Boil the ginger in water for at least 10 minutes (longer if you want a stronger ginger taste!)
Meanwhile, heat the oat milk (a frother is best but if you don't have one you can whisk in a pot on the stove)
Serve the ginger tea in your favourite mug, and stir in cinnamon and maple syrup until combined
Pour your frothy oat milk in on top and enjoy!
