Here is the recipe my mother gave me when I was 12. She makes about 40 loaves each Christmas for neighbors. It's the most requested thing she makes. I now make it for my neighbors, and I always have people asking for more!
Pumpkin Bread
4 C. sugar
4 C. pumpkin (1 large can)
1 C. oil
5 C. flour
4 tsp. baking soda
1 tsp. salt
1 Tbs. cinnamon
1 tsp. cloves
1 C. raisins (or chocolate chips)
1 C. nuts optional
Mix together the sugar, pumpkin and ol. Add the flour, baking soda, salt, spices, raisins and nuts. Grease 3 large loaf pans and fill half full with batter. Bake for 1 hour at 325-350 degrees. The loaves will rise.
You can use smaller loaf pans, but you'll need to adjust your cooking time.
