1 cup granulated sugar
2 large eggs
1 teaspoon vanilla

Heat oven to 375°. Grease 18 regular-size muffin cups (or 12 large size muffins). In bowl, mix butter until creamy. Add sugar and beat until pale and fluffy. Add eggs one at a time, beating after each. Beat in vanilla, baking powder and salt. With spoon, fold in half of flour then half of milk into batter; repeat. Fold in blueberries. Spoon into muffin cups and sprinkle topping onto each muffin. Bake 20–25 minutes, until golden brown and springy to touch.
