  • 1 tsp vanilla extract

Instructions

  1. Grease two 9-inch cake pans with shortening. Place parchment rounds in the bottom. Grease the parchment and pan sides, then flour the pans and tap out excess. Set aside.
  2. Preheat oven to 350°F.
  3. Melt 1 cup salted butter in a medium pot over medium-high heat.
  4. Turn heat down to medium and cook, stirring, until the butter browns.
  5. Pour the browned butter into a large bowl. Whisk in the Guinness.
  6. Add sugars and cocoa powder. Whisk until smooth.
  7. Add eggs, sour cream, and vanilla extract. Whisk until combined.
  8. Add flour, baking soda, espresso powder, and salt. Whisk until the batter is smooth.
  9. Divide batter between the prepared pans.
  10. Bake for 17–24 minutes, or until a toothpick in the center has moist crumbs.
  11. Let cakes cool in the pans for 10 minutes, then invert onto cooling racks.
  12. Make the frosting by melting 1 and 1/4 cup salted butter and browning it.
  13. Chill the browned butter slightly before mixing it with cream cheese.
  14. Beat cream cheese until creamy, then add cooled brown butter.
  15. Add powdered sugar gradually until desired consistency is reached.
  16. Mix in Guinness and vanilla extract last.
  17. Assemble the cake by layering and frosting as desired.
  18. Refrigerate if frosting is soft before serving.
