AI recently purchased some powdered peanut butter but I have no clue what to do with it. I'll probably put some in a smoothie, but other than that, I am clueless. Any ideas?

Thanks so much!

Is is PB2? I made a chocolate banana pb2 smoothie. I'm sure it will taste great in butter cream or a cake :) 

AIt's not that brand, but I think it is the same kind of item, though I've never had the PB2 before.

I use it to make peanut butter buttercream. Just add it to any butter cream recipe. Works great and don't need much for great peanut butter taste. Can also use for peanut butter mousse.
