My friend Penny passed this family receipe on to me. I haven't tried it yet.
I asked her why the quantities are so large. She advises that she makes a huge batch and freezes them in pretty, freezer containers (like Tupperware) and gives them away as gifts.

If you make it, let us know how it turns out.

Using mixer, mix 1 lb. brown sugar and 1 lb. of softener butter together until fluffy
Add:
1 lb. powered sugar
1 quart of vanilla ice cream
Nutmeg, cinnamon, all spice (to taste) – probably a teaspoon of each
Mix well.
Freeze.

When ready for a toddy, heat your mug, add a big scoop of above mixture, spiced rum (LOTS!) and finish w/hot water.

Drop in a cinnamon stick, sit back and relax – two of these are the best sleep drug there is!!
