Best Classic Lemon Bar Recipe

Last updated on December 16th, 2021

When it comes crafting the best tasting classic lemon bar recipe – you just have to keep it simple and easy. Cookie crust. Soft lemon bar filling. Doesn’t get much better than that.

It’s odd, posting a baking recipe in the middle of summer, but this summer has been one for the record books, as far as the weather goes. While good friends up in the pacific northwest are sweltering under triple-degree temperatures, we here in the southwestern United States are having a relatively mild summer. We’ve seen temperatures in Albuquerque dip as low as 68 degrees accompanied by rain… during the summer…

But enough about the weather, onto the tips!

This recipe is based on a classic one and doesn’t really call for substitution unless you’re going to do a 1:1 ratio of a different type of flour for the all-purpose flour. You can also do a 1:1 ratio of an artificial sweetener for the sugar.

As always when it comes to cooking with me – we’re going to start by gathering up all of the ingredients together (they’re listed below, there’s a jump to recipe button for that list).
