Banana bread is a quick bread recipe, which means you don't add yeast. Instead, baking powder and baking soda are the leavening agents used to cause a faster rise than required for yeasted bread. Using the bread machine makes for an almost completely hands-off process with very little mess: almost everything gets mixed right in the pan you bake it in.

All bread machines are different, so it's very important to follow the manufacturer's instructions for the model you own in order to ensure success. Also, make sure the bread machine is ready to go before you start mixing. Once the wet and dry ingredients are combined in the pan, it needs to be mixed and baked right away. Many have a setting for quick bread, or some people use their machine's rapid bread program or manual settings. At the end of the cycle, you can always use a toothpick to check the doneness of your bread and bake it a little longer if it's not thoroughly baked.
Add the eggs, butter & bananas into the bread pan and then add the other ingredients. Try to follow the order of the ingredients listed above so that liquid ingredients are placed in the bread pan first and the dry ingredients second. Be aware that the bread pan should be removed from the bread machine before you start to add any ingredients. This helps to avoid spilling any material inside the bread machine. The bread machine should always be unplugged when removing the bread pan.
