Preheat the oven to 375 F.
Grease a 12-cup muffin tin.
In a mixing bowl with an electric mixer, cream together butter and sugar. Add the eggs and mix well; stir in
milk.
In another bowl, combine the dry ingredients and blend well. Add the dry mixture to the first mixture; stir to
combine. Gently fold in blueberries.
Fill the greased muffin cups about two-thirds full. Sprinkle tops with some sugar.
Bake for about 20 minutes, or until the tops are lightly browned.
