Preheat the oven to 350 degrees and line a cupcake pan with cupcake liners.
Add the cake mix, water, oil, and eggs to a large bowl or bowl of a stand mixer, and beat on high for 3 minutes, until you have a smooth batter.
Fill 24 cupcake cavities ¾ full with batter, transfer the pan to the oven, and bake for 12-15 minutes, until a toothpick inserted into the center comes out clean.
Transfer the pan to a cooling rack, and allow the cupcakes to cool for 1-2 hours.
Add both cans of frosting to a medium bowl, or stand mixer, along with ½ tablespoon of brandy, and beat on high for 1-2 minutes until light and fluffy.
Add the frosting to a piping bag equipped with the tip, and pipe the frosting onto the cupcakes.
Sprinkle gold sanding sugar onto cupcakes.
Fill the pipettes with brandy, and insert them into the cupcakes.
