Method
Make the protein base
- Whisk the milk, protein powder, peanut butter, sweetener, vanilla extract, and salt until very smooth and no protein powder clumps remain.
Freeze
- Pour the mixture into the Ninja Creami pint container, then freeze for 24 hours until fully set.
Churn and adjust texture
- Process on the Lite Ice Cream setting first; if the texture is grainy, add 1 tablespoon milk and re-spin.
Add mix-ins and serve
- Use the Mix-In setting to fold in the peanut butter chips or mini peanut butter cup pieces.
- Serve immediately for the creamiest, thickest peanut butter protein texture.
Notes
For a lump-free base, whisk until the mixture looks uniformly smooth before pouring into the pint—protein powder can hide clumps. Refrigerate any leftover in the pint and re-spin for best scoopability within 2 days; freezing again may make it icy. For a lower-sugar option, choose monk fruit sweetener (keep the rest the same) to maintain the dense, protein-forward texture.
