1/2 cup margarine
1/4 cup milk
1/2 tsp. vanilla
2/3-3/4 cup of icing sugar
- Bring brown sugar, margarine and milk to a roiling boil in a medium sized pot on med-high. Boil for 2 minutes (start timing after it gets to the point that you can't 'stir away' the boil).
- Take off heat and add in vanilla and icing sugar. Mix well.
- Stir until starting to thicken and then pour over cake while icing is still warm.
- Scrape leftover icing out of pot with a spoon, while kids and husbands are not looking, and EAT! (don't burn your tongue though or you may be forced to explain)
