I'm getting ready to start my cupcakes for tomorrow's dinner - see previous post about chocolate and PB. Instead of using molds, I want to pipe peanut butter chips and allow them to harden. Is this possible? How would I go about doing it? Similar to ganache?

FYI - I tried using cream and peanut butter chips to make a ganache. It didn't work - not a good flavor and texture.

Good morning
I just saw this post, had a little company for Thanksgiving.
I'm curious; why did you want to pipe your own chips, for large decorations?
