Preheat the oven to 350°F (180°C) and line a baking tray with parchment paper. Set aside.
Add the softened butter and brown sugar to the bowl of your stand mixer and cream them together until smooth.
Add the maple syrup, vanilla extract and milk and mix together.
In a separate bowl, add the rolled oats, dessicated coconut, all purpose flour, baking soda, salt and cinnamon and mix together.
Add the dry ingredients in with the wet ingredients and mix by hand (don't use your electric mixer for this part, just stir in with a spoon) into a thick cookie dough.
Break off pieces of the cookie dough and roll into balls. Place them evenly onto your parchment lined baking tray. Aim to get 20 cookies from your batch.
Flatten the cookies slightly with a fork.
Bake for 12 minutes until the cookies are lightly golden on top.
Let the cookies cool and firm up on the baking tray before moving them.
