Cream butter, sugars, cinnamon and pumpkin.

Add eggs and mix lightly.

Add vanilla and sour cream, mix well.

Mix in the rest of the dry ingredients and stir just until combined.

Stir in cinnamon chips.

Topping:

tb sugar

tsp cinnamon

(Shortcut: use McCormick's cinnamon sugar like I did and generously sprinkle on top.)

Separate into 2 full size loaf pans.

Mix 3 tb sugar and 3 tsp cinnamon and sprinkle generously over the batter in each loaf pan.

Bake at 350 for 40 minutes or until toothpick comes out clean.
