The drink is noted for the almost unnotIceable taste of alcohol, even when made as a double. it’s like an Irish Coffee with the Punch of Muhammad Ali.Pour 1/3 of a can (5 oz) of Rockstar Roasted Latte Energy Drink into a rocks glass. Pour into a Shot Glass 1/3 of a shot of Baileys Irish Cream, and 2/3 of a shot of Vanilla Vodka. Drop the Shot Glass into the Rockstar and pound it.
