Shortbread Lemon Squares

Buttery shortbread topped with a bright, lemony almost-custard layer—this handwritten Lemon Squares recipe turns a handful of simple ingredients into something worth waiting to cool before cutting.

Recipe Bio

This Lemon Squares recipe was written right on an envelope, with the shortbread crust on one side of a red line and the lemon topping on the other. The crust gets its first trip through the oven while the topping is mixed, then everything goes back in together for a bright, lemony layer over the shortbread base. Let them cool before cutting into squares.
