Heat whisky in saucepan and add 3 tablespoons brown sugar. Stir until the sugar is completely melted. Place in a mason jar to cool. Once cooled, add peeled ginger root and a splash of vanilla extract. Cover and let sit from about 3-4 days.
If you’re feeling fancy, you can rim your glass with brown sugar.
In a low ball glass, add 1 teaspoon brown sugar and 3 splashes of bitters. Muddle the sugar, rotating the glass until the sugar and bitters has layered the bottom of the glass. Add one large ice cube or 2-3 smaller ice cubes. Pour in the Gingerbread whisky and ginger ale.
