question: What is a good beer pairing for Chocolate cake?
answer: A great choice for Chocolate cake is Libertine Porter (Dry-Hopped Aggressive Porter.). Here's the recipe:
  An avalanche of cross-continental hop varieties give this porter a complex spicy, resinous and citrusy aroma, with a huge malt bill providing a complex roasty counterpoint. Digging deeper into the flavour draws out cinder toffee, bitter chocolate and hints of woodsmoke.
