Lemon Squares are a classic dessert that’s loved by many for their perfect combination of sweet and tangy flavors. The creamy lemon filling melts in your mouth while the shortbread crust provides a delightful buttery crunch.
Dusting the bars with powdered sugar not only makes them look stunning but also adds a touch of sweetness that balances the citrusy zest.
Ingredients You'll Need
- All-Purpose Flour- Serves as the foundation of the buttery shortbread crust, providing structure and a firm base for the tangy lemon filling.
- Unsalted Butter- Adds richness to the crust, helping it bind together and bake into a crumbly, melt-in-your-mouth texture.
- Granulated Sugar- Sweetens both the crust and the lemon filling, balancing the tartness of the lemon and creating a perfectly sweet dessert.
- Eggs- Act as the primary binding agent in the lemon filling, giving it a rich, creamy, and custard-like consistency that sets beautifully when baked.
- Fresh Lemon Juice- The key flavor driver, offering a bold and tangy citrus flavor that defines the dessert's refreshing profile.
- Lemon Zest- Amplifies the citrus aroma and flavor, adding depth and a fragrant boost to the filling.
- Powdered Sugar- Used as a finishing touch, it provides a light, sweet dusting that enhances the appearance and adds a touch of elegance.
- Prepare the Shortbread Crust. Preheat your oven to 350°F and grease an 8x8-inch baking pan. Line it with parchment paper for easy removal. In a medium bowl, mix the flour, softened butter, and granulated sugar until crumbly. Press the mixture evenly into the bottom of the prepared pan. Bake the crust for 15-18 minutes or until lightly golden. Let it cool while you prepare the filling.
- Make the Lemon Filling. In a large bowl, whisk the eggs, granulated sugar, lemon juice, and lemon zest until well combined. Sift in the flour and mix until smooth. This will ensure the filling sets beautifully.
- Assemble and Bake. Pour the lemon filling over the cooled crust, spreading it evenly. Bake for 20-25 minutes or until the filling is set and no longer jiggles in the center. Let the bars cool completely before removing them from the pan.
- Garnish and Serve. Dust the cooled lemon squares generously with powdered sugar for a stunning finish. Slice into squares and serve. Enjoy their zesty, sweet perfection!
Tips And Tricks
To create the best lemon squares with a buttery crust and tangy filling, follow these tried-and-true tips and tricks:
- Use Fresh Lemons. Freshly squeezed lemon juice and zest make all the difference in flavor.
- Don’t Skip the Parchment Paper. It makes removing the bars from the pan much easier and keeps them intact.
- Chill Before Cutting. Allow the bars to cool completely in the fridge for cleaner slices.
- Sift Your Powdered Sugar. This ensures an even and smooth dusting on top.
Variations
Lemon squares are a classic dessert, but you can add your own creative twist to customize the flavor and texture. Here are some delicious variations to try:
- Berry- Add a handful of fresh raspberries or blueberries to the lemon filling before baking for a fruity twist.
- Coconut- Mix shredded coconut into the crust for an extra layer of flavor and texture.
- Gluten-Free- Use a gluten-free flour blend in place of the all-purpose flour for a gluten-free version.
- Lavender- Infuse the filling with a touch of dried culinary lavender for a floral twist.
Lemon squares are a delightful dessert on their own, but pairing them with complementary sides or beverages can elevate the experience. Here are some great options to serve alongside:
- Fresh Fruit- Strawberries, raspberries, or blackberries complement the citrus flavor.
- Whipped Cream- A dollop of whipped cream adds a light, airy touch.
- Coffee or Tea- Pair with a hot cup of coffee or herbal tea for a cozy treat.
How Long Do They Last?
Lemon Squares can be stored in an airtight container in the refrigerator for up to 5 days.
They’re best served chilled but can also be enjoyed at room temperature.
Can You Freeze Them?
You can also freeze them for up to 2 months—just wrap them tightly in plastic wrap and place them in a freezer-safe bag.
Thaw your lemon bars in the fridge overnight before serving.
