I haven't actually tried this recipe so I don't know how many it serves, but it's definately designed for making this stuff in bulk, like for a Christmas party. I'd guess it serves maybe 40 or so.
Ingredients:
1 lb butter
1 lb brown sugar
1 lb powdered sugar
1 quart vanilla ice cream
1 teaspoon allspice
1 1/2 teaspoons cinnamon
1 gallon rum
Directions:
1. Add all ingredients to rum. 2. Heat on the stovetop.
