A blogger friend, Max, suggested that I use her orange frosting:
Fresh Orange Icing
6 tablespoons butter or margarine
4 cups powdered sugar
2 tablespoons grated orange rind
1/4 to 1/2 cup orange juice
1 tablespoon lemon juice
1/4 teaspoon salt
Cream the butter until light. Beat in the orange rind, salt and lemon juice. Add the powdered sugar and orange juice alternately--start with 1/4 cup orange juice and add a few drops more at a time until the consistency is right. Beat until light and fluffy. Frosts two 9 inch layers.
To frost the top of a 13x9 cake, use 1/4 cup butter, 3 cups powdered sugar, 4 teaspoons grated orange rind, 3 tablespoons (plus) orange juice, 2 teaspoons lemon juice and a dash of salt.
I didn't have any fresh oranges, but I used dried orange peel and fresh not from concentrate OJ. I'm serving this with Sunday supper this weekend.
