loaf pan coffee cake recipe

A friend's having a birthday, and I've been thinking about what kind of cake I want to bake for her. The celebration will be only three people, so I want the smallest possible cake. I was thinking a coffee cake might be good, one made in a loaf pan, because that would be small. So I've been researching coffee cake loaf pan recipes and sort of getting overwhelmed the way it's easy to, when researching on the internets.
