For the batter:

1. Place your butter cubes, spices, demerara sugar and vanilla extract in your mug (or separate muddling bowl, if intending on serving in a glass).
2. Use your muddler to combine them into a paste.

For the drink:

1. Once the batter is done, move it into your serving glass, add your pineapple juice and hot water.
2. Stir until the batter melts and your drink acquires a consistent color and texture.
3. Finish with a dollop of whipped cream, a sprinkle of cinnamon and a cinnamon stick for garnish for an extra indulgent and festive drink idea!
