Ingredients

  • 6 ounces unsalted butter (1 1/2 sticks; 170g), fluid and warm—roughly 105°F (41°C)
  • 1 tablespoon (15ml) vanilla extract
  • 1 large egg, cold (about 50g)
  • 7 ounces light brown sugar (3/4 cup, gently packed; 200g)
  • 7 ounces white sugar (1 cup; 200g)
  • 2 teaspoons Diamond Crystal kosher salt; half as much by volume if using table salt (7g of either kosher or table salt by weight)
  • 1 teaspoon (3g) ground cinnamon
  • 1/2 teaspoon (3g) baking soda
  • 7 ounces old-fashioned rolled oats—not quick-cooking or instant (2 cups; 200g)
  • 6 ounces all-purpose flour, not unbleached (1 1/4 cups; 170g)
  • 7 ounces dried cranberries or cherries (1 1/4 cups; 200g)

Instructions

  1. Adjust oven rack to middle position, preheat to 350°F (180°C), and line 2 rimmed baking sheets with parchment (not wax paper).

  2. Combine butter, vanilla, egg, brown sugar, white sugar, kosher salt, cinnamon, and baking soda in a medium bowl. Stir until no lumps remain, then fold in rolled oats, followed by the flour and dried cranberries or cherries. Divide into 30 one-ounce portions with a roughly 2-tablespoon scoop and arrange on prepared baking sheets. Let stand at room temperature for at least 25 minutes, no more than 75 minutes.

  3. Bake until pale gold around the edges, but still puffed and steamy in the center, about 15 minutes. Cool directly on baking sheets until firm, about 10 minutes. Enjoy warm, or store in an airtight container up to 3 days at room temperature.
