My wife grew up going to an old-school soda fountain and has very strong opinions about malts, so making a Chocolate Malt Milkshake in the Ninja Slushi was a real test. Whole milk, chocolate syrup, a little heavy cream, and malted milk powder on the MILKSHAKE preset, and it comes out thick and creamy with that toasty malt flavor you can't fake. She took one sip and said it passed, which from her is basically a standing ovation. Don't skip the malted milk powder. It's the whole point, and without it you've just got chocolate milk that thinks it's a shake.

Tips
- Pour your milk, cream, and chocolate syrup mix into the Slushi bowl at room temperature, no need to chill it first.
- Give the machine the full 20-60 minutes to churn and scrape. Checking it at 15 minutes won't help, but peeking at 45 minutes tells you if you're close to that perfect slush texture.
- Malted milk powder dissolves better when you mix it with a little of the milk before pouring everything into the machine.
Variations
- Swap chocolate syrup for 2-3 tablespoons of cocoa powder mixed with a tablespoon of sugar for a less sweet, more intense chocolate flavor.
- Add a teaspoon of vanilla extract or a tablespoon of peanut butter to your liquid base for a flavored twist before pouring.
FAQ
- Can I use skim milk instead of whole milk?
- Yes, but whole milk gives you a creamier slush texture. Skim will work fine, just expect it a bit lighter and icier.
- What if my Slushi didn't freeze into slush after an hour?
- Check that your Slushi bowl is actually cold enough and seated properly in the machine. Also make sure your base isn't too thick or syrupy, which can slow the churning action.
- How do I store leftover slush?
- Transfer it to a freezer-safe container and cover it. It'll stay good for a few days, but stir it before scooping since it'll harden up over time.
- Can I make this lighter and less sweet?
- Use less chocolate syrup or replace some of it with cocoa powder, and try half and half instead of heavy cream to cut the richness.
