In a stand mixer, add 1 jar of non-natural peanut butter with butter and mix until combined.
Add brown sugar and vanilla and mix.
Gradually add powdered sugar until combined. The more powdered sugar you add, the more crumbly the mixture. The less you add, the more creamy. We opt for more, as we enjoy a slight crumble to the peanut butter.
Scoop a spoonful of mixture into your palms and roll into a ball. Place the balls on parchment paper and freeze for 20-30 minutes.
While balls are in freezer, combine 2/3 bag of chocolate chips and coconut oil. Heat in the microwave and stir every 30 seconds until melted.
Add remaining chocolate chips to the melted chocolate and stir vigorously until all chocolate is melted. By adding cold chips to hot, you'll get a slight 'snap' to the chocolate with every bite!
Pour melted chocolate into a low drinking glass. You'll want the depth of the glass to coat the balls properly.
Remove balls from freezer, spear with toothpick, and dip 3/4 of the way into chocolate. Place on cookie sheet lined with parchment paper. Remove toothpick and smooth over toothpick hole (if you'd like).
Put cookie sheet in the refrigerator until hardened, then store in refrigerator in airtight container to enjoy whenever you'd like!
