Description
A nostalgic Depression-era treat that combines mashed potatoes, peanut butter, and powdered sugar for a surprisingly delicious candy. These sweet rolls are sliced to reveal a beautiful swirl pattern.
Ingredients
Scale
For the Crust:
- For the dough:
- 1/2 cup mashed potatoes (cooled, no butter/milk added)
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
- 4 cups powdered sugar (plus extra for dusting)
- For the filling:
- 3/4 cup creamy peanut butter
- 2 tablespoons powdered sugar
- 1/4 teaspoon cinnamon (optional)
Instructions
1. Prepare the Crust:
- 1. Prepare mashed potatoes (ensure they’re completely cooled and free of any butter/milk).
- 2. In a large bowl, mix mashed potatoes, vanilla, and salt until smooth.
- 3. Gradually add powdered sugar 1 cup at a time, mixing until a stiff dough forms (about 4 cups total).
- 4. On a powdered sugar-dusted surface, roll dough into a 12×10 inch rectangle.
- 5. Mix peanut butter, 2 tbsp powdered sugar, and cinnamon (if using) until smooth.
- 6. Spread peanut butter mixture evenly over dough rectangle.
- 7. Tightly roll dough lengthwise into a log, using parchment to help if sticky.
- 8. Wrap log in wax paper and chill for 2+ hours until firm.
- 9. Slice into 1/2-inch pieces with a sharp knife, cleaning between cuts.
- 10. Store between wax paper in an airtight container at room temperature.
Notes
For best results, use russet potatoes. The dough should be play-doh consistency – add more powdered sugar if too sticky. Vintage recipes suggest letting slices ‘cure’ 24 hours for optimal texture.
