2 tablespoons butter
¼ cup white sugar
2 ¾ cups all-purpose flour
1 teaspoon baking powder
½ teaspoon salt
1 cup butter
2 cups white sugar
1 teaspoon vanilla extract
2 cups fresh blueberries
¼ cup all-purpose flour
Preheat oven to 325 degrees F (165 degrees C). Grease a 10-inch tube pan with 2 tablespoons butter. Sprinkle pan with 1/4 cup sugar.
Mix together 2 3/4 cups flour, baking powder and salt. Set aside.
In a large bowl, cream together 1 cup butter and 2 cups sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla. Gradually beat in the flour mixture. Dredge blueberries with remaining 1/4 cup flour, then fold into batter.
Pour batter into the prepared pan.
Bake in a preheated oven for 70 to 80 minutes, or until you brush your toothpicks in the middle of the cake. Let it cool in the pan for 10 minutes, then flip it over a wire rack and cool completely.
