Method
Make the protein base
- Whisk milk, protein powder, peanut butter, sweetener, vanilla, and salt together until very smooth, ensuring no protein powder clumps remain. The mixture should look pale tan and uniform without dry spots.
- Pour the mixture into the Ninja Creami pint container, leveling the top for even freezing. Fill to the marked line and wipe any drips from the rim.
Freeze and process
- Freeze the pint for 24 hours so the base is fully solid. Keep it undisturbed in the coldest part of your freezer.
- Process on the Lite Ice Cream setting first, then check for a slightly grainy texture. If it is grainy, add 1 tablespoon milk and Re-spin on Lite Ice Cream.
Add mix-ins and serve
- Use the Mix-In setting to fold in peanut butter chips or peanut butter cup pieces. Stop when the mix-ins are evenly distributed without large chunks pooling.
- Serve immediately for the thickest, creamiest texture. Keep the pint lid closed between steps to prevent softening.
Notes
For the smoothest churn, whisk until the protein powder is completely dissolved with no visible clumps. Freeze in the pint for up to 2 weeks; for best texture, process within 3 days after freezing. Freezing leftovers is not recommended because it can become icy after serving. If you want it lower in calories, use monk fruit sweetener and a lower-sugar protein powder.
