A little reason to celebrate

National Lacy Oatmeal Cookie Day

Food ยท March 18

A day for lacy oatmeal cookies, the thin, crisp, see-through cookies made with oats, butter and sugar that spread into delicate rounds as they bake.

National Lacy Oatmeal Cookie Day

National Lacy Oatmeal Cookie Day falls on Thursday, March 18, 2027. That is 142 days away.

Lacy oatmeal cookies are thin, crisp rounds that bake into a web of caramelized sugar and oats. Hold one up to a window and light comes through the holes. They look fragile, and they are.

The dough is simple: butter, sugar, oats and a little flour, often with an egg and a splash of vanilla. With so little flour holding things together, the butter melts and the dough spreads across the pan. The sugar bubbles and browns, leaving tiny gaps behind. The result tastes like toffee with a toasted oat crunch.

Bakers learn quickly to leave plenty of room between spoonfuls, because a tablespoon of dough can spread wide enough to meet its neighbors. Parchment paper helps them release. Many people let the cookies cool on the sheet for a minute or two so they firm up before moving them. While still warm and bendy, they can be draped over a rolling pin for a curved shape or rolled around the handle of a wooden spoon into a tube.

They are often served plain with coffee or tea. Some bakers drizzle them with melted chocolate or press two together with a thin layer of chocolate in between. They also make a crunchy topping for a bowl of ice cream.

Humidity is their weak spot. Left out on a damp day they soften and turn chewy, so they keep best in a tightly closed tin, with sheets of paper between the layers.
