Peanut Butter Potato Candy

My nonna (grandmother) used to make these for Christmas. When I tell folks about this who are not from Appalachia or coal-producing regions their first reaction is usually to say "YUCK!" But I do think that this is really good---diabetic coma inducing really good, unfortunately---and I hope that someone out there will give it a try and enjoy it and pass it on. 

I lifted this recipe from Jerry Higgins on the "Scenic Harlan Co. and surrounding area" Face book page, but this almost matches the recipe that I have on hand.

ENJOY!     

Peanut Butter Potato Candy

1/4 cup unseasoned mashed potatoes
2 tablespoons milk
1 teaspoon vanilla extract
1 pinch salt
1 (16 ounce) package confectioners' sugar
1 tablespoon confectioners' sugar for dusting
1/3 cup peanut butter, or as needed

Combine mashed potatoes, milk, vanilla extract, and salt in a bowl. Stir confectioners' sugar into potato mixture until a dough consistency is reached. Refrigerate dough until chilled, about 1 hour. Sprinkle confectioners' sugar on a cutting board or waxed paper.

Roll dough into a large rectangular shape on prepared surface. Spread enough peanut butter on top layer of dough to cover. Roll dough into a jelly roll shape; refrigerate roll for 1 hour. Slice dough into pinwheels to serve.
