Lemon Squares, made from scratch

Growing up, my mother made these for me. While I don't remember Nanny ever making them I've been told that the recipe came from her (or is also made by her). When I was in college my mother would send them to my dorm-mates and me and the obsession was ongoing. I think mom sent them to Raleigh maybe 4 or 5 times one semester and we could never get enough! I've realized that the "cheater" lemon square recipes that use lemon pudding or jello (whatever the cheater recipe is) are so artificial tasting and almost too lemony. These lemon squares are absolutely delightful. The subtle lemon flavor of these squares screams "from scratch" and I love the brownie like consistency.

Lemon Squares

4 eggs, beaten until foamy
2 cups sugar
1 1/3 cups Wesson oil
2 cups flour
1 teaspoon salt
1 small bottle of lemon extract (1 fl oz.)***

Preheat oven to 350 degrees. Grease a 7x13 or 9x13 casserole dish.
Mix ingredients together and pour into greased dish. Bake for 30 minutes.
Dust with confectioner's sugar. Let it cool before slicing into 2 inch squares.

***I have also made this with 1 fresh lemon, the zest and juice, and had good results.
