Method
Make the protein ice cream base
- Whisk the milk, protein powder, peanut butter, sweetener, vanilla extract, and salt until very smooth and free of any protein powder clumps, scraping the bottom and sides as needed.
Freeze
- Pour the mixture into the Ninja Creami pint container, level the top, and freeze for 24 hours until fully firm.
Spin and troubleshoot texture
- Process on the Lite Ice Cream setting first, stopping to check for a grainy texture.
- If it looks grainy, add 1 tablespoon milk and re-spin on the Lite Ice Cream setting until smooth.
Add mix-ins and serve
- Use the Mix-In setting to fold in the peanut butter chips or peanut butter cup pieces evenly throughout.
- Serve immediately for the thick, creamy texture straight from the pint.
Notes
For the smoothest results, whisk until the batter looks glossy and lump-free before freezing; if your first spin is ever grainy, the extra 1 tbsp milk typically fixes it. Store leftovers in the freezer for up to 2 days, then re-spin on Lite Ice Cream for best texture. Freezing after serving is not ideal for mix-in crunch, but it’s workable. If you want a lower-carb option, choose a monk fruit sweetener and a vanilla or peanut butter protein powder that is unsweetened or minimally sweet.
