In a food processor or your Blendtec add the coconut shreds, chia seed and ginger powder. Pulse until you have a flour - roughly 1 minute in Blendtec - 3 -4 minutes in your food processor.
Add you ripe banana and blueberries and mix until you have a dough.
Roll the dough out between two piece of parchment paper and use your cookie cutter to cut the shapes. You can also just take a pinch of dough and roll out the cookies and press them flat with a glass.
