Melt half of the dark chocolate chips in a microwave safe bowl, and microwave in 20 second intervals at 50% power - stirring at each interval, until melted.
Spoon all of the melted chocolate into the muffin cups. Tip - If the chocolate isn't even on the bottom of all cups, pick the muffin pan up a few inches from the counter and drop it, or shake pan back and forth until all chocolate is evenly spread.
Put muffin pan in the freezer for 15-20 minutes.
In a separate bowl, mix ProtoLyte® and peanut butter together (will be somewhat of a dry mixture).
Spoon the ProtoLyte® peanut butter mixture into each cup and spread out with a spoon.
Shake and pick up/drop muffin pan until mixture is evenly spread over chocolate.
Place muffin pan in the freezer for 15-20 minutes.
Melt the remaining dark chocolate in the microwave using the same process in step #2.
Spoon melted chocolate into muffin cups, picking up/dropping and shaking pan until mixture is evenly spread into cups.
Place muffin pan back in the freezer for 15-20 minutes.
Serve immediately, or store in an air tight container in the refrigerator until ready to eat.
