Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
• In a saucepan, combine Guinness and butter. Heat over medium heat until butter is melted. Remove from heat and whisk in cocoa powder and sugar.
• In a separate bowl, whisk eggs. Add eggs to the Guinness mixture and whisk until combined. Add baking soda, baking powder, salt, and flour. Mix until just combined.
• Pour batter into prepared pan and bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
• For the frosting: In a bowl, beat cream cheese, powdered sugar, and vanilla extract until smooth. Frost the cooled cake.
