If you have lost or misplaced your bread machine instructions, you should check online. Many bread machine manufacturers have placed their instruction manuals on their websites. Just do a search for your bread machine manufacturer and include the word “instructions” or “manual” (i.e. XYZ bread machine instructions). The online manufacturer instructions should tell you if your bread machine can handle quick bread (i.e. banana bread) recipes.
I have been throwing all my ripened bananas in the freezer now for well over 2 years. When I need to use banana, I just go to the freezer and pull out what I need. They thaw ridiculously fast and I think the texture of a frozen banana is so much easier to work with than a ripened banana that has not been frozen. I wish I would have known about this ten years ago. I have no idea how many bananas I have tossed in the garbage.
Select Sweet and Light settings on your machine and add raisins as per your manufacturer’s instructions. They can be added in with everything else. Start your bread machine. After the first kneading cycle is over, the bread should be smooth and stretchy. It should feel dry when you touch it. If necessary, add flour by the tablespoon to adjust the bread.
