Serves: 15
For the Cookies:
  • 6 ounces salted butter
  • 2.5 cups powdered sugar
  • 6 egg whites
  • 2 T vanilla extract
  • 1½ cups all purpose flour
  • Cookie filling, recipe follows
Cookie filling:
  • 4 ounces semisweet chocolate
  • 1 ounce butter
For the cookies
  1. In a small saucepan, melt the butter, and cook, over medium heat, until the butter is fragrant and has taken on a rich nutty brown color. Set aside and cool. Beat the egg whites until frothy, add the powdered sugar, vanilla and brown butter and beat until combined. Add the flour, stir until just mixed, and spoon mixture onto cookie sheets lined with parchment. Bake at 350 degrees 10-11 minutes, or until the edges are golden brown.
For the Filling:
  1. Melt the butter and the chocolate together over low heat until smooth.
To assemble the cookies:
  1. Match up cookies until you have reasonably matching pairs. On one side of each pair, brush a layer of chocolate to edges of cookie. I like to keep the chocolate relatively thin so it doesn't overwhelm the flavor of the brown butter. Sandwich together with pair.
Note: the original Gale Gand recipe can be found here: I will admit that several cookies got eaten in my household before I got around to sandwiching them at all. If you have more self-restraint than we do, you might want to double the filling recipe.
