2 cups old-fashioned rolled oats
1/4 cup plus 2 tablespoons all-purpose flour
2 teaspoons salt
1 teaspoon freshly ground black pepper
1/2 teaspoon chopped rosemary leaves
3/4 teaspoon baking powder
1/2 stick (1/4 cup) cold unsalted butter, cut into bits
1/4 cup plus 2 tablespoons milkPreheat oven to 375 degrees F.
Put the oats into a food processor and pulse until finely chopped. Add flour, salt, pepper, rosemary, baking powder, and butter and pulse until mixture resembles coarse meal. Add milk and pulse until a dough forms about 15 seconds. On a lightly floured surface, roll out dough to 1/8-inch thick (about a 13-inch round) and cut out about 60 square oatcakes. Arrange oatcakes on baking sheets 1-inch apart and bake in middle of oven 12 to 15 minutes, or until lightly brown on the bottom. Transfer oatcakes to a rack and cool completely.
