Preheat oven to 350 degrees F. Grease two (2) 9x5-inch loaf pans.
In a large bowl, cream butter or margarine and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Sift in flour, baking powder, baking soda, and salt; stir until dry ingredients are moistened. Fold in bananas and pecans.
NOTE: Bake all quick breads as soon as the ingredients are assembled. Since high temperatures are often called for, it is best to bake them in the center of the oven, as the heat in the top third of the oven will be too intense.
Pour banana pecan bread batter into prepared loaf pan and bake 55 to 60 minutes or until a toothpick inserted in the center comes out clean. Be sure and poke the toothpick to the center of the loaf. A good check is to use an instant digital thermometer to test your bread. The internal temperature of the bread should be at 200 degrees F. when done.
This is the type of cooking and meat thermometer that I prefer and use in my cooking. I get many readers asking what cooking/meat thermometer that I prefer and use in my cooking and baking. I, personally, use the Thermapen Thermometer shown in the photo on the right. Originally designed for professional users, the Super-Fast Thermapen Thermometer is used by chefs all over the world.
Remove from oven and cool on a wire rack 10 minutes; remove from pan. Cool completely before slicing.
Storage: Breads that contain fruit, nuts, or butter may be stored for 2 or 3 days, well wrapped in plastic wrap or aluminum foil. May be frozen for longer storage. After thawing frozen breads, reheat them in a 400 degree F. oven for a few minutes before serving.
