Scoop into 1 inch balls with a small cookie scoop or a spoon, rolling gently between your palms. Place on a baking sheet lined with parchment paper and chill for at least 30 minutes.
In a microwave safe bowl, add chocolate chips and coconut oil. Heat in the microwave for 1 minute, stir and continue heating for 20-30 seconds, mixing well in between heating until all the chocolate chips are melted.
Dip peanut butter balls into chocolate and carefully remove them with a fork and place back on the parchment paper. Repeat until all the peanut butter balls are covered in chocolate.
Place back in the fridge or freezer until the chocolate has hardened.
Store in a ZipLoc bag or air-tight container in the fridge for several days or freezer for several weeks.
