"Looking back at our initial notes about Tarn Bakery is like reading the rantings of someone who’s seen the light. “Actually tastes of Guinness”—followed by three exclamation marks—then words like “malty” and “moist”, and an ominous final scrawl of, “I think this is it”. The Guinness cake from this Crouch Hill spot is unlike any of the others on this list. The topping is a combination of sour cream and crème fraîche which gives it a nice tang, there’s a sweet-smoky whiskey caramel drizzle, and, crucially, there’s a double layer of buttercream. It’s intensely Guinnessy, intensely chocolatey, and we have intensely strong feelings about it. " - sinead cranna
