Blueberry Bars recipe.

Ingredients
1 cup butter or margarine, softened
1 3/4 cups sugar
1 teaspoon vanilla extract
3 cups all-purpose flour
1 1/2 teaspoons baking powder
1/2 teaspoon salt
1 (21 ounce) can blueberry pie filling
1/8 teaspoon ground nutmeg
1 1/4 cups confectioners' sugar
2 tablespoons lemon juice
1 tablespoon butter or margarine, melted

Directions
In a large mixing bowl, cream butter and sugar. Add eggs, one at a time, beating well after each addition. Beat in vanilla. Combine the flour, baking powder and salt; add to creamed mixture just until combined. Spread half of the batter into a greased 15-in. x 10-in. x 1-in. baking pan. Spread with pie filling; sprinkle with nutmeg. Drop remaining batter by teaspoonfuls over the top.
Bake at 350 degrees F for 40-45 minutes or until golden brown. In a small bowl, combine the glaze ingredients until smooth. Drizzle over warm bars.
