Preheat oven to 350°F (175°C). Grease and flour a baking pan as per package instructions for the cake mix. In a mixing bowl, combine the cake mix, eggs, vegetable oil, and water. Beat until smooth and pour into the prepared pan. Bake according to package directions until a toothpick comes out clean.

Allow the cake to cool completely on a wire rack.

Crumble the cooled cake into fine pieces in a large bowl. Mix in peanut butter until fully combined.

Roll the mixture into balls about one inch in diameter and place on a parchment-lined baking sheet.

Melt the chocolate wafers according to package instructions. Dip each ball into melted chocolate, allowing excess to drip off before placing back on parchment paper. Add sprinkles if desired.

Store finished cake pops in an airtight container once they cool completely.
