Lemon Squares
Delicious lemon squares made with fresh lemon juice and a light buttercream frosting.
Ingredients
Crust
- 2 cups all purpose flour
- ¾ cup chilled unsalted butter, cut into cubes (not too small)
- ½ cup icing (confectioner's) sugar*
- ½ teaspoon salt
Lemon filling
- 1 cup white sugar
- 3 tablespoons all purpose flour
- ½ teaspoon baking powder
- ⅓ cup fresh lemon juice
- 3 eggs
- 2 teaspoons grated lemon zest
- Icing sugar to dust (optional)
Instructions
- Preheat oven to 350°F (180°C).
- Line a 9 x 12 baking pan with parchment so it overlaps the edges of the baking pan and grease the bottom lightly with butter.
- Prepare the crust by putting the flour, icing sugar and salt into a medium bowl.
- Cut the cold butter cubes into the mixture by using either 2 knives or a pastry blender until you have a coarse crumb-like mixture. Make sure that there are still small pieces of cold butter throughout as this is what keeps the crust tender and flaky.
- Press the crumb mixture into the bottom of the parchment-lined pan.
- Bake at 350°F (180°C) for approximately 20 minutes until lightly golden.
- Remove from oven and set aside (keep oven on).
- Make the lemon filling by placing all the ingredients into a food processor or blender and mixing well.
- Pour the ingredients over the hot crust and place back into oven for an additional 20 minutes.
- Remove from oven and let cool completely. Once cooled, lift the lemon bar out of the pan by using the parchment paper.
- Cut into squares and dust with icing sugar (optional).
Enjoy!
Tips
* If you don't have icing sugar, you can make your own by combining regular white sugar and cornstarch and blitzing it into a fine powder (1 cup sugar and 1 tablespoon cornstarch). Use a high-power blender such as the Nutri-Bullet or it will be grainy.
You can also grate frozen butter using the large holes of a cheese grater — easiest method!
