Pumpkin Bread

My friend shared this bread with me when my grandmother passed away.  I borrowed her cookbook Treasury of Christmas Recipes, and copied the recipe, keeping her addition of the chocolate chunks.

1 1/2 cup flour
1 cup packed brown sugar
1 cup solid pack pumpkin
1/2 cup butter
2 eggs
1 tsp baking powder
1 tsp baking soda
1/2 tsp salt
1 1/2 tsp ground cinnamon
1/2 tsp ground cloves
1/2 tsp ground ginger
1 cup semi-sweet chocolate chunks

In a large bowl, combine all ingredients, chocolate at end; beat until well mixed.  Pour into a greased 9x5x3 inch loaf pan.  Bake in preheated 350* oven 45-55 minutes or until a wooden pick inserted into center comes out clean.  Let cool in pan on wire rack 10 minutes.  Loosen edges; remove from pan.  Cool completely on wire rack.
