Start with the cherries. Remove the pits, if needed. Then chop the cherries or leave them whole.
Into the mason jar, add the oats, cinnamon, ground flaxseeds, and chia seeds. Give the ingredients a couple of stirs to mix.
Then stir in the coconut milk, vanilla extract, and pure maple syrup. The liquid needs to be covering the oats.
To the top of the oats, place the cherries.
Cover with the lid and put into the fridge overnight, at least 6 hours.
In the morning, give the overnight oats a couple of stirs and, if necessary, add a splash of coconut milk to loosen the oatmeal. Give it a taste and if you need extra sweetness, stir in a teaspoon of pure maple syrup.
