how to make Easy Lemon Squares

Ingredients:

2 cups all-purpose flour
½ cup granulated white sugar
1 cup salted butter (or unsalted plus ½ teaspoon coarse salt)
4 large eggs
1 ½ cups granulated white sugar
¼ cup lemon juice (freshly squeezed from 2 or 3 lemons)
1 ½ tablespoons lemon zest (zest of 2 lemons)
3 tablespoons all-purpose flour

Directions:

Preheat your oven to 350°F. Line the insides of a 9×13-inch glass baking pan with parchment paper. Leave enough overhang to lift the dessert out later; this makes cutting easier. Set aside.
In a large mixing bowl, add the soft butter and sugar. Use a pastry cutter or fork to mix them together until combined. Then, add in the flour and mix again to create a thick dough.
Press the dough firmly into the prepared pan, making sure it’s an even layer. Bake for 15-20 minutes until the edges are lightly browned and the crust feels firm to the touch.
While the crust is baking, prepare the filling. In a separate bowl, whisk the eggs until smooth. Add the sugar, lemon juice, and lemon zest, mixing until everything is well combined. Sift in the 3 tablespoons of flour; sifting is important to avoid flour clumps in your filling.
Once the crust is out of the oven, take a fork and prick holes randomly across the top of the warm crust. Be careful not to poke all the way through! This helps the lemon filling stick to the crust.
Pour the lemon filling into the warm crust. Bake for 20-25 minutes or until the filling is set and no longer jiggles.
Let the dessert cool at room temperature for 2 hours. After that, chill in the fridge for 2 hours before you cut the squares. This cooling time allows the filling to set properly.
Once cool, lift the dessert out of the pan using the parchment paper. Dust the top with powdered sugar, then cut into squares for serving.
You can cover and store leftover lemon squares in the refrigerator for up to 1 week.

FAQs

1. Can I use bottled lemon juice instead of fresh?
Using fresh lemon juice will give you the best flavor, but if bottled is all you have, it can work in a pinch.

2. Can I make these ahead of time?
Yes! Easy Lemon Squares can be made a day or two in advance. Just store them in the refrigerator until you’re ready to serve.

3. What can I do if my filling doesn’t set?
If the filling doesn’t set, it might need a little more time in the oven. Make sure to bake until it is no longer jiggly, as it will firm up more when cooled.
