Preheat oven to 350°F (175°C).

Sift together cake flour, baking powder, baking soda, salt, cinnamon, and nutmeg in a bowl.

In a separate mixing bowl, combine pumpkin, sugar, milk, and eggs.

Add the dry ingredients and soft butter to the wet ingredients.

Mix until well blended.

Stir in chopped nuts.

Pour the batter into a loaf pan.

Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean.

Let the bread cool in the pan for a few minutes before transferring to a wire rack to cool completely.

Slice and serve.
