These muffins are great grabbed straight out of the oven, warm with vanilla ice cream or with a steaming cup of coffee for breakfast. The addition of sour cream makes these muffins super moist, with a awesome rich flavor. This recipe makes two dozen muffins, which is a great because you can share with friends! Use your favorite apples, this recipe used Northern Spy. Honey Crisp are one of my favorite apples, along with Gala and Fuji. A tart apple would do well here too.
