Buttery Jam Diagonals

Consider this an emotional support cookie: reliable and with a sweet disposition. It recalls the nostalgic comfort of jam-filled thumbprint cookies but with a simple reimagining of the shape and a streamlined, less-fussy process. The dough simply gets formed into wide planks and filled with jam before baking and slicing into long, graphic parallelograms. There’s no faster way to churn out a dozen pretty cookies. Stick with thick, concentrated jams, which will hold up better during baking (look for the word “spread” on the label). Thinner preserves or jellies are more susceptible to spilling messily over the central dams.
