Craving that icy cola flavor without the sugar? This Coke Zero Slushy hits the spot, cold and fizzy with that familiar taste you know. Since sugar-free drinks don’t freeze the same way, I added a little monk fruit-erythritol blend to help it form fine ice crystals and keep a smooth, drinkable texture instead of turning solid. I also added a splash of lemon juice to balance the sweetness, since the acidity helps brighten the flavor and tone down the lingering aftertaste that sugar substitutes can leave behind.
Whisk everything together in a separate pitcher, adding the monk fruit-erythritol blend slowly because it can make the Coke fizz up and overflow if you pour it too fast. Once mixed, pour it into the Ninja SLUSHi and select Slush mode. Let it run until it reaches your preferred texture, then enjoy a frosty, zero-sugar treat that tastes like an ice-cold Coke straight from the fountain, cool, crisp, and completely guilt-free.

The Ninja SLUSHi Max is my top recommendation thanks to its larger capacity, faster freezing, and convenient Slush Assist setting. It can make bigger batches in less time, making it ideal for parties and entertaining. Slush Assist automatically adjusts the settings to help you get the perfect consistency without the guesswork.
