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 on wax paper using some confectioners' sugar to keep from sticking. Spread peanut butter over dough and roll up in jelly roll fashion. Let sit 3 hours in refrigerator, then cut into 1/4 inch slices.
