1/3 cup butter, soft
4 ounces cream cheese, softened
2 cups sugar
1 egg white
1 tablespoon grated lemon peel
2 teaspoons vanilla extract
2 cups fresh or frozen unsweetened blueberries
3 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup (8 ounces) lemon yogurt
1-1/2 cups confectioners' sugar
1/4 cup lemon juice
Directions Preheat oven to 350°. Grease and flour a 10-in. fluted tube pan. In a large bowl, cream the butter, cream cheese and sugar until blended. Add eggs and egg white, one at a time, beating well after each addition. Beat in lemon peel and vanilla.
Toss blueberries with 2 tablespoons flour. In another bowl, mix the remaining flour with baking powder, baking soda and salt; add to creamed mixture alternately with yogurt, beating after each addition just until combined. Fold in blueberry mixture.
Transfer batter to prepared pan. Bake 55-60 minutes or until a toothpick inserted in center comes out clean. Cool in pan 10 minutes before removing to wire rack; cool for 15 minutes.
In a small bowl, mix confectioners' sugar and lemon juice until smooth. Gradually brush onto warm cake, about one-third at a time, allowing glaze to soak into cake before adding more. Cool completely. Yield: 12 servings.
