Pairing beer with cake: Chocolate Stout Cake

I want to try baking this chocolate cake with the Sam Adams - Chocolate Bock beer .. and then serve it with glasses of the same brew :)
And maybe add a scoop of vanilla ice-cream into the beer glasses .. A perfect harmony of favorite foods - Cake, Ice-cream and Beer!
