Here is one of my oldest banana bread recipes from a "Farmers Journal" bread book of some kind. The recipe is almost illegible it is so old, so I am glad I can preserve it now. You can make it as a basic banana nut bread, or add cranberries, chocolate chips or anything else to jazz it up.
1Preheat oven to 350.
Mash the bananas with a fork or other kind of masher. Set aside.
Whisk together the dry ingredients in a large mixing bowl.That would be the flour, sugar, baking powder, salt and oats. Cut the butter in with a pastry cutter or your fingers.
2Put liquids in a bowl and mix together. The milk, egg and vanilla. Add to the mashed bananas and put all this into the dry ingredients, mixing with a whisk or wooden spoon until just mixed. Fold in the walnuts. At this point you might want to fold in other add-ins. Or scoop out some batter, add say, chocolate chips to it and put into a smaller loaf pan, then put something else in the rest of the batter for yet another pan.
3Pour into an 8" loaf pan or 2 smaller pans. Bake until golden brown and a straw poked through the middle comes out clean. Just when you think its done, give it at least another 5 minutes. Sometimes they look done, then as they cool, they collapse. An 8" loaf pan will take about 1 hour and 15 minutes to bake.
4Let cool in pan for 5 minutes, then remove to finish cooling on a rack.
