The Best Lemon Bars

Lemon bars are a love or hate relationship. You either love them or you don’t. I for one, LOVE lemon bars. Like I am obsessed with them! I am the first to grab a lemon bar at any gathering. They are so dang good with that shortbread crust and that tangy tart lemon center. My hubby, on the other hand, hates lemon bars. So I make them any opportunity that I can to feed a crowd.

You will not find a better lemon bar recipe than this one. I have tried several and these are my requirements. A buttery shortbread crust with enough custardy lemon filling on top. I like the perfect ratio of shortbread with the lemon filling. And these are everything you have ever wanted in a lemon bar! I can even get my lemon hating husband to eat these bars.

How do you make lemon bars?

You start by making the shortbread crust. Then while the crust is baking you make the lemon filling. You pour the filling over the hot crust and continue to bake until set. Once they are cooled, you sprinkle the top with powdered sugar.

How do you cool lemon bars?

Once you remove the lemon bars from the oven, let cool to room temperature for at least two hours.

Do you put lemon bars in the fridge?

You can store lemon bars tightly covered at room temperature or in the fridge. But the flavor of the bars improves with refrigeration.

    OMG!!! Just made these and I can not believe how simple and delicious this recipe is. Lemon bars are my favorite dessert and I have never found a simple recipe I could do on my own. Thank you so much for posting this and I look forward to trying some of your other recipes soon!

  2. I’m sorry. I don’t mean to be rude but, you never mentioned how much this recipe yields. Or does that all depend on the person cooking it. I presume it is the later one, but I just want to be sure. . .

    I reduced the sugar to 1.5 cups and added the zest of one lemon. I also poured the lemon / egg / sugar mixture over the crust while it was still hot and reduced the second baking time to 20 minutes. They came out perfect. I’d been looking for a recipe similar to my grandma’s (no cream cheese, baking powder, melted butter) and this was spot on.

  4. I’m just curious but is there a recipe for the lemon bars that just calls for the lemon pudding and pie filling instead of the zest and lemon juice? Thank you

  5. What would the recipe be if you just used the lemon pudding and pie filling? It would take less time and fewer ingredients. What do you think?

    Oh my, wow! These lemon bars were named “Perfect Lemon Bars” for a reason, they have the perfect amount of lemon flavor. I cut them into small squares. They were gone in an instant!!
