Preheat oven to 350 degrees and grease a regular loaf pan (or you can use 2 smaller loaf pans)

In a large bowl, beat together the butter, pumpkin, eggs, and brown sugar until blended.

Add in the remaining ingredients and mix just until combined.

Pour batter into the prepared loaf pan. Bake at 350 degrees for 35 (25 for smaller loaves) minutes, until a toothpick inserted in the center comes out clean. Makes 1 loaf.
