Iced Orange Muffins

I've wanted to make an orange muffin/cupcake to expand upon a family orange cookie recipe that is one of my favorites.

Iced Orange Muffins

1 cup butter, softened
1 cup sugar
1/2 cup orange juice
3 eggs, separated
1 tsp vanilla
2 cups flour
2 tsp baking powder
1/4 tsp baking soda

Beat egg whites until light and fluffy.  In a separate bowl, cream together butter and sugar.  Add in orange juice and vanilla.  Add in egg yolks.  Gently fold in beaten egg whites.  Gradually add in dry ingredients.  Bake for 15 minutes at 325°F or until tops are a light golden brown.  Let cool and then ice.  Makes 12 jumbo muffins
