What is so wonderful about these Tart Lemon Bars? The secret is the cookie crust. Fresh lemon zest is added to the buttery crust and then topped with a tart, tangy lemon filling.

We have a Meyer Lemon Tree, but Meyer lemons are slightly more on the sweet side. If you are using Meyer lemons, you might not get quite the flavor a real lemon lover is going for. The photos in this post are using Meyer lemons.
One day, my son's friend handed me a bag of huge, thick-skinned lemons that were not Meyers. They made fantastic Tart Lemon Bars. If you are not sure what is available in your area, talk to the produce clerk at your local grocery store, and they can help you pick out the best fresh lemons for you.

Step by step with photos
Making the cookie base
In a large mixing bowl, combine the butter or margarine with the flour, powdered sugar, salt, and lemon zest. The butter or margarine works best at room temperature.
You can use a pastry cutter, a fork, your fingers, or do like I do and use an electric mixer. A food processor also works well for this. I prefer the electric mixer because it is quick and easy to clean up.
Mix ingredients for the crust, but do not over mix. Having little bits of butter showing through in the coarse crumbs makes for a better crust.
Press mixture into a 13 x 9-inch glass pan that has been sprayed with non-stick spray. Bake crust in a 350-degree oven for about 20 minutes.
Making the lemon filling
Using the same bowl, you made the crust in, beat the eggs using an electric mixer. After about 30 seconds of mixing, add the granulated sugar, salt, lemon juice, and lemon zest.
After the crust bakes for about 20 minutes, slowly and carefully pour the lemon mixture over the hot crust.
Continue to bake for another 20 - 25 minutes. The Lemon Cookie Bars are done when the center of the filling has set, and the top of the bars are just starting to turn a golden brown color.
As you can see in the photo above, I can't wait for the cookies to cool completely before cutting them. The cut is cleaner when they are cool. However, they are yummy when they are warm too!
Use a sharp knife to cut these cookies. Store these cookies in an airtight container or cover the baking dish with plastic wrap or aluminum foil.

My family loves tart lemon bars and this recipe was a hit! I used salted butter and added a raspberry on top of each square for fun.

Fantastic! Hard to find a tart and tangy recipe but this one is so good. The second time I made them I increased lemon juice to 1cup and 2 full tablespoons of zest as well as reducing sugar to 1cup and increased flour to 1/2 cup. Super tangy just the way we love them. They were gone by the end of the day! Wonderful original recipe

Fantastic! Made once this way and once with half lemon half orange juice and zest! solid recipe! Did find though that I had to bake the crust a little longer than required as it was still pretty blonde after 20 minutes me my family likes a well done crust! (I also used salted butter for the crust but again that is a personal preference.) Thanks for a great recipe!!
Cook This Again, Mom!
Awesome and thank you! Take care.
