Guinness Chocolate Cake

Rich, dark, and unapologetically indulgent, this Guinness chocolate cake delivers deep cocoa flavor with a subtle malted finish. Moist and tender, it’s the kind of dessert that feels right at home on a cozy evening or as a showstopper for guests. Topped with a light, creamy frosting reminiscent of a freshly poured stout, this cake balances decadence with restraint.

Ingredients
Cake
  • 1 cup Guinness stout
  • 1 cup (2 sticks) unsalted butter
  • ¾ cup unsweetened cocoa powder
  • 2 cups granulated sugar
  • ¾ cup sour cream

Frosting (optional)
  • 8 ounces cream cheese, softened
  • 1 cup powdered sugar
  • 1 cup heavy cream
Instructions
Preheat oven to 350 degrees. Grease a 9-inch cake or springform pan.
Heat Guinness and butter in a saucepan over medium heat until melted. Whisk in cocoa powder until smooth; cool slightly.
In a large bowl, whisk sugar and sour cream. Add eggs and vanilla, mixing until smooth. Slowly whisk in Guinness mixture.
In a separate bowl, combine flour, baking soda, and salt. Gently fold into wet ingredients.
Pour batter into pan and bake 45–50 minutes, until a toothpick comes out clean. Cool completely.
