In the bowl of a stand mixer fitted with the paddle attachment, beat the peanut butter and softened butter on medium speed until well combined.
1 cup creamy peanut butter, 4 tablespoons unsalted butter
Add the vanilla and mix to combine. Scrape down the sides of the bowl as needed.
1 teaspoon pure vanilla extract
With the mixer on low speed, slowly add the powdered sugar and graham cracker crumbs.
1 cup powdered sugar, ¾ cup graham cracker crumbs
Add the crushed butterfinger and fold it gently into the dough.
½ cup crushed Butterfinger candy bars
Line a large baking sheet with parchment paper and scoop out 1-tablespoon-sized portions.
Roll the buckeyes into smooth balls and then place them in the freezer to chill completely– about 30 minutes.
When the buckeyes have chilled, melt the chocolate bark in a microwave-safe bowl.
8 ounces chocolate bark
Dip the buckeyes into the chocolate, covering them either partly or all the way– however you like your buckeyes!
While the chocolate is still wet, sprinkle over additional crushed butterfingers or flakey sea salt. Allow the chocolate to set completely and enjoy.
