Mix together the mashed banana, peanut butter, coconut oil, and maple syrup in a large bowl. Add the remaining ingredients and mix thoroughly.

Press the mixture into a parchment lined 8x8 baking dish.

Smooth with a spatula and put it in the freezer for at least an hour.

When the bars are frozen, remove them from the pan and slice into individual bars.

Wrap in foil and store in the freezer.
