Stir sifted einkorn flour, baking soda, baking powder, salt, cinnamon together in a separate bowl
In a large bowl (I used my KitchenAid stand mixer with paddle attachment but you can use a hand mixer) beat butter until light and fluffy (about 2 mins)
Slowly add coconut sugar and beat for about 2 minutes
Beat in banana, eggs and vanilla until it's just combined
Using a wooden spoon, stir in flour mixture, oats, shredded coconut and chocolate chunks. The batter will be slightly stiff and it make take a little muscle power to mix thoroughly
Drop by the tablespoon full on a greased baking sheet, or a baking sheet with a silpat mat (these cookies don't expand too much so you can leave about an inch and half in between each cookie)
