Ingredients

• 250 grams Unsalted butter
• 250 ml Guinness stout
• 75 grams Unsweetened cocoa powder
• 400 grams Granulated sugar
• 100 grams Brown sugar
• 275 grams All-purpose flour
• 1.5 teaspoons Baking soda
• 0.5 teaspoons Salt
• 2 large Eggs
• 150 ml Sour cream
• 2 teaspoons Vanilla extract

Directions

Step 1

Preheat your oven to 180°C (350°F). Grease and line a 9-inch (23 cm) round cake pan with parchment paper.

Step 2

In a medium saucepan over medium heat, combine the butter and Guinness stout. Stir until the butter is completely melted and the mixture is smooth. Remove from heat and allow to cool slightly.

Step 3

Whisk the cocoa powder into the warm butter and Guinness mixture until fully dissolved and smooth. Set aside to cool.

Step 4

In a large mixing bowl, combine the granulated sugar, brown sugar, flour, baking soda, and salt. Mix well to combine.

Step 5

In a separate medium bowl, whisk together the eggs, sour cream, and vanilla extract until smooth.

Step 6

Pour the egg mixture into the dry ingredients and gently mix until just combined. Add the cooled cocoa and Guinness mixture and stir until you have a smooth, lump-free batter.

Step 7

Pour the batter into the prepared cake pan and smooth the top with a spatula.

Step 8

Bake in the preheated oven for about 50-60 minutes, or until a skewer inserted into the center of the cake comes out clean.

Step 9

Remove the cake from the oven and allow it to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Step 10

Serve as is or with a light dusting of powdered sugar. For an extra touch, pair it with whipped cream or cream cheese frosting.
