Cook the Potato: In a medium pot, bring water to a boil and cook the cubed potato until tender, about 10-15 minutes. Drain and mash the potato until smooth. Allow it to cool.

Make the Candy Filling: In a large mixing bowl, combine the mashed potato and softened butter. Stir in powdered sugar, shredded coconut, and vanilla extract until everything is well combined and forms a thick dough.

Shape the Candies: Scoop out small portions of the mixture and roll them into balls or log shapes, about 1 inch in size. Place them on a parchment-lined baking sheet.

Chill: Place the shaped candies in the refrigerator for about 30 minutes to firm up.

Coat with Chocolate: In a microwave-safe bowl, melt the semisweet chocolate chips and vegetable oil together in 30-second intervals, stirring between each, until smooth and completely melted.

Dip the Candies: Once the candy centers are firm, dip each one into the melted chocolate, ensuring it’s completely coated. Return the dipped candies to the parchment paper.

Chill Again: Allow the chocolate coating to set by chilling the candies in the refrigerator for another 30 minutes to an hour.

Serve and Enjoy: Once the chocolate is set, your Maine Potato Candies (Needhams) are ready to be enjoyed!
