Hosted a late dinner and made this Espresso Martini with Baileys in the Ninja Slushi for the after-dinner crowd (strictly 21+). SToK cold brew, vodka, Kahlua and a splash of Baileys on SPIKED SLUSH, and it pours like a frozen coffee dessert with that creamy Baileys finish. My friend Marcus, who claims he doesn't like sweet drinks, had two and got philosophical about his career. It tastes like a coffeehouse and a nightcap had a baby. Tip: use real cold brew, not hot coffee cooled down, the concentrated stuff keeps it from going watery. Pace yourself, the coffee hides the booze.

Directions
- 1In a large pitcher, combine the black cold brew coffee, vodka, Kahlua, and Baileys Irish Cream.

- 6Garnish with whole coffee beans on top of each glass.
Tips
- Pour your chilled ingredients directly into the Slushi bowl and let the machine do the work for 20-60 minutes; colder starting ingredients will churn into slush faster than room temperature ones.
- If your slush is too thick to dispense, wait a few more minutes and the continuous churning will break it down; if it's too thin, you may need less simple syrup or more coffee next time.
- Use a tall glass to catch the slush from the tap, and have it ready before you start dispensing so you don't lose the texture.
Variations
- Swap Kahlua for Frangelico to make an espresso hazelnut version, keeping everything else the same.
- Cut the Baileys in half and add a shot of Irish whiskey for a more boozy, less creamy take.
- Replace half the cold brew with cold espresso shots for a stronger coffee flavor that stands up better to the sweetness.
FAQ
- Can I use regular instant coffee instead of cold brew?
- You can try it, but cold brew is smoother and less bitter, which tastes better in a sweet drink like this; if you use instant, dissolve it completely in cold water first so there are no particles to freeze.
- What if the mixture won't freeze into slush after an hour?
- Your starting liquid may have been too warm; make sure everything is chilled before pouring, and avoid opening the machine door mid-churn since it lets warm air in.
- Can I make this ahead and store it?
- The slush will separate and get watery if you leave it sitting; it's best to make it fresh and serve right away from the tap.
- Can I use a coffee substitute or less sugar to make it lighter?
- You can cut the simple syrup by a quarter and add a touch more vodka, or use half cold brew and half cold water to stretch it further; just know that less sugar means a thinner slush that may not hold texture as well.
