Banana Nut Muffins

"These Banana Nut Muffins have a crunchy sugar topping, a nutty pecan interior, and the deliciousness of added chocolate chips, plus the bonus of browned butter. They are packed with flavor and a recipe that you will be making frequently. Using sour cream, yogurt, buttermilk, apple sauce, or in this case, bananas helps to keep your muffins moist. Simple ingredients but with a few items that you may not be used to, like finely ground sea salt or demerara sugar."
