Add the water, brown sugar, molasses, ginger, and cinnamon sticks to a small saucepan.
Bring the mixture to a simmer and cook for 10 minutes.
Remove the pan from the heat and stir in the vanilla extract. Let the mixture cool, then transfer it to an airtight container.
Notes
Do I add the cinnamon sticks to the jar with the syrup? No. The cinnamon flavor will already be infused during the steeping process, so there’s no need to include the sticks in the jar.Can this be given as a gift? Yes. Just make sure the jars or bottles are thoroughly sterilized, and give the syrup right away so the recipient has the full two weeks to use it while it’s fresh.What is the best kind of molasses to use? Unsulfured molasses is best for syrups and baking because it’s lighter and sweeter. Sulfured molasses has a stronger, smoky flavor that’s better for savory dishes.Can I make the syrup a little thicker? Yes. You can simmer it a bit longer to reach your desired consistency, but remember it will thicken more as it cools, so don’t overdo it.
