Williamsburg Orange Cake

I always try to make a cake for Christmas since we celebrate it first as Jesus' birthday. This was the one I made this year.

Williamsburg Orange Cake
from my friend, Marsha

Cake:
2 1/2 cups all-purpose flour
1 1/2 cups sugar
1 1/2 tsp baking soda
1/4 tsp salt
1 1/2 cups buttermilk
1/2 cup butter, softened
1/4 cup shortening
3 large eggs
1 1/2 tsp vanilla
1 T grated orange rind or 2 T orange juice
1/2 cup finely chopped pecans

Combine all the ingredients except the pecans, 30 seconds on low and then 3 minutes on high. Add pecans.

Pour evenly into 3 greased and floured 8-inch cake pans. Bake at 350 degrees for 30-35 minutes. Cool in pans 10 minutes. Remove and cool completely.

Frosting:
3/4 cup butter, softened
6 3/4 cups powdered sugar
1 1/2 T grated orange rind
7 1/2 T orange juice

Mix in blender until it is spreading consistency. You can add little bits of orange juice if you need more liquid.

Store in refrigerator.

You must use butter in the cake. My grandma tried to make this years ago when she was still living after I had made it for her for her birthday. She used margarine. It didn't work.
