These muffins were born of a special request. A friend asked if I could make banana Oreo muffins and I thought, oh definitely! Based off my banana bread recipe with my now favorite muffin method, the base banana muffin is wonderful. I liked the golden Oreo version the best but the regular was good too. If you want it less sweet, you can just sprinkle with crumbs before baking as I did for the extra batter testers. (I divided my batter in half by weight to make six of each flavor.)
