Sandtortchen (Sand Tarts)

Sand tarts are a German Christmas tradition that dates back centuries, and the name tells you exactly what to expect: a sandy, crumbly, butter-rich cookie that shatters with the first bite. The dough is dead simple (butter, sugar, eggs, flour) but the technique is what makes them special.

Rolling the dough as thin as possible is the whole point. Paper-thin means crispy, and crispy means these cookies have the right snap. An overnight chill firms the butter-heavy dough enough to roll without sticking, though you’ll still want a well-floured board. Work with a quarter of the dough at a time and keep the rest cold.

Each diamond-shaped cookie gets brushed with beaten egg white (which gives them a glossy finish), then a sprinkle of sugar and cinnamon, and a pecan half pressed into the center. They bake fast, just 8 to 10 minutes until the edges barely turn golden.

Pro Tips

• Chill the dough overnight, not just for an hour. Warm dough is impossible to roll thin and sticks to everything.
• Roll from the center outward, rotating the dough as you go. This prevents sticking and keeps the thickness even.
• Watch them closely in the oven. At this thinness, they go from done to burnt in under a minute.
• Cool on the sheet for one minute before transferring. They’re too fragile to move immediately.

Variations

• Use blanched almond halves instead of pecans for a more traditional German presentation.
• Add a pinch of nutmeg or cardamom alongside the cinnamon for a more complex spice.
• Cut into rounds or stars instead of diamonds for a different holiday cookie shape.
