You want the mixture to be crumby little balls. Sprinkle the mixture into the pan and press it down firmly. Toss in the fridge for 30 minutes.  Now you will cook for 15-20 minutes or until the top is golden brown. Once done, set aside.  I work on the filling while it is air frying. Whisk up the eggs, flour, and sugar in a bowl. Toss in the milk, lemon zest, and lemon juice along with salt. 

Stir until combined and pour into baked crust. Bake another 10-12 minutes. Allow bars to cool, then dust with powdered sugar.

How to zest a lemon? 

To zest a lemon, you will use a zester or grater. Take your washed lemon and run it across the blades. You want to remove only the yellow portion of the skin. 

Avoid the white as that will make your zest very bitter. Carefully work your way all around the lemon. 

If you don’t have either of those tools, a pairing knife works, you need to carefully cut the peel and then slice it up into tiny pieces. 

Can you buy lemon zest? 

Some stores do sell dried lemon zest. While it can save time on prep, you will find it does not provide that crisp fresh citrus flavor you will get from fresh lemon zest. 

How much zest per lemon? 

One medium-sized lemon will roughly provide around 1 tablespoon of lemon zest and 2-3 tablespoons of lemon juice. 

I use this as a good guide to know how many lemons to buy for any lemon recipe I make. 

What’s the point of lemon zest? 

The lemon zest will elevate the flavor of your lemon squares. Giving it that nice punch of citrus in each bite. 

If you don’t want to use lemon zest, replace every 1 teaspoon of zest with 2 teaspoons of lemon juice. 

This will help amp up the lemon flavor without zesting your lemons. 

How do I know when lemon bars are done?

The best guide is a jiggle test. Carefully jiggle the pan slightly, and if you find the bars don’t wiggle, they are done. 

You might find the center of the bars will wiggle just a bit. If yours do, that is okay. 

Allow your bars to sit on a cooling rack to cool as well. That can help the center finish baking and set up as well. 

Storing Lemon Squares

Lemon squares need to be refrigerated if you don’t plan to eat them right away. The lemon bars need to be covered in a container. 

If you prefer eating them at room temperature, take a slice or two and let it warm up for n hour on the counter. 

You never want your lemon bars to sit out for more than 2 hours. Or you run the risk of bacteria growing at a rapid pace. 

Can You Freeze Lemon Bars?

Yes, the key is to let the lemon bars cool to room temperature, before storing them!

How To Freeze Lemon Bars 

Absolutely. Let the bars fully cool. Do not put powdered sugar on bars. Slice and place in an airtight container or bag. Suppose you stack bars and place wax paper between layers to prevent sticking. 

Freeze for 3-4 months. When you want some, remove and thaw on the counter for an hour or do a slow thaw in the fridge overnight. 

If you do freeze it with powdered sugar on top, it will just melt into the squares. It’s ok to do it will create a sticker top to the bars.
