Peel the bananas and slice them in half, place the 4 halves straight up in your container.
In small blender or blender bottle combine 1 cup milk, protein powder, vanilla extract and combine then pour over bananas.
Cover and place in the freezer on a flat surface for 24 hours.
Once frozen, place in your ninja creami and press ‘light ice cream’.
Once that is done it might slightly crumbly. Add in 1 tbsp milk (only if it’s crumbly), chocolate and walnuts and press it down the middle, then put it back in the machine and press respin.
NOTES
Once you do the first spin, if there is no hole in the middle of the ice cream you can take a butter knife and put it down the middle, spin it and scoop some out so you can easily add your mix ins
