I'll go ahead and save you the google search--a buckle is a type of coffee cake that normally has a struesel topping and fresh fruit in the dough. Or, to give you a better idea, I've started referring to it affectionately as a muffin-cake. I've been on a big blueberry kick lately because I know that summer is waning, and this recipe definitely satisfied my insatiable cravings. Made with cake flour, this buckle recipe is light, fluffy, and moist. It's taken from an Alton Brown recipe (so you know it's good) and is sprinkled with a nutmeg struesel that adds this wonderful spice to the sweet blueberry flavor.
