Nutella, sugar and potatoes are all items that can easily be acquired from the grocery store, but you'd hardly expect them to go together—unless you're making potato candy.
Although traditional Irish potato candies can be made without the root vegetable, this recipe from the Cupcake Project blog is truly made with a boiled potato. The soft cooked vegetable is coated in sugar and rolled in a nut butter before it can be cut out with a fun cookie mold shape. The Cupcake Project describes that these unusual soft candies have the "Consistency of fudge and taste like Nutella with the sweetness of white chocolate!" For a festive St. Patrick's Day twist, these candies have been cut out with a shamrock shape and coated in green sugar sprinkles.
