In a mixing bowl cream butter, eggs, and sugar together. Add milk and molasses and continue mixing. Add flour, baking soda, salt and spices and mix well. Fold in blueberries.
Spray 2 regular sized loaf pans with cooking spray. Pour half the batter in each pan and sprinkle the top with 1/2 cup walnut pieces. Cook in preheated 350 degree oven for 35 to 40 minutes. Let cool 10 - 15 minutes in pan.
Remove, slice and enjoy!
I make this in two loaves because it is easier to slice. This bread is so light it tends to crumble if you make one big loaf.
