Almond Shortbread Bars

These almond shortbread bars use one egg in two clever ways. The yolk goes into the dough for color and richness, and the white gets whisked with water into a glaze that paints over the top before the chopped almonds go on. The result is a faint sheen across the surface and almonds that stay locked in place rather than rolling off when you slice the bars.

The dough is the classic three-to-one flour-and-fat ratio that defines real shortbread, scaled up for a jelly-roll pan. Pressing the dough flat into the pan is faster than rolling it, and it bakes evenly across the wider surface so every bar comes out the same thickness.

The almond extract dose stays modest, which is exactly the right call for a base topped with whole nuts. More would push the flavor toward marzipan candy. As written, the proportion keeps the butter flavor in the lead with the almond riding underneath.

Cool fully before slicing. Warm shortbread crumbles instead of cutting clean.

Pro Tips

• Beat the dough on low only until it looks like coarse meal. Overmixing develops gluten and turns the bars tough.
• Press the dough into the pan with the bottom of a measuring cup for an even thickness all the way to the corners.
• Brush the egg-white wash on with a pastry brush in a thin even coat. Pools of wash bake into shiny patches.
• Pull the bars when the edges are pale gold and the top still looks matte. They overbake fast.

Variations

• Swap chopped pecans or sliced almonds for the standard chopped almonds for a different look on top.
• Press a generous spoonful of orange or lemon zest into the dough for a brighter version.
• Drizzle the cooled bars with a thin chocolate stripe for a more dressed-up tray.
