Banana and Peanut Butter 4 Ingredient Ice Cream

I always make this banana and peanut butter 4-ingredient 'ice cream' for my family! It is a great recipe for vegan and vegetarian diets, just replace the peanut butter with organic peanut butter or another nut butter. Substitute water for milk if desired. The more milk you add, the thinner and soupier your ice cream will be. Serve it with sliced fresh fruit or handmade whipped cream.
