Step Two: Pour the mixture into the Ninja Slushi machine and select the frozen or slush setting. Let it blend until it reaches a smooth, icy consistency.

Ninja Slushi Frozen Irish Coffee Recipe Tips
- Use Strong Coffee: Brew coffee slightly stronger than usual to ensure the flavor stands out when blended with milk and ice.
- Chill Ingredients First: Cold coffee and milk help the slush form faster and maintain icy consistency.
- Adjust Sweetness: Taste before freezing—add more simple syrup if you prefer a sweeter drink.
- Control Alcohol Flavor: Add whiskey gradually; you can adjust for a milder or stronger kick.
- Avoid Overfilling: Don’t exceed the max fill line on your Ninja Slushi machine to ensure proper blending.
- Optional Toppings: Whipped cream, chocolate shavings, or a dash of cocoa powder elevate the presentation.
- Serve Immediately: Slushy drinks are best enjoyed right away for the perfect icy texture.
Storing and Make Ahead Instructions
- Storing: If you have leftovers, store the slush mixture (before freezing) in an airtight container in the fridge for up to 24 hours. Avoid freezing fully prepared slush, as it can affect texture.
- Make-Ahead: You can mix all the liquids ahead of time and keep them chilled in the fridge until ready to blend. When ready, pour into the Ninja Slushi machine and blend for a fresh, icy treat.

Ninja Slushi Frozen Irish Coffee Recipe Faqs
Can I use regular ice instead of the Ninja Slushi machine? Yes, you can crush ice in a blender and mix with the coffee and whiskey, but the texture may be slightly less smooth than the Ninja Slushi version.
Can I make this drink non-alcoholic? Absolutely! Simply omit the Irish whiskey and add extra coffee or flavored syrup for depth.
How long can I store the slush mixture? Keep the liquid mixture in an airtight container in the fridge for up to 24 hours before blending. Avoid freezing fully prepared slush, as it can change the texture.
Can I adjust the sweetness? Yes, add more or less simple syrup depending on your taste preference.
What toppings work best? Whipped cream, chocolate shavings, or a sprinkle of cocoa powder are perfect for extra flair.
Can I use flavored coffee? Yes! Vanilla, caramel, or hazelnut coffee can add a fun twist to your frozen Irish coffee.
Can I make this ahead for a party? Prepare the liquid mix in advance and chill in the fridge, then blend in the Ninja Slushi machine just before serving for best texture.
