Easy 3 ingredient old fashion potato candy (no bake) is such a delicious and addictive treat – perfect for peanut butter lovers and neighbor gifts!
1 small potato (should fit in a 1 cup measuring cup, you can also use half of a medium potato) peeled and cut into 1-2 inch pieces (alternate option: 1/2 cup plain mashed potatoes)
6-8 cups powdered sugar
2/3 cup peanut butter (or cookie butter)
1/2 teaspoon vanilla (optional)
Place potato in a smal pot, cover with water, and boil until very tender. Drain and transfer to a large bowl. Mash (or use a hand mixer) until smooth and lump-free.
Add 4 cups powdered sugar and mix until blended (will be a sticky mess and this point). If opting to use vanilla, mix in now. Mix in more powdered sugar, 1 cup at a time, until mixture is very thick (slightly thicker than cookie dough).
Lay down a large sheet of wax paper and sprinkle generously with powdered sugar. Transfer candy mixture to the wax paper and sprinkle the top with more powdered sugar. Roll out to 1/4 inch thick rectangle.
Spread peanut butter evenly over candy. Roll tightly (long side toward long side), then wrap in the wax paper. Cut in half crosswise and put the two halves inside a large resealable bag. Seal the bag and chill for at least 30 minutes until firm, or until about 30 minutes before ready to serve.
Unwrap candy and slice into 1-inch thick slices and serve or store in airtight container, chilled, up to 2 weeks.
