When I need a quick sweet treat that feels a little nostalgic but takes almost no effort, this strawberry milkshake is it. It’s creamy, fruity, and made with just a few simple ingredients you probably already have on hand. This milkshake delivers that classic strawberry flavor in under 5 minutes. No stress, no complicated steps.

Key Ingredients
- Frozen Strawberries: These help create that thick, icy texture we love in a milkshake. You can use fresh too, but frozen gives it that classic, frosty milkshake consistency—especially when using the Ninja Slushi.
- Milk: Helps everything blend smoothly and gives the shake a pourable texture. I use just enough to loosen up the mix without making it watery. You can go with dairy or any milk alternative you like.
- Sweetener or Sugar – This machine likes standard table sugar, allulose, and monkfruit from my personal testing and experience. I use monkfruit sweetener because it's zero calorie.
How to Make Ninja Slushi Strawberry Milkshakes
Detailed measurements and full instructions can be found in the recipe card at the bottom of this post.
- Combine milk, frozen fruit, and sugar or sweetener in a blender and blend until well combined.
- Add the mixture to the Ninja Slushi Machine.
- Allow the machine to churn and freeze the mixture until the machine beeps to signal the cycle is finished.
- Pull the lever on the spout to dispense the drink. Serve.
Troubleshooting Tips if You Have Problems with the Machine
- Check the Liquid Ratio – If the mixture is too thick, the machine may struggle to process it. Try adding 1-2 tablespoons of additional liquid (water or milk) and restart the cycle.
- Make Sure the Mixture is Cold Enough – The machine works best when the liquid is super cold. If your base wasn’t chilled before adding it to the machine, try refrigerating or briefly freezing it before processing.
- Let It Process Fully – The Ninja Slushi Machine may take a few minutes to reach the right consistency. Be patient and let it complete the cycle. If needed, restart the process.
- Check for Ice Blockage – If the mixture is freezing unevenly, it may be too cold or concentrated in one area. Let it sit for a minute, give it a gentle stir, and try again.
- Ensure the Machine is Properly Assembled – Double-check that all parts (including the lid and paddle) are locked into place. If something is misaligned, the machine may not operate correctly.
