Swedish Butter Cookies

Swedish butter cookies are the slice-and-bake shortbread you make once and put on permanent rotation. The dough is just butter, powdered sugar, flour, vanilla, and a whisper of baking powder. No eggs, no fuss, no fancy equipment.

The move that elevates these from plain shortbread is the browned butter frosting on top. Cooking the butter until the milk solids turn deep amber adds a nutty, almost caramel flavor that you cannot fake with anything else. Watch the pan closely. Browned butter goes from gold to burnt in seconds, and the difference in flavor is night and day.

Chilling the dough into logs before slicing keeps the cookies tidy. Cold dough cuts cleanly into rounds that bake evenly without spreading. Skip the chill and you end up with puffy, irregular discs.

The directions warn the cookies go from brown to burned fast, and they are not exaggerating. Pull them when the edges are just barely golden. They will firm up on the sheet as they cool.

Pro Tips

• Roll the dough logs in parchment, then in a paper towel tube, before chilling. The tube keeps the bottom from flattening so every slice comes out a perfect circle.
• Use European-style butter (higher fat) if you can get it. The flavor difference shows up loud in a cookie this simple.
• Frost only after the cookies have completely cooled. Warm cookies turn the frosting into a runny glaze instead of a tacky cap.

Variations

• Add 1 teaspoon almond extract or the seeds from half a vanilla bean for a richer flavor.
• Press a single toasted almond or pearl sugar onto each cookie before baking instead of frosting.
• Drizzle with melted dark chocolate instead of the browned butter frosting.
