This shortbread was sublime. The oats contributed an almost coconutty texture and a lovely toastiness, and the lavender was a delightful, graceful note. We thought they were delicious right out of the oven, but, as the notes say, they were even better the next day: a little sturdier for packing and with a deeper flavor. Next time I will dial down the salt a tad.

Ingredients

  • 1 1/4 cups rolled oats
  • 8 tablespoons (1 stick) butter, softened
  • 1/4 cup sugar
  • 1/2 cup all-purpose flour
  • 1 teaspoon salt (several folks mentioned in their comments that they reduced the amount of salt. i like my shortbreads on the salty side, so take a note of that)
  • 3/4 tablespoon dry lavender flowers

Directions

  1. Preheat the oven to 325° F convection (or 350° F for a regular oven). Toast the oats for about 10 minutes. Let the oats cool completely and then process in a food processor, until powdery.
  2. Beat the butter with sugar until creamy. Stir in the oats, flour, salt, and lavender. Mix on low speed until the dough comes together. Scrape the dough out onto a work surface and pat it into a log 1 1/4 inches in diameter. Wrap up the log in plastic wrap and refrigerate until very firm, about 2 hours.
  3. Preheat the oven to 325°F convection (or 350°F regular bake). Slice the dough into 1/4-inch thick slices and arrange on a baking sheet lined with parchment paper. Prick the top of the shortbreads with a fork. Bake for about 20 minutes, or until golden (somehow, for a lot of cookies in my oven I found 22 minutes to be the magic number). Slide the parchment onto a wire rack and let the shortbreads cool.
  4. The shortbreads can be kept in an airtight container for about a week.
