Combine all ingredients (except nuts or chocolate chips) in a mixing bowl and beat on medium speed for about one minute. Then add the nuts or chocolate chips (I'm all about adding the chocolate!) and stir them in with a spoon. Bake for 30-35 minutes at 350.
This recipe makes 4 mini loaves (I love the Pampered Chef mini loaf pan that's a baking stone). You could also pour the mixture into a mini muffin pan. If you do the mini muffins, they only need about 10 minutes in the oven. Or you could do one large loaf of banana bread and that would take about an hour to bake.
