- ¾ cup unsweetened cocoa powder
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 ½ teaspoons baking soda

- ⅔ cup sour cream
For the Frosting
- 8 ounces cream cheese, softened
- 1 cup powdered sugar
- ½ cup heavy cream
- 1 teaspoon vanilla extract
Directions

Make the Cake
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease and line a 9-inch springform pan with parchment paper.
- Melt Butter and Guinness: In a saucepan, heat the Guinness and butter over medium heat until the butter melts. Remove from heat and whisk in the cocoa powder until smooth. Let cool slightly.
- Mix Dry Ingredients: In a large bowl, combine flour, sugar, baking soda, and salt.
- Combine Wet Ingredients: In a separate bowl, beat the eggs and sour cream until smooth. Gradually add the cooled Guinness mixture and stir until combined.
- Mix the Batter: Pour the wet ingredients into the dry ingredients and mix until a smooth batter forms. Avoid overmixing.
- Bake: Pour the batter into the prepared pan and bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean.
- Cool: Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
Make the Frosting
- Whip the Cream Cheese: In a bowl, beat the cream cheese until smooth. Add the powdered sugar and vanilla extract, mixing until combined.
- Add Whipped Cream: In a separate bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the cream cheese mixture until smooth and fluffy.
- Frost the Cake: Once the cake is completely cool, spread the frosting generously over the top of the cake to resemble the frothy top of a pint of Guinness.
Serve
