Discover the timeless delight of old-fashioned lemon squares with our easy-to-follow recipe. These lemon bars are perfectly tangy and sweet with a homemade butter crust and lemon filling. Powdered sugar is added to the top after baking. Perfect for a light dessert.
Gradually add the flour to the bowl with the butter and sugar.
Overlap a piece of parchment paper into a 8x8-inch baking pan.
Press the crust mixture into the baking pan.
Bake at 350-degrees for 15 minutes, or until the edges are lightly browned. Take out of the oven and set aside.
Lemon Filling
In a small bowl, mix the sugar, eggs, lemon juice, flour, and baking powder.
Pour the lemon filling on the top of the crust.
Bake for another 12 minutes.
Topping
After 12 minutes, take them out of the oven. Let them cool down. The lemon filling will be slightly set but not completely firm and will be lightly browned on the top.
After they are cooled, sprinkle confectioners' sugar on the top.
Place in the refrigerator for about 20 minutes before serving. The lemon filling will thicken as it cools.
Notes
If you have leftover lemon bars, they can be put into the freezer.
This recipe cuts the lemon bars into 9 squares, but you can cut them smaller than that.
If you have the time, squeezing your own fresh lemons brings out the best lemon flavor in lemon bars. Using 100% lemon juice from the bottle is definitely more convenient and works great too.
