Melt the chocolate using the double boiler method, or do the following. Add chocolate chips and pecan butter to a medium microwave-safe bowl. This is the pecan butter I use. Heat in 20-second increments until chocolate is fully softened and mostly melted. Stir in between heating increments, until smooth.
Pour the chocolate mixture into the prepared muffin pan, making sure to evenly spread it across 12 cups. Tap the pan on a protected surface several times to smooth out the mixture and release air bubbles.
Chill in the freezer for 30-60 minutes, or until firm. Optionally, when the fudge is almost completely firm, press a pecan half gently into the top each cup. Enjoy! Storing instructions below.
