Preheat oven to 325 degrees F. Line a baking sheet with parchment paper and set aside.
In a large bowl, combine oats, cashews, and salt.
In a medium saucepan, heat mashed bananas, coconut oil, maple syrup, and coconut sugar over medium-low heat. Once coconut oil melts, remove from heat and stir in vanilla. Pour over oat/cashew mixture and stir to combine.
Spread the mixture onto the prepared baking sheet and bake for 30 minutes.
After 30 minutes, remove from oven and gently stir in coconut flakes and banana chips. Return to oven and bake for another 10-15 minutes, or until golden brown.
Remove from oven and let cool completely.
