Would I be able to use a raspberry jam? Does it have to be orange.

Use something orange-hued, like apricot or peach, if you want the peanut butter to be the main focus. Something like raspberry would probably yield a more peanut-butter-and-jelly cookie in color and flavor (versus a straight-up peanut butter cookie). But if that sounds like what you're looking for, worth a try! Would love to hear how it turns out.
