In a medium saucepan, combine the granulated sugar and water.

Place the saucepan over medium heat, stirring constantly until the sugar dissolves completely.

Once the sugar is dissolved, bring the mixture to a gentle simmer.

Remove the saucepan from the heat and stir in the pure vanilla extract.

Let the syrup cool to room temperature in the saucepan.

Once cooled, pour the syrup into a glass jar or bottle for storage.

Seal the jar and store it in the refrigerator.
