Line a rimmed baking sheet with parchment paper.

In the bowl of a stand mixer, add confectioners' sugar, peanut butter, butter, vanilla, bourbon and salt. Mix together with the paddle attachment until smooth, approximately 1 minute. Fold in Rice Krispies.

Portion out the peanut butter mixture into 1 Tbsp balls. Roll the balls into circles with your palms. Add to the lined baking sheet, cover with plastic wrap and chill in the freezer until firm, approximately 30 minutes.

Before the balls are done chilling, melt the chocolate. In a small microwave-safe bowl, melt chocolate in 15 second increments, stirring in between until the chocolate is melted.

Coat the buckeyes to your liking, whether covering them completely, dipping to coat 3/4 of each, or drizzling chocolate on top.

Once finished coating the buckeyes, add them to the refrigerator until the chocolate is set, approximately 30 minutes.
