Old Fashion Potato Candy

So one of my friends that i met in Hawaii posted something about potato candy something i have never heard of. so i decided to find out what it was. I found a recipe and decided to make it. The best part is that Potato candy is Gluten Free :D I found how to make it on The Merry Gourmet. 

here is what you need and how to make it: 

1 cup mashed potatoes, room temperature or cold
1/2 cup (1 stick) unsalted butter, room temperature
1 teaspoon vanilla extract
3 pounds confectioners sugar
1/2 cup smooth peanut butter, divided

Okay so in a large mixing bowl, stir together mashed potatoes, butter, and vanilla. Add confectioners sugar, one pound at a time, and stir together well. Once the dough is thoroughly mixed, divide it into two halves. On a sheet of wax paper, and using your hands, flatten out the dough into rectangle, roughly 12-14 inches long. (my daughter loved doing this part!) Spread 1/4 cup of peanut butter onto one half of the dough (i think it needed more peanut butter my self after i tasted it but the little one said she liked it as is). Carefully roll into a log and wrap well in wax paper. Repeat with other half of dough. Chill the logs for at least 2 hours before slicing. Once chilled, slice into 1/4-inch pieces and serve.

Make ahead: Store prepared potato candy, layered between sheets of wax paper, in the refrigerator in a covered container for up to 2 weeks.

Here is what mine came out to looking like:
