Use a toothpick to dip the peanut butter balls into the chocolate, leaving the top 1/3 undipped.
Chill to set the chocolate and enjoy.
Notes
Peanut butter: You'll want a smooth peanut butter like Jiff or Skippy, not a natural peanut butter, for this recipe.
Butter: If you'd like to use unsalted butter, add a couple of pinches of salt with the butter. The salt helps to balance out the flavor of the buckeyes.
Chocolate chips: If you'd like sweeter buckeyes, use milk chocolate chips. If you'd like less sweet buckeyes, use bittersweet chocolate chips.
