In a large bowl, add the peanut butter, butter, and vanilla extract. Use an electric mixer on medium speed and mix until the mixture is fluffy.

Mix in the powdered sugar a little at a time, until all the sugar is added and completely mixed in. Cover the bowl and place in the fridge for 30-40 minutes to chill. This shows the perfect consistency, when you can form the mixture into a ball. If the mixture will not form into a ball add a little bit more peanut butter, and if the mixture is too wet, add some more powdered sugar.

Lightly dust your hands with powdered sugar, prevents the peanut butter mixture from sticking to your hands, then roll the peanut butter mixture into balls and place on a baking sheet lined with parchment paper or foil. Place in the fridge for 30-40 minutes to chill.

Prepare the chocolate for dipping using your preferred method, microwave or double boiler, you will need enough chocolate, about 10-12 oz so you have enough to coat all the candies.

When the chocolate is melted and the peanut butter balls chilled, place a toothpick in each ball and dip in chocolate making sure not to coat the very top where the toothpick is, so it looks like a buckeye. Remove the toothpicks and return the candies to the fridge to chill before serving.

Or just coat the whole ball in chocolate.
