Use canned pumpkin puree, not pumpkin pie filling, to maintain proper sweetness and texture., You can substitute applesauce for canola oil depending on preference or what you have on hand; applesauce produces a denser loaf while oil creates a richer crumb., Variations include adding chopped nuts like walnuts or pecans, substituting some chocolate chips for butterscotch chips, or swapping chocolate chips for dried cranberries or raisins for a fruity twist., Store cooled bread wrapped tightly at room temperature for up to 3 days, in the refrigerator up to one week, or freeze wrapped for up to 3 months., Reheat frozen slices in the microwave or oven; butter or cream cheese spreads taste great warmed., Avoid overmixing batter and opening the oven door frequently during baking to prevent sunken loaves.
