Coffee cakes are such a nice simple thing to bake and bring to morning meetings, as a hostess gift, etc. Though I have been accused of brown-nosing with my baking, I love the feeling of making people happy with fresh, homemade coffee cake (or muffins or cookies).
Like most simple baked goods, the ingredients are all things that you probably have around. Besides the typical baking staples, (good quality) cocoa powder, buttermilk, lemons and sour cream or plain yogurt are great to have to use in all kinds of things and keep well. My children are convinced that buttermilk that is a little past its "use by" date actually makes better pancakes.
