Serves: 36
  • 2 bottles Guinness stout beer (12 oz. each)
  • ½ cup brown sugar
  • 2¾ cup al-purpose flour
  • ⅓ cup unsweetened cocoa powder
  • 1 tsp. instant espresso powder
  • ¾ tsp. baking soda
  • ½ tsp. salt
  • 1 stick unsalted butter, softened
  • ½ cup shortening
  • 1 cup granulated sugar
  • ½ cup brown sugar
  • 2 eggs
  • 1 tsp. vanilla extract
  • 2 cups white chocolate chunks
  • 1 cup semisweet chocolate chunks
  1. Preheat the oven to 350 degrees. Line baking sheets with parchment paper.
  2. Reduce the beer with ½ cup brown sugar in a medium saucepan over medium-high heat until mixture is syrupy and measures ⅓ cup, 30-45 minutes. Remove syrup from heat; set aside to cool slightly.
  3. Whisk together flour, cocoa, espresso powder, baking soda, and salt in a bowl and set aside.
  4. Cream butter, shortening, granulated sugar, and ½ cup brown sugar in a bowl with a mixer on medium speed until fluffy, about 3 minutes.
  5. Add beer syrup, eggs, and vanilla; mix to combine.
  6. Stir flour-cocoa mixture into creamed mixture until flour is no longer visible. Fold in white and semisweet chocolate chunks until distributed.
  7. Scoop dough (about 2 inch balls) onto prepared baking sheets. Bake cookies until edges are set, 12-14 minutes. Let cookies cool 2 minutes on baking sheets, then transfer to a rack to cool completely.
