Place nuts, milk, fresh banana, vanilla, and salt in high-powered blender and blend until smooth.
Add frozen bananas. Blend on high speed just until lumps disappear, but do not over blend or mixture will become runny.
Mix in slightly chopped or whole berries.
Serve immediately.
Notes
You'll need a high-power blender to make this super thick, frosty, and creamy ice cream.Be sure to only blend this smoothie just long enough to blend the banana pieces. If blended any longer the smoothie will lose its frosty thickness.Yield: 1 to 2 servings
