Ingredients

  • 1 1/2 cups all-purpose flour
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 stick unsalted butter, softened
  • 1 cup packed light brown sugar
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 1/2 cup whole blanched almonds (2 1/2 ounces)

Method

  • Whisk together flour, baking soda, and salt. Beat together butter and brown sugar in a large bowl with an electric mixer until pale and fluffy, then beat in egg and vanilla. At low speed, mix in flour mixture until a dough just forms. Stir in whole almonds. Divide dough in half. Using a sheet of plastic wrap or wax paper as an aid, form each piece of dough into a log 9 to 9 1/2 inches long (about 1 1/4 inches in diameter). Chill, wrapped in plastic wrap, until very firm, at least 4 hours. Freeze 30 minutes to facilitate slicing.
  • Preheat oven to 350°F with racks in upper and lower thirds. Line 2 large baking sheets with parchment paper. Cut 1 log of dough crosswise into slices less than 1/8 inch thick with a thin sharp knife, rotating log after each slice to help keep round shape. (If dough gets too soft to slice through nuts easily, freeze briefly.) Arrange cookies about 1/2 inch apart on baking sheets.
  • Bake cookies, switching position of sheets halfway through, until golden brown all over, 12 to 15 minutes total. Transfer cookies on parchment to racks to cool.
  • Repeat with remaining dough (cool baking sheets and line with fresh parchment).
