In a saucepan, combine 2 cups of water, 1 cup of brown sugar, and 1 cup of granulated sugar.
Stir in 3 tablespoons of vanilla extract, ensuring it is well incorporated into the sugar-water mixture.
Add 2 tablespoons of allspice for a warm and aromatic flavor. Alternatively, you can use cinnamon if allspice is not available.
Place the saucepan on medium heat and bring the mixture to a simmer. Stir occasionally to help dissolve the sugars completely.
Simmer the mixture until all the sugar is fully dissolved. This usually takes about 5-7 minutes.
Allow the syrup to cool to room temperature. Once cooled, transfer it into a jar or bottle and store it in the refrigerator.
