What is the ultimate cake choice for coffee?

When your sweet tooth is calling your name, what treat do you turn to? Me, I'm a sucker for toasted Banana Bread with warm butter - just saying it out loud, I can hear the crunch of those special corner pieces edging onto the soft centre. 

A few ideas to get you going.. Carrot cake, Chocolate Mint slice, Lemon Poppy seed cake, Blueberry muffin, Banana cake, Doughnut, Scones and cream, Mud cake, or something else?
