Preheat your oven to 350 F.
Mash the bananas in a bowl, then stir in the butter and nut butter.
Add the oats, cinnamon, coconut flakes and chia seeds. Mix until combined, then fold in the chocolate chip cookies.
Prepare a baking sheet with cooking spray. Form the dough into 6 medium-sized cookies (two per serving) and bake for 25 minutes, until they're firm to the touch and golden brown.
Let cool completely at room temp, then store in the fridge in meal prep containers!
