These are moist, dark, and delicious muffins from the King Arthur Flour Company. They keep well, are made of 1/2 whole wheat flour, and have brown sugar sprinkled on top for a crunchy texture. If you don't have buttermilk, you can use regular milk + 1 tbsp. of lemon juice or white vinegar. The recipe says it makes 12 muffins, but I usually get about 18. It's a very adaptable recipe and also works well with applesauce and oil rather than butter. You can also throw in 1/4 cup of walnuts, if you like.
