In a large mixing bowl, mash banana then add in the rest of the cookie base ingredients (oats, seed/nut butter, vanilla, coconut, honey, cinnamon, chocolate, and flax) and mix well until a batter forms.
Line a baking tray with parchment paper and roll even size balls of dough (about 2 tbsp each) and place on parchment paper. Using your hand or the back of a spoon, flatten cookie balls to be flat (about 1 inch thick) and place in the refrigerator for 5-10 minutes.
While cookies are in the refrigerator, heat up coconut oil and chocolate chips in the microwave (about 30 seconds) or in a pan until they become a liquid.
Remove cookies from the refrigerator and use a fork to drizzle chocolate mixture over cookies and sprinkle the top of each cookie with coconut flakes.
Place cookies back in the refrigerator for 30 minutes and ENJOY!
