Hahah sure they are. I don't buy those frozen fruits from supermarket either. They don't smell good as I put them out for a little bit. I also freeze avocado and banana on occasion because I enjoy the cool, fresh, and ice creamy flavour they provide to my smoothie. I'll do Cocoa powder tomorrow as well:) I bet your combo will be delicious, with banana and peanut butter:) It sounds like a delicious chocolate chip frappe with milk froth, yet it's so much better for my stomach. Haha (and brain, too)
