In the yogurt container (or transfer to a bowl), mix in the protein powder and PB2. Stir well until completely smooth.
In a small microwave-safe bowl, melt the chocolate chips and coconut oil in 30-second intervals until smooth (can also be heated over a double boiler).
Sprinkle half the peanuts over the yogurt mixture. Pour the melted chocolate over that and sprinkle the remaining dry-roasted peanuts on the chocolate.
Place in the fridge or freezer for 5-10 minutes, until the chocolate shell hardens and Enjoy!
