Chocolate Stout Cake

—
1. Preheat oven to 180°C
2. Grease a 12-cup capacity Bundt pan and dust with the cocoa powder, tapping out the excess.
3. In a medium bowl, whisk together the flour, cocoa, baking soda, and salt.
4. In a small pot, combine the butter and stout. Stir over medium heat, until the butter is melted. Remove from heat, add 200g of the chocolate, and whisk until smooth. Set aside to cool slightly.
5. Using an electric mixer (a stand mixer is best if you have one), beat the eggs and sugars on medium-high until light and fluffy. Beat in the chocolate mixture and sour cream.
6. Fold in the flour mixture until just combined.
7. Pour into the prepared pan and bake until a toothpick inserted in the center comes out with a few moist crumbs attached, about 50min.
8. Allow to cool for 15min in the pan then turn out onto a cooling rack.
9. In a small pot, bring the cream just to a boil. Remove from heat, add the remaining chocolate, and stand for 5 minutes. Whisk until smooth.
10. Place the cake on the cooling rack over a tray and slowly drizzle the chocolate mixture over the cake. (You can collect the excess and make repeat applications if you like).
11. Allow to set, then serve!
