This basic muffin is not your stir-it-gently, dense, fruit-and-nut-filled health muffin. Instead, it's a beat-it-up, cake-type muffin, high-crowned and very "vanilla-looking." This is a great muffin for anyone who don't want a lot of "stuff" in their muffins. With its basic sugar-cinnamon-nutmeg flavor, it's more reminiscent of a plain doughnut (without the deep-fat frying) than anything else.
As plain as it is (which is just the way some people like things), it's a good candidate for additions of dried fruit and/or nuts to the batter, as well as a garnish of flavorful jam or preserves when serving time rolls around. I just glazed it with basic glaze.
