Mix the milk, coconut oil and agave syrup in a bowl
Add the flour, chia, baking powder, salt and mix
Mix in the oats and roasted and ground hazelnuts
Scoop 1 tablespoon of the mixture at a time and put on the baking tray; press to get a thin and round cookie
Bake for 15 minutes
If you're making really thin cookies, normal baking time is about 15 minutes. But this can be +/- 5 minutes based on your oven. For thicker cookies the baking time might be higher. You'll know they're baked once they have slightly dark brown color on the edges and a golden brown in the middle.
