Preheat oven to 350°F (175°C). In a bowl, mix cake mix, pumpkin puree, melted butter, and eggs until smooth. Pour into a greased baking pan and bake as per package instructions until golden brown.

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

Gradually mix in powdered sugar until the mixture is moist but not sticky.

Roll the mixture into 1-inch balls and place on a parchment-lined tray.

Melt chocolate candy coating and dip each cake ball halfway using a fork. Allow excess chocolate to drip before placing them back on the tray.

Before the chocolate sets, add sprinkles if desired and let them cool until hardened.
