Old-fashioned lemon bars are a timeless treat, and with one tweak (nuts), they can be even more delightful.

Classic Lemon Bars
I inherited all of my grandmother’s handwritten recipes – good old-fashioned lemon bars among them. Later, I came across a lemon bar recipe from a major recipe publisher, and lo and behold, the ingredients and ratios were exactly the same! Recently, I came across another published lemon bar recipe from a different source, and it’s exactly the same, too!
I’m not sure where this classic lemon bar recipe originated, but it seems to be the agreed-upon standard perfect lemon bar in the United States.
Old-Fashioned Lemon Bars + Pecans = Perfect Lemon Bars
As much as I love classic lemon bars, I usually find them to be too sweet.
Decreasing the sugar isn’t an option because it serves an important structural purpose.
Enhancing the Crust
Recently I had a lemon bar with nuts, and it was divine. The rich toasted nuts balanced the sweetness of the filling. This made me wonder about incorporating nuts into the typical shortbread crust and leaving the classic filling as is.
I am happy to report that adding nuts to the crust is the ultimate upgrade to the old-fashioned lemon bar – it’s kind of like a pecan sandy. Feel free to substitute walnuts for the pecans if you like.
Perfecting the Filling
Lemon bar filling is a classic for a reason. If that’s what you want, stick with the original filling recipe.
But! Lemon is just one type of citrus. You could replace the lemon juice for an equal amount of lime, grapefruit, or orange juice for the perfect twist on a classic.
