Add all ingredients for the overnight oats to a large sealable container or jar and stir well. Seal and refrigerate overnight or at least 6 hours. If possible, stir oatmeal a few times as it sits.
After oatmeal has chilled overnight and is nice and thick, taste it for flavor. Add more peaches and/or pure maple syrup to taste.
Serve in bowls or glasses with chopped peaches and pecans. You can pack the oatmeal up in sealable jars and take this to work as a grab-and-go breakfast.
*The coconut milk makes this breakfast super rich and creamy! If you're watching your calorie intake, you an replace the coconut milk with more almond milk.
