1/2 c. mashed potatoes
1/2 stick butter
1/4 c. milk
1 tsp. vanilla
Powdered sugar to make dough consistency
Peanut butter

Potatoes must be cold (can use leftover mashed potatoes and leave off butter and milk). Add powdered sugar to potatoes, butter, milk and vanilla to form a dough that can be rolled out on an area dusted with powdered sugar. Spread peanut butter over rolled out dough then roll up like a jelly roll. Chill 1 hour and slice in 1/2 inch slices.
