Rich Guinness Cake - cooking recipe

Ingredients

2/3 cup stout beer, such as Guinness
10 tablespoons unsalted butter (1 stick plus 2 Tbs.)
1/2 cup cocoa powder
1 1/3 cups all-purpose flour
1 1/3 cups sugar
1 teaspoon baking soda
1/2 teaspoon salt
1 large egg
1 large egg yolk
2/3 cup sour cream

Preparation

Preheat oven to 350\u00b0F Butter 8-inch round cake pan. Line with parchment or wax paper. Butter paper.
Bring stout and butter to a simmer in heavy saucepan over medium heat. Add cocoa; whisk until smooth. Cool slightly.
Whisk flour, sugar, baking soda and salt in large bowl to blend; set aside.
Beat egg, yolk and sour cream with electric mixer in another large bowl to blend. Add stout-chocolate mixture to egg mixture, and beat just to combine.
Add flour mixture and beat 30 seconds on slowest speed. Fold batter using rubber spatula until completely combined; pour into prepared pan.
Bake about 50 to 55 minutes, or until tester inserted into center of cake comes out clean. Transfer to rack; cool.
Once it is cool, prepare syrup (can use my recipe of Guinness syrup). Cut a piece of the cake, put in a glass, add some ice cream and drizzle the warm syrup on top. Enjoy!
