Chocolate and Guinness

To mark St. Patrick's Day, Nigella Lawson offers up, among other dishes, a chocolate Guinness cake "loaded with sugar, chocolate and a cream cheese frosting that recalls the foamy head of a pint" on NPR.

The cake would also work well without frosting. Now if only I actually had a bottle of Guinness somewhere in the house.

Chocolate Guinness Cake
from "Feast" by Nigella Lawson

1 cup Guinness
1 stick plus 2 Tbsp. unsalted butter
3/4 cup unsweetened cocoa
2 cups superfine sugar
3/4 cup sour cream
2 eggs
1 Tbsp. pure vanilla extract
2 cups all-purpose flour
2 1/2 tsp. baking soda

for the topping:

8 ounces cream cheese
1 1/4 cups confectioners' sugar
1/2 cup heavy cream

Preheat the oven to 350 degrees F, and butter and line a 9-inch springform pan.

Pour the Guinness into a large wide saucepan, add the butter - in spoons or slices - and heat until the butter's melted, at which time you should whisk in the cocoa and sugar.

Beat the sour cream with the eggs and vanilla and then pour into the brown, buttery, beery pan and finally whisk in the flour and baking soda.

Pour the cake batter into the greased and lined pan and bake for 45 minutes to an hour. Leave to cool completely in the pan on a cooling rack, as it is quite a damp cake.

When the cake's cold, sit it on a flat platter or cake stand and get on with the frosting. Lightly whip the cream cheese until smooth, sift over the confectioner's sugar and then beat them both together. Or do this in a processor, putting the unsifted confectioners' sugar in first and blitz to remove lumps before adding the cheese.

Add the cream and beat again until it makes a spreadable consistency. Ice the top of the black cake so that it resembles the frothy top of the famous pint. Makes 12 servings.
