When I was a kid, if my father wanted to speak disparagingly of someone, he called them a "crumb bum."

This was somewhat confusing for me, a small child, because on Sundays after church, we often went to the bakery where he would purchase an entire box of "crumb bums" and eat them, slathered with butter, much to my mother's chagrin.My mother, "The World's Greatest Cook," hated butter and used it sparingly, if at all.In regard to the great butter debate, I took after my father; nothing beats butter.I eventually figured out that the "crumb bums" and "crumb buns" are not the same; neither are shortening and butter.This week I'm sharing my mother's recipe for Crumb Cake, but I've made two changes. I substituted dark brown sugar for light brown sugar, because that's what was in the house; and butter for shortening, because ... well ... it's butter! I'm also tweaking the name, in honor of my dad.Crumb Bum Cake15-18 servings2 and one-half cups dark (or light) brown sugar1 cup butter, softened3 cups flourOne-quarter teaspoon salt2 eggs1 cup milk1 teaspoon vanilla3 teaspoons baking powder1 teaspoon cinnamonPreheat oven to 375 degrees F.
