25gpowdered peanut butter or natural peanut butter
40gwhey protein isolate based protein powder (I use Bare Blends Vanilla WPI)
100ghigh protein plain yoghurt (I used Chobani Fit)
225-250gmilk, to fill the tub (I used high protein plain milk)
25gmaple syrup (as needed, see notes)
Instructions
Blend the ingredients briefly in a high powdered food processor until combined. Blending too long will start to foam up the protein powder, but not blending leaves chunkier edges when the ice cream freezes. If your protein powder is sweet, leave the maple syrup out for now.
Pour the mixture into your Ninja Swirl 470ml tub. If you think your mixture needs the maple syrup, stir it in here. You can also stir in milk to reach the fill line. Make sure the bottom mechanism is closed before you pour the mixture into the tub.
Freeze for 24 hours with the lid off. Freezing with the lid off can help stop your mixture from forming a hump which can damage the blades of your machine.
When ready to eat, process using the 'soft serve' and 'lite ice cream' functions. As mentioned in the body of the post, I found the Creami Fit setting made the mixture too fluffy for soft serve (but it was interesting as a scoopable ice cream).
You can eat this ice cream as a scoop or soft serve. If you choose soft serve, you will lose some of the mixture at the bottom of the tub. The machine can't seem to process that bottom section - you can of course eat it out of the tub, but in every recipe I have tried that bottom section is a bit icy.
Notes
With the ingredients specified, this recipe can contain approximately 67g protein. This depends on the protein powder and other ingredients you use.
I do recommend blending the mixture before pouring it into the tub. In the unblended version I tested, the powdered peanut butter didn't emulsify as nicely and soft of sat around the edges of the tub.
See notes in the body of the post for tips, ingredients substitutions and the Creami Fit setting.
