In a medium saucepan, combine the apple cider, brown sugar, and cinnamon over medium heat. Bring the mixture to a boil. Reduce the heat to a simmer and cook for 5-7 minutes, until the sugar dissolves.
Remove the pan from the heat and stir in the vanilla extract.
Allow the mixture to cool completely.
Store in an airtight container in the refrigerator for up to two weeks.
Notes
• Fresh apple cider creates the richest apple flavor.• Let the syrup cool completely before transferring it to a storage container.• Stir into coffee, lattes, chai, cocktails, or hot apple cider.• The syrup will thicken slightly as it cools.• Shake or stir before using if it has been sitting in the refrigerator.
