Pumpkin Spice Bundt Cake

1 1/2 sticks (3/4 of a cup) butter, softened
1 1/8 cup whole wheat flour
1 1/8 cup white flour
2 t baking powder
1 t baking soda
1 t cinnamon
1/2 t nutmeg
1/2 t salt
1/2 can of pumpkin
3/4 cup buttermilk
1 t vanilla
1 1/4 cups sugar
3 large eggs

Beat butter and sugar together until pale and fluffy. Add vanilla and then eggs. Alternate adding dry ingredients, pumpkin and buttermilk. Bake at 350 for 45 minutes or until a skewer stuck in comes out clean.

I always double this since I have 2 bundt cake pans. One isn't enough for our family. I also use plain yogurt instead of buttermilk sometimes.
