Aunt Bee's Old Fashioned Potato Candy

Put mashed potatoes, vanilla, and salt into a bowl and add one cup of powdered sugar at a time, while kneading with your hands until mixture becomes a firm fudge-like consistency. You may need a tad more or less of the powdered sugar depending on how the mashed potatoes where made. Make adjustments depending on the texture of the mix, you’ll want it to be firm & dry enough to keep its shape but not too dry that would cause it to crumble. Divide the mixture in half, sprinkle work surface & rolling pin with powdered sugar and roll the potato candy into a 1/4 inch thickness. Spread a thin, but not too thin, layer of peanut butter on top, about 1/4 inch. If you use too much it will squish out the sides when rolling it up. Gently roll into a loaf and cover with plastic wrap or wax paper and chill for at least 1-2 hours hours before cutting into 1/2 inch thick slices (approximately 12 per loaf).
