Mash banana and peanut butter together.
Add 1 cup of coconut and mix well. Depending on the size of the banana you use, you may need to adjust the amount of coconut so it is solid enough to roll into balls.
Take spoonfuls of the mixture and roll into balls.
Roll the balls in the other 1/4 cup of coconut, until well coated.
Store in the fridge for 1-2 days.
