Step 1

In a medium saucepan, combine the granulated sugar, brown sugar, water, and vanilla. Bring to a simmer over medium heat, stirring until the sugar dissolves. Add the cinnamon and continue cooking until the syrup thickens slightly, about 3 minutes total. Remove the pan from the heat and let the syrup cool to room temperature, about 20 minutes.

Step 2

The syrup will keep in an airtight container in the refrigerator for up to 1 month.

Step 3

Enjoy!
