Hillary's Favorite Berry-Butter Smoothie

Hello! Today I bring to you a smoothie recipe! 
You know, to balance out the homemade popcorn recipe I shared here recently :) 
Chris had a smoothie similar to this one while he was traveling once + got all of the things to make it + i was super skeptical. I love berries + i love peanut butter, but together I wasn't sure. I tried it, and now I make this smoothie like three times a week, it's so so good!
