Preheat oven to 350°F (175°C). Mash bananas until smooth.

In a bowl, combine mashed bananas, cake mix, pudding mix, and milk until well blended.

Pour batter into a greased baking pan and bake for 25-30 minutes or until golden brown.

Allow the cake to cool completely, then crumble into fine pieces in a bowl.

Mix crumbled cake with half of the remaining pudding until moist enough to hold shape.

Roll into 1-inch balls and place on a lined baking sheet; chill until firm.

Melt chocolate according to package instructions; dip each ball into chocolate and return to parchment paper; add sprinkles if desired.

Chill again until set before serving.
