1. Put bananas in a freezer safe plastic bag and place them in the freezer over-night. The next day, remove bananas from the freezer and plastic bag and put them in a plastic bowl.
2. Now, with a fork, mash them until they make a paste. You might have to wait a few minutes to let them thaw out before you can mash them.
3. Once mashed, add peanut butter and continue mashing and mixing the banana and peanut butter. After a few minutes of mashing, it should be well mixed and ready to eat plain or it taste great spread on a piece of bread. Enjoy!
Keep the mash refrigerated!
