In a saucepan heat the jelly or preserves over low heat for one minute or until liquefied (this can also be done in the microwave for 30 seconds) and allow to cool.
Drizzle the jelly and peanut butter equally between the bowls of yogurt and swirl the contents together.
Serve.
* If using store bought peanut butter such as Jif or Skippy, melt in the microwave for about 15 seconds to soften. I use organic peanut butter which tends to already be a bit more liquified than most name brands.
