Add bananas, milk of your choice, peanut butter powder, and protein powder to a blender. Blend until smooth.
Pour the ice cream mixture into a bowl, and add chocolate chips. Stir.
Place in a freezer for one to two hours, and stir again so the chocolate chips don’t settle on the bottom of the bowl.
If you prefer a more soft-serve ice cream, dig in after four hours. If you like a harder scoop, leave it in the freezer overnight. (The ice cream can be kept in the freezer for up to four months.)
Indulge!
Notes
Again, I choose the unflavored whey protein as I find sweetened protein powders can sometimes be overpowering when combined with simple ingredients. However, this recipe would also work well with chocolate or vanilla whey if you prefer.
