Lemon Bars With Shortbread Crust

Butter: Provides the rich, creamy base for the shortbread crust.

All-purpose flour: Used in both the crust and the filling to give structure.

Powdered sugar: Adds sweetness to the crust and is used for dusting the finished bars.

Granulated sugar: Sweetens the lemon filling.

Eggs: Helps to set the lemon filling and adds richness.

Lemon juice: Gives the bars their signature tangy flavor.

When preparing the shortbread crust, ensure that the butter is fully softened to room temperature. This will help it blend more smoothly with the flour and powdered sugar, resulting in a more cohesive and tender base. Additionally, when pressing the mixture into the baking pan, use a flat-bottomed glass or measuring cup to evenly distribute and compact the crust, which will help it bake more uniformly.

• Allow the lemon bars to cool completely at room temperature. This ensures the shortbread crust and lemon filling set properly before storing.

• Once cooled, cut the lemon bars into desired sizes. Use a sharp knife for clean cuts and wipe the blade between slices to maintain neat edges.

• For short-term storage, place the lemon bars in an airtight container. Layer them with parchment paper to prevent sticking. Store at room temperature for up to 2 days or refrigerate for up to a week.

• To freeze, arrange the lemon bars in a single layer on a baking sheet lined with parchment paper. Freeze until solid, about 2 hours.

• Once frozen, transfer the lemon bars to a freezer-safe container or zip-top bag. Layer with parchment paper to avoid sticking. Label with the date and store in the freezer for up to 3 months.

• When ready to enjoy, thaw the lemon bars in the refrigerator overnight or at room temperature for a few hours. Dust with powdered sugar just before serving for a fresh, delightful finish.

• Preheat your oven to 300°F (150°C). Place the lemon bars on a baking sheet and cover them loosely with aluminum foil to prevent them from drying out. Heat for about 10-15 minutes or until they are warmed through.

• If you prefer using a microwave, place the lemon bars on a microwave-safe plate. Heat on medium power for 20-30 seconds. Check the temperature and continue heating in 10-second intervals if needed. Be cautious not to overheat, as the shortbread crust can become soggy.

• For a quick stovetop method, use a non-stick skillet over low heat. Place the lemon bars in the skillet and cover with a lid. Heat for about 5 minutes, checking frequently to ensure they are warming evenly without burning the crust.

• If you have an air fryer, preheat it to 300°F (150°C). Place the lemon bars in the air fryer basket and heat for 5-7 minutes. This method helps maintain the crispiness of the shortbread crust while warming the lemon filling.

• For those who enjoy a slightly chilled treat, you can also enjoy lemon bars straight from the refrigerator. Simply let them sit at room temperature for about 10-15 minutes to take the chill off before indulging.

• Oven: Used to bake the shortbread crust and the lemon filling at a consistent temperature of 350°F (175°C).

• Mixing bowl: Essential for combining ingredients like butter, flour, and powdered sugar for the crust, as well as granulated sugar, flour, eggs, and lemon juice for the filling.

• Electric mixer: Helps to mix the butter, flour, and powdered sugar until well combined, ensuring a smooth and even crust.

• Whisk: Used to whisk together granulated sugar, flour, eggs, and lemon juice until smooth for the filling.

• 9x13 inch baking pan: The pan where the crust is pressed into and the lemon mixture is poured over, providing the shape and structure for the lemon bars.

• Spatula: Useful for pressing the crust mixture evenly into the baking pan.

• Measuring cups: Necessary for accurately measuring ingredients like flour, powdered sugar, granulated sugar, and lemon juice.

• Measuring spoons: Useful for precise measurement of smaller quantities, such as the ¼ cup of flour for the filling.

• Cooling rack: Allows the lemon bars to cool completely before cutting, ensuring they set properly.

• Knife: Used to cut the cooled lemon bars into individual servings.
