Place all the ingredients in a medium saucepan, and whisk to combine.
1 cup water, ¾ cup dark brown sugar, 1 to 4 tablespoons unsulphured molasses, 1 ½ teaspoons ground ginger, ½ teaspoon ground cinnamon, ¼ teaspoon ground nutmeg, ⅛ teaspoon ground allspice, ⅛ teaspoon ground cloves, 1 teaspoon vanilla extract
Bring the ingredients to a boil over medium-high heat, then lower to a simmer. Don't walk away while the syrup cooks because it can easily boil over.
Simmer for 5-6 minutes then remove from heat. Allow the syrup to cool before transferring to a heat-safe, sealable container.
Use 1-2 tablespoons, or adjust to taste, per 8 ounce cup of coffee.

*The calories listed are an approximation based on the ingredients in the recipe card and a serving size of 1 tablespoon of simple syrup. Actual calories will vary.*For more information, tips, and answers to frequently asked questions, please refer to the post. Storage information is listed under "Storage" in the post.*For a thicker syrup, use ¾ cup of water.*For a sweeter syrup with a light molasses flavor, use 1-2 tablespoons of molasses. For a less sweet syrup with a heavier molasses flavor, use 3-4 tablespoons of molasses. I usually use 3-4 tablespoons, and it's strong.
