In a mixing bowl, combine 1 cup of creamy peanut butter and ½ cup of softened butter; mix together until creamy and fully blended.
Next, stir in 1 teaspoon of vanilla extract to the peanut butter mixture for an extra layer of flavor.
Gradually add 2 cups of powdered sugar, mixing on low speed until combined, and be sure to scrape down the sides of the bowl as needed.
Gently fold in 1 ½ cups of graham cracker crumbs and 1 cup of crushed Butterfinger candy, mixing until evenly distributed throughout the mixture.
Scoop 1 ½ tablespoons of the mixture and roll them into balls. Place the balls on a parchment-lined baking sheet and freeze for 30 minutes to help them set.
Melt your dipping chocolate (either chocolate bark or chocolate chips) in a microwave in 30-second intervals, stirring until smooth, or use a double boiler method for better control over the heat.
Once melted, dip the chilled balls into the chocolate until fully coated, or leave some of the peanut butter mixture exposed. Top with additional crushed Butterfingers, colorful sprinkles, or a sprinkle of coarse salt for a delightful finish.
