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, leaving enough overhang to easily lift the dessert out later. Set aside.
In a large mixing bowl, add the softened butter and sugar. Using a pastry cutter or fork, mix them together until combined. Add in the 2 cups of flour and blend again to create a thick dough.
Firmly press the dough into the prepared pan, making sure it forms an even layer. Bake for 15-20 minutes, or until the edges are very lightly browned and feel firm to the touch.
While the crust is baking, prepare the filling. In a separate bowl, whisk the eggs until smooth. Then, add in the 1 ½ cups of sugar, lemon juice, and lemon zest. Mix everything until combined.
Sift in the 3 tablespoons of flour to avoid clumps. This step is important for a smooth filling!
Once the crust is out of the oven, use the tines of a fork to poke holes randomly across the warm crust. Be careful not to poke all the way through; this helps keep the lemon curd filling on top.
Pour the lemon filling into the warm crust. Bake for another 20-25 minutes, or until the filling is set and not jiggly.
Let the dessert cool at room temperature for 2 hours, then chill it in the fridge for 2 more hours before cutting into squares. It’s essential to give it enough time to set.
Once cool, use the parchment paper to lift the dessert from the pan. Dust the top with powdered sugar and cut into squares for serving.
Cover and store any leftover lemon squares in the refrigerator for up to 1 week.

You can add a layer of meringue on top of the lemon filling before baking for a fluffy lemon meringue bar. Alternatively, try using limes instead of lemons for a different citrus flavor!
