This ones definitely in the rotation because I just buy frozen organic fruit and bananas and this is so easy.
I occasionally have had those açaí you buy from store, but I’d not I just use the frozen fruit.
If no açaí packet, just do 1 cup frozen fruit, frozen banana (important to make it more fluffy!) add your fave protein powder (optional- but I use 1 scoop vanilla powder), add Peanut butter if you want (some add to mixture but I like putting on top).

I use nutribullet blender to blend.
