1 lb. confectioners' sugar
1 stick butter
2 tbsp. sweetened condensed milk
1 tsp. vanilla flavoring
Peanut butter

Mix all ingredients, except peanut butter, together into a well combined mixture and roll out onto wax paper using some confectioners' sugar to keep from sticking. Spread peanut butter over dough and roll up jelly roll fashion. Let set 3 hours in refrigerator, then cut into 1/4 inch slices.
