In the bowl of a stand mixer with the paddle attachment, combine peanut butter, butter, vanilla and salt.
Beat with the beater blade on low until well blended.
Add 3 cups powdered sugar, beating until blended.
Shape a scoop of peanut butter into a 1-inch or slightly larger ball. The mixture should come together smoothly. If it is too crumbly, add a touch more peanut butter. If it is too sticky, add a bit more powdered sugar.
Place the peanut butter balls on a cookie sheet lined with wax paper. Freeze for 30 minutes.
Place chocolate in the top of a double boiler. Pour 1 cup of water in the bottom pan of the doubler boiler and simmer the water on low. As the chocolate starts melting over the heat of the hot water, stir until the chocolate is smooth. Remove the double boiler from the stove.
Insert toothpick in peanut butter ball. Dip 3/4 of ball into chocolate, leaving top uncovered to resemble a buckeye. Allow excess chocolate to drip from the buckeye.
Dab the bottom of the buckeye on a piece of wax paper to remove excess chocolate, then place the buckeye on a wax paper-lined baking sheet.
Remove toothpick. Smooth over holes. Chill in the fridge until firm.
Our favorite peanut butter is either creamy Jif or Skippy.
*Feel free to use milk chocolate, or a mix of the two chocolates. Use high-quality chocolate so that it melts smoothly and easily. If the chocolate is too thick, you can add a tablespoon of shortening to thin it.*The exact number of buckeyes you will get depends on how big you roll the peanut butter balls. We roll our buckeyes about 1" to 1 1/4" in diameter. Refer to the article above for more tips and tricks.The calories shown are based on the recipe making 45 buckeyes, with 1 serving being 1 buckeye. Since different brands of ingredients have different nutritional information, the calories shown are just an estimate. **We are not dietitians and recommend you seek a nutritionist for exact nutritional information.
