Ingredients

Instructions

  • In a large mixing pitcher or bowl, whisk together the cocoa powder and granulated sugar to break up any clumps. Pour in the milk and chocolate syrup, then whisk until fully combined.
  • Gently fold in the whipped topping until the mixture is smooth and creamy.
  • Pour the Frosty mixture into your Ninja Slushi or preferred ice cream maker and process according to the machine’s instructions until thick and creamy. Press milkshake for the Ninja Slushi.
  • Allow the machine to process. Let the machine run for 15-45 minutes, depending on the sugar content and temperature of the liquid. Mine took 20 minutes.
  • Once the cycle is complete, place a cup under the self-serve spout and pull the handle to dispense the Frosty.

Notes

I love to add a teaspoon or two of vanilla extract. It really takes it the next level.
Whole milk is the best choice for a rich, creamy texture like the original. 2%, skim milk, almond milk, and coconut milk will also work, but the Frosty will be thinner and less creamy.
How to Make This Using a Blender
You will need to use ice for thick texture. Just use a high-powered blender and blend until smooth. If the mixture is too thick, add more liquid a little at a time. If the mixture isn't thick enough, add ice and blend.
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 (sparkling water, juice, or even plain water) 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.
