How to make these easy lemon bars
Step One: Make the crust
To make these lemon bars, first start by making the shortbread crust.
You want to combine in your metal mixing bowl, your correctly measured flour, granulated white sugar, and softened butter.
Pro Tip: If you forgot to take your butter out ahead of time, then here are 3 ways to soften your butter. I used my pastry blender to work the butter into the flour and sugar. You could also just use your hands. Don’t be afraid. Get in there.
Then go ahead and press the mixture into a greased 9×13 pan. I made one batch in a 8×11 pan, which you can do if you want a thicker bar. I preferred the 9×13. But hey, you want thick. Go thick. You want thinner. Go 9×13. You’re the boss in your own kitchen.
Pro Tip: Use the bottom of your dry measuring cup to press the mixture into your pan.
Step Two: Make The Filling
Now while these bake for about 20 minutes, go ahead and use the SAME bowl to make the lemon part.
In the same bowl, you need to add some white sugar, flour, 4 room temperature eggs, and of course your lemon juice.
Now here is what I don’t like about most lemon bar recipes out there. They say vague things like “juice of 3 lemons”. Um, I don’t know about you but I don’t always get the same amount of juice from my lemons every time. So frustrating.
So when I tested this recipe I used a glass measuring cup to make sure that I give you an exact amount. I wanted mine nice and tangy so I used 2/3 cup of fresh lemon juice. Which, was usually about 3 lemons (sometimes 2 1/2, sometimes 4). See what I mean? Not always the same.
I also threw in some lemon zest for a real lemon punch. If you want a less tangy lemon bar, you can leave out the zest. Not me. And that’s it.
Give it a whisk (have I told you about my new favorite kitchen tool, this whisk?). And you’re all set. Once your crust has baked, time to pour the lemon filling over it. Be sure to pour the lemon mixture over your crust while it’s still hot. And then bake for another 20 minutes. That’s it!
Oh wait. You need some powdered sugar on top of course. I used a sifter to sprinkle some powdered sugar right on top. Be sure to do this while the bars are warm, so the sugar sticks.
And here comes the hard part. Letting the bars rest and set up in the fridge for about 2 hours. I told you it was the hard part. But then it’s time to cut, eat, enjoy, repeat.
- Make sure to measure your lemon juice. Not every lemon gives the same amount of juice. To be on the safe side I’d buy 4 at the store. Sometimes it only takes 3 but I like having an extra just in case.
- Make sure to measure your flour accurately by scooping with a spoon and leveling with a knife. For a complete tutorial, read this post.
- You need to make sure you are using softened butter for the shortbread crust so it’s incorporated easily.. Here are 3 ways to soften your butter quickly.
- When the crust is done, you want to pour the filling over it immediately. This kind of makes like one beautiful crust to lemon layer.
- Dust the bars with powdered sugar when the bars are warm so the sugar sticks. I like to dust them twice. The first time the sugar sort of melts in, and the second time creates a beautiful layer of powdered sugar on top.
Yes you should! Because they are technically a custard, they should be kept in the refrigerator unless you are serving them right away. They can stay out for a few hours at room temperature if you are serving them at a party, though. After that however, store them covered in the fridge!
These will last about 4 days in the refrigerator. Just be sure to keep them well covered. If they last you that long that is!
Lemon bars can be frozen for up to 3 months. Thaw at room temperature before serving.
