Looking for Snack Cake Recipes

Cspittel writes: "I'm looking for snack cake recipes -- made in a single 9x9 (or 8x8) square pan with some sort of simple topping or frosting. Just something simple, not overly sweet and meant to be served out of the pan. Similar to gingerbread or streusel coffee cake. With only 3 of us at home now a big cake either goes to waste or I end up eating it - which is a bad thing!" Please post your recipe today.
