The Recipe: Key Lime Shortbread Bars
Ingredients:
For the Shortbread Crust:
- 1 cup (2 sticks) unsalted butter, softened
- 1/2 cup granulated sugar
- 2 cups all-purpose flour
- A pinch of salt
For the Key Lime Filling:
- 4 large eggs
- 1 cup granulated sugar
- 1/2 cup key lime juice (freshly squeezed or bottled)
- 2 tablespoons all-purpose flour
- 1 teaspoon key lime zest (from about 4-5 key limes)
Directions:
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line the 9×9-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
- Prepare the Shortbread Crust: In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. Gradually add the flour and a pinch of salt, mixing until the dough comes together. Press the shortbread dough evenly into the bottom of the prepared pan.
- Bake the Crust: Bake the shortbread crust in the preheated oven for 15-20 minutes or until it turns light golden brown. Remove it from the oven and let it cool slightly.
- Prepare the Key Lime Filling: In another mixing bowl, whisk together the eggs, granulated sugar, key lime juice, all-purpose flour, and key lime zest until well combined.
- Bake the Bars: Pour the key lime filling over the partially baked shortbread crust. Return the pan to the oven and bake for 20-25 minutes or until the filling is set and the edges are lightly golden.
- Cool and Slice: Allow the bars to cool in the pan, then refrigerate for a few hours or until chilled and set. Once set, use the parchment paper overhang to lift the bars out of the pan. Place them on a cutting board and slice into squares or bars.
- Serve and Enjoy: Serve your Key Lime Shortbread Bars chilled, garnished with a sprinkle of powdered sugar or a dollop of whipped cream if desired. The contrast of the sweet topping with the tangy filling is pure bliss!
Recipe Notes
- Fresh vs. Bottled Key Lime Juice: While freshly squeezed key lime juice is preferred for its intense flavor, bottled key lime juice is a convenient alternative and works well in this recipe. Use what’s most convenient for you.
- Storage: Store the bars in an airtight container in the refrigerator. They can be kept for up to a week, although they’re so delicious that they might not last that long! Just make sure to keep them covered to maintain their freshness.
- Key Lime Zest: The zest of key limes adds a burst of citrus flavor. Be sure to zest the limes before juicing them. It’s a simple step that elevates the overall taste.
Frequently Asked Questions
Can I use regular limes instead of key limes?

Can I make these bars in advance?
Yes, these bars can be made a day or two in advance and stored in the refrigerator until you’re ready to serve them. This makes them a perfect dessert to prepare for special occasions, ensuring you have more time to spend with your guests.
Can I freeze Key Lime Shortbread Bars?
Yes, these bars can be frozen for longer storage. Simply wrap them tightly in plastic wrap and aluminum foil, and store them in the freezer. To enjoy them again, thaw them in the refrigerator before serving. This is an excellent option for those times when you want a taste of the tropics in the dead of winter!
Can I add a meringue topping?
If you’d like to add a meringue topping, prepare a simple meringue using egg whites and sugar, spread it over the key lime filling, and bake until lightly browned. This adds an extra layer of sweetness and a beautiful golden finish to your bars.
