Old Fashioned Orange Layer Cake

Cake
1 cup butter, softened
2 cups sugar
5 eggs
1/2 cup orange juice
1 tbsp orange zest
2 1/2 cups self rising flour
1 cup milk

Icing
1/4 cup butter, softened
3 3/4 cups powdered sugar
1/3 cup orange juice
1 tbsp orange peel

In a large bowl, cream butter and sugar until fluffy and light.  Add eggs, one at a time incorporating well after each addition.  Beat in orange juice and orange zest.  Alternating with the milk, beat in 1/3 of the flour, 1/2 milk, 1/3 flour, 1/2 milk, and finally the last 1/3 of the four.  Scrape down bowl after each addition.  Pour equal amounts into two greased and floured, 9" cake pans.  Bake at 350F for 25-30 minutes or until a toothpick comes out clean.  Cool 10 minutes before removing from pan to wire rack to cool completely. 

In a large bowl, beat butter until light and fluffy.  Add the powdered sugar, orange juice, and orange zest.  Beat until icing is smooth.  Spread icing between layers and then cover top and sides of cake.

Hint:  If you don't have self-rising flour, you can make it.  For each cup of self-rising flour, put 1 1/2 tsp baking soda and 1/2 tsp salt in to a one cup measuring cup and fill with regular flout until the cup is full and level.
