juice (or additional lime juice)
- ¼ teaspoon kosher salt
- 1 cup heavy cream
- 1-2 tablespoons honey
Tip: Use fresh lemons and key limes for the best flavor!
Create the Crust
Start by preheating your oven to 350°F (175°C) and lining a 9-inch square pan with parchment paper. This makes for easy lifting and cleanup. Next, crush the Ritz crackers into fine crumbs. You can do this by pulsing them in a food processor or placing them in a plastic bag and rolling over them with a rolling pin.
Once crumbed, combine the Ritz crumbs with brown sugar and melted butter, then pulse again until mixed. Press this mixture firmly into the bottom of your prepared pan. Bake until the crust is golden brown, about 18 minutes, and let it cool slightly while you prepare the filling.
Whisk the Filling
In a medium bowl, whisk the egg yolks until smooth. Then add the sweetened condensed milk, lime zest, lime juice, lemon juice, and a dash of kosher salt. Whisk everything together until fully combined. This filling has a wonderfully tangy flavor that perfectly complements the crust.
Bake the Bar Mixture
Pour the luscious mixture over your cooled crust, then pop it back into the oven. Bake for about 15 minutes, or until the mixture is just set. You want it to hold together but still retain that creamy texture. Let it cool at room temperature before covering and chilling it in the fridge for at least 1-2 hours. This chilling step is crucial, as it helps to firm up the bars, making them slice beautifully.
Chill and Prepare for Serving
Once your lemon key lime pie bars have chilled and set, it’s time to add the finishing touches! In a separate bowl, use an electric mixer to whip the heavy cream until soft peaks form. Gently fold in honey and a splash of vanilla extract, then swirl this whipped cream over the bars.
For a little extra flair, mix lime zest with a pinch of flaky sea salt and sprinkle it atop the bars. Slice them into squares and enjoy a perfectly tart, sweet treat. These bars will keep in the fridge for up to five days, but I bet they won't last that long!
With these easy steps, you’ll have an indulgent treat that’s sure to impress. Happy baking!
