Battle of the Cream Filled Buns (слэш)

When a new bakery opens up in Godric's Hollow, Harry is initially over the moon. Unfortunately the prickly nature of the owner soon turns Harry sour and he decides to teach the man a lesson by beating him at his own game. It's only baking cakes after all, how hard can it be?
Join Harry and Severus as their rivalry causes sparks, and cakes, to fly. Will the heat between them cause things to rise to perfection or burn to a crisp? Who knows, but there will be plenty of cake based puns as we find out.
