Ingredients

For the Shortbread Crust:

  • 1 1/2 cups all-purpose flour

  • 1/2 cup powdered sugar

  • 1/4 teaspoon salt

  • 1/2 cup unsalted butter (cold and cubed)

For the Lemon Filling:

  • 1 cup granulated sugar

  • 2 tablespoons all-purpose flour

  • 1/2 teaspoon baking powder

  • 1/4 teaspoon salt

  • 3 large eggs

  • 1 tablespoon lemon zest

  • 1/2 cup fresh lemon juice (about 2-3 lemons)

  • Powdered sugar for dusting (optional)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

  1. Make the Shortbread Crust:
    Preheat your oven to 350°F (175°C). Grease a 9×9-inch square baking pan or line it with parchment paper for easy removal of the bars.
    In a medium bowl, whisk together the flour, powdered sugar, and salt. Add the cold, cubed butter to the dry ingredients and use a pastry cutter or your fingers to work the butter into the flour mixture until it forms a crumbly dough.
    Press the dough evenly into the bottom of the prepared baking pan, creating a smooth and even crust. Bake the crust in the preheated oven for 15-20 minutes, or until lightly golden brown. Remove from the oven and set aside to cool slightly.

  2. Make the Lemon Filling:
    While the crust is cooling, prepare the lemon filling. In a medium bowl, whisk together the granulated sugar, flour, baking powder, and salt. Add the eggs, lemon zest, and lemon juice, and whisk until the mixture is smooth and well combined.

  3. Assemble and Bake:
    Pour the lemon filling over the slightly cooled shortbread crust. Return the pan to the oven and bake for an additional 20-25 minutes, or until the filling is set and the top is slightly golden. You can test if the filling is done by inserting a toothpick into the center—it should come out clean when ready.

  4. Cool and Serve:
    Allow the bars to cool completely in the pan on a wire rack. Once cooled, dust the top with powdered sugar (optional) and cut the bars into squares. Serve chilled or at room temperature.

Servings and Timing

  • Servings: 9-12 bars (depending on size)

  • Prep Time: 15 minutes

  • Cook Time: 35-45 minutes

  • Total Time: 1 hour

  • Cooling Time: 30 minutes

Variations

  • Gluten-free version: Substitute the all-purpose flour with a gluten-free flour blend to make these bars gluten-free.

  • Fruit twist: Add a layer of raspberry or blueberry jam on top of the crust before adding the lemon filling for a fruity twist.

  • Lemon meringue bars: For an extra touch, top the lemon filling with a light meringue layer and bake until golden brown.

  • Herb-infused: Add a hint of fresh herbs such as thyme or rosemary to the shortbread crust for a more sophisticated flavor.

Storage/Reheating

  • Storage: Store the lemon bars in an airtight container in the refrigerator for up to 4-5 days. Make sure to separate layers of bars with parchment paper to avoid sticking.

  • Freezing: These lemon bars freeze well! Wrap them individually in plastic wrap and store them in a freezer-safe container for up to 2 months. Thaw at room temperature before serving.

  • Reheating: These bars are best served chilled or at room temperature, so there’s no need to reheat. However, if you prefer them warm, you can briefly microwave them for 10-15 seconds.

FAQs

1. Can I make the shortbread crust ahead of time?

Yes, you can prepare the shortbread crust a day in advance and store it in the refrigerator until you’re ready to bake the lemon filling.

2. How do I prevent the lemon filling from cracking?

Avoid overbaking the lemon bars, as this can cause the filling to crack. Bake until the filling is just set, and let the bars cool slowly at room temperature.

3. Can I use bottled lemon juice?

For the best flavor, fresh lemon juice is recommended. Bottled lemon juice can be used, but it may not have the same fresh, vibrant taste.

4. Can I add more lemon zest for extra flavor?

Yes, feel free to increase the lemon zest to suit your taste. You can add up to 2 tablespoons of lemon zest if you prefer a more pronounced lemon flavor.

5. Can I make this recipe in a larger pan?

Yes, you can double the recipe and bake it in a 9×13-inch pan, but the cooking time may vary. Keep an eye on it and adjust as needed.

6. How do I know when the lemon filling is done?

The lemon filling is done when it is set in the center and slightly golden on top. You can test it with a toothpick—it should come out clean when inserted into the center of the bars.

7. Can I use margarine instead of butter for the crust?

While butter gives the best flavor and texture for the shortbread crust, you can substitute margarine if needed. The texture might be slightly different, but it will still work.

8. Can I make lemon bars with a graham cracker crust?

Yes, you can substitute the shortbread crust with a graham cracker crust for a slightly different texture. Simply press a mixture of graham cracker crumbs, butter, and sugar into the pan and bake it before adding the lemon filling.

9. Can I use a different citrus fruit for the filling?

Yes, you can substitute lemon juice with lime, orange, or grapefruit juice for a different citrus flavor. However, keep in mind that the sweetness and acidity of the fruit may affect the balance of the filling.

10. How can I prevent the crust from being too crumbly?

Ensure that the butter is cold and cubed when making the shortbread crust. This will help create the perfect crumbly texture. If it’s too crumbly after baking, you may need to add a touch more butter next time.

Lemon Bars with Shortbread Crust are the perfect combination of tart, sweet, and buttery goodness, making them a must-try dessert for any lemon lover.
