In a large mixing bowl, add butter, creamy peanut butter, vanilla extract, and salt. Beat using an electric mixer until combined and creamy.
Add powdered sugar and beat on low until crumbly.
Using your hands, form 1-inch balls (about 1 scant tablespoon). Place them on a lined baking sheet. Place in the freezer for at least 15 minutes to firm up.
Add chocolate chips and coconut oil to a microwave-safe bowl. Microwave in 30-seconds intervals, stirring each time, until melted. Pour melted chocolate into a deep and not too wide dish. You can use a measuring can, a glass jar or a cup.
Remove peanut butter balls from the freezer. Dip into a melted chocolate using a toothpick. Don’t cover the balls with chocolate completely, leave a small circle of peanut butter uncovered on top to look like a buckeye.
Place the balls back to the wax paper and remove the toothpick. You can smooth over the toothpick mark with pads of your fingers. Refrigerate until ready to serve. Enjoy!
