I needed a Chick-fil-A frosted lemonade fix on a Sunday, which if you know, you know, so I made this Two-Ingredient Frosted Lemonade in the Ninja Slushi instead. Technically three things, but who's counting: water, a Crystal Light lemonade packet and sweetened condensed milk on MILKSHAKE. Comes out creamy and tart like the drive-thru version, way lighter on sugar thanks to the Crystal Light. My kid said it tasted like a lemon creamsicle and demanded a second. Tip: whisk the Crystal Light fully into the water before adding the condensed milk, or you'll get powdery streaks. That's it, that's the whole drink.

- Crystal Light Lemonade Packet1 packet
- Sweetened Condensed Milk14 oz
Makes ~64 oz
Directions
- 1Pour the water into a large pitcher.
- 2Empty the packet of Crystal Light Lemonade powder into the water and whisk until completely dissolved.
- 3Pour the entire can of sweetened condensed milk into the lemonade water.
- 4Whisk vigorously until the condensed milk is fully emulsified into the water, leaving no dense milk layers.
- 5Pour into the Slushi machine and select the MILKSHAKE mode.
- 6Run for 20 minutes until a thick, creamy frosted lemonade consistency is achieved, then dispense.
Tips
- Pour your mixed liquid (water plus Crystal Light plus condensed milk) directly into the Slushi bowl at room temperature, no pre-chilling needed.
- Check the consistency around the 30-minute mark; if it's still too liquid, let it churn another 10-15 minutes until it reaches that perfect scoopable slush texture.
- If your slush comes out too thick or icy, add a splash more water to the bowl next time and start over, since the machine can't adjust mid-churn.
Variations
- Swap the Crystal Light Lemonade packet for Raspberry Lemonade or Strawberry to change the flavor while keeping the two-ingredient simplicity.
- Use half sweetened condensed milk and half evaporated milk for a lighter, less rich version that still freezes properly.
- Stir in a tablespoon or two of fresh lemon juice after pouring into the bowl for a brightness boost, counting it as part of your liquid base.
FAQ
- Can I use regular milk or milk alternative instead of sweetened condensed milk?
- No, regular milk won't freeze properly in the Slushi machine because it lacks the sugar content that sweetened condensed milk provides. Sweetened condensed milk is essential for the texture.
- Why is my lemonade still liquid after 45 minutes?
- Your Slushi machine may not be getting cold enough, or your room is very warm. Make sure the bowl is fully seated and the machine is plugged in properly, and try placing it in a cooler area of your kitchen.
- Can I make this ahead and store it?
- Slush is best served right after the machine finishes, but you can pour it into a freezer-safe container and refreeze it for later; just give it a stir before scooping since it may separate slightly.
- How do I make this less sweet?
- Use half a packet of Crystal Light per batch to dial down the sweetness, and add a bit more water to compensate for the liquid volume.
