How to Make It
Preheat oven to 350°F.
To prepare cookies, spread oats onto a jelly-roll pan. Bake at 350°F for 10 to 12 minutes or until lightly browned, stirring every 3 minutes. Remove from oven (do not turn oven off); cool slightly.
Place oats in a mini or full-sized food processor; pulse 5 times or until finely chopped but not ground. Place oats in a large bowl. Weigh or lightly spoon flour into dry measuring cups; level with a knife. Add flour and next 4 ingredients (through baking soda) to oats, stirring with a whisk.
Place oil, butter, brown sugar, and molasses in a large bowl; beat with a mixer at medium speed until well blended (3 minutes). Add 2 teaspoons vanilla and 1 egg; beat until well combined. Beat in oats mixture at low speed.
Spoon dough by scant tablespoonfuls, 2 inches apart, onto baking sheets lined with parchment paper to yield 40 cookies. Bake at 350°F for 9 minutes or until puffed and just set. (Do not overbake or cookies will get too hard.) Cool on pans 2 minutes; cool completely on a wire rack.
To prepare filling, combine granulated sugar, corn syrup, 3 tablespoons water, and 1/8 teaspoon salt in a small saucepan over medium-high heat; bring to a boil, stirring just until sugar dissolves. Cook, without stirring, until a candy thermometer registers 240°F. Place cream of tartar and egg whites in a large bowl; beat with a mixer at high speed until soft peaks form. Gradually pour hot sugar syrup into egg white mixture, beating first at medium speed and then at high speed; beat in 1/2 teaspoon vanilla. Beat at high speed 5 minutes or until mixture is the texture of marshmallow fluff. Spoon about 1 tablespoon filling onto flat side of each of 20 cookies; top each with 1 cookie.
