The Best Lemon Bars Served on a Clear Plate

A friend recently requested my copy of this recipe for Lemon Squares so I thought that a good reason to make some for me too, right? There are many recipes online but this is the one I’ve been using forever; didn’t realize how long forever was until I went to get the cookbook and do this post.

It was a gift to me at Christmas when I was home visiting my family in St. Louis years ago…many, many years ago!

‘The Artist in the Kitchen is a cookbook published in 1977 for the St. Louis Art Museum and put together by the Friends of The St. Louis Art Museum, all recipes are from the personal archives of members and the Museum staff.

I realize that I’ve got two favorites in this book and how easy they are to find; the pages are pretty evident since they are the only two with butter fingerprints and signs of regular use..I need to try something else don’t I?

The Best Lemon Bars with Powdered Sugar

What makes them the best lemon squares (or bars…same thing!)? Well, there are a million variations but this one has always worked so well for me; I think it’s got a bit of extra lemon juice and has been a favorite of friends and family for years so I won’t tempt fate by trying another!

I’ve also revised the recipe a bit in another post if you need a dessert that will serve more people.

If that’s the case, I suggest you make these Lemon Bars for a Crowd; you’ll find the same photos and a similar recipe but I’ve revised that recipe a bit with more filling so  you can stretch this treat to feed more people.

  1. I just sampled the lemon bars thanks to the fabulous baking of my friend Barb Kiebel, and they were the best lemon bars I’ve ever tasted – and I’m a lemon bar fan from way back! Thank Babs!
