1/2 cup butter
2 cups flour (unsifted, blend of bread and pastry)
1 cup sugar
2 teaspoons baking powder
1/2 cup milk
1/2 teaspoon salt
2 1/2 cups blueberries
2 teaspoons sugar (for tops)
1 teaspoon vanilla
Mix the blueberries with some of the flour before adding them to the batter.
On low speed, cream butter with sugar until fluffy. Add eggs one at a time and mix until blended. Sift dry ingredients; add to eggs-and-butter mixture, alternating with milk. Mash 1/2 cup of berries and stir into mixture by hand. Add the rest of the berries whole and stir by hand. Grease muffin tins well with butter; grease the top surface of the pans as well. Pile mixture high in each muffin cup, and sprinkle the sugar over tops.
Bake at 375 degrees for 30 minutes.
