Preheat oven to 350ºF and butter a 9 X 5 inch loaf pan

Whisk together dry ingredients and in a separate bowl combine the milk and vanilla. In a large bowl, beat the butter until creamy. Gradually add the sugar to the butter while beating at high speed. Beat in the eggs, one at a time, then add pumpkin puree and mix in on low speed until just blended.

Next, add the flour in 3 parts, alternating with the milk mixture in 2 parts. Beat on low speed, or use a spatula or wooden spoon, scrapping the sides of the bowl until the batter is smooth. Add 1/2 c. each of chopped walnuts (or pecans) and semi-sweet chocolate chips.

Scrape into the bread pan and spread evenly. Bake for about 60 minutes, and check for doneness with a toothpick inserted into the center of the loaf, which will remain clean upon removal when fully cooked.
