Blueberry Muffins

I made these last night with scrambled eggs and hashbrowns and it made for a perfect "breakfast for dinner" meal... one of our favorites!
Ingredients:
2 cups fresh blueberries
1/4 cup all-purpose flour
2 cups all-purpose flour
2 teaspoons baking powder
1 teaspoon salt
1/4 cup margarine
1 1/2 cups white sugar
2 eggs
1 teaspoon vanilla extract
1 cup milk

Directions:
1. Preheat oven to 375 degrees F (190 degrees C). Grease muffins tins, or line cups with paper liners.
2. Sprinkle 1/4 cup flour over blueberries, and stir to coat berries thoroughly
3. In a small bowl, whisk together 2 cups flour, baking powder and salt.
4. In a large bowl, cream margarine, and gradually mix in sugar. Beat eggs, and stir into creamed mixture along with vanilla. Stir in milk alternately with flour mixture, mixing well after each addition. Fold in berries. Fill muffin cups 2/3 full with batter.
5. Bake for 25 minutes.
