Colleen's Caramel Icing

I got this recipe from a friend on Facebook... Thanks Colleen!! ....it sounds delish!!! I will try this soon!!

2-1/4 C. brown sugar
6 Tbsp. butter or margarine
6 Tbsp. milk
2 tsp. baking powder
1 tsp. vanilla extract

Put the brown sugar, butter and milk into a medium saucepan and cook on medium heat until it starts to boil. Then boil it for 2 minutes. Remove it from the stove and add in the vanilla and baking powder. It will foam up a bit at this point from the baking powder and it's color will start to be lighter. You want to beat this with a spoon (I ALWAYS use a wooden one) in a motion like you're whipping eggs. Kind of tilt the pan and whip/beat it. We're looking for it to start holding it's own shape in the pan. This can take anywhere from 5 to 20 minutes. Once it starts to thicken up, check frequently with your spoon to see if it's holding it's shape. As soon as you see that's it's got a good hold, pour it quickly and spread onto your cake as it will set up extremely fast on you. If it comes out just right, it will have a slight candy-like texture. If not, it will be very soft and almost a caramel sauce on the cake (which is not bad either).

2 notes: 1) You only want to make this on a day with low humidity as it doesn't set up well otherwise. 2) This is one of those recipes that you just learn by practice exactly where that line is that it needs to get poured and spread. It took me a long time to be able to make it just right. LOL!
