No sugars, NO creams, NO milk! Healthy Banana & Peanut Butter Ice Cream!!

So, I just made this, swapping out the Peanut Butter for Nutella (bcuz I didn't have enough pb), and it was so Yummo-f'ing-licious! . My picky eating 9yr old even loved it, & he hasn't like any of the million smoothies I've made. Only changed one thing bcuz my son ate up all the peanut, I swapped in Nutella (fake hazelnut I''m aware). I thought I would get to devour this all to myself, but now the picky eater wants to eat something out of the Vitamix :(
