Add the oats, water, and cinnamon stick to a small saucepan and bring up to a boil.
Turn the heat down and simmer (covered) for 30 minutes.
Strain the liquid through a fine mesh sieve and discard the oats.
Stir in the honey and vanilla.
Serve warm.
Notes
Recipe Inspiration: This recipe was inspired by and adapted from Tosca Reno's recipe for Oat Tea in her Eat Clean Cookbook.
Vegan Version: Use maple syrup, agave nectar, or sugar as the sweetener instead of honey.
Spices: Cinnamon is a classic pairing with oats and it's delicious! However, feel free to play with the spices here. Cloves, nutmeg, allspice, and ginger would all be good.
