I made a birthday cake for my Mom and I wanted to make an icing that wasn't so boring, and went well with a butter pecan cake and I stumbled upon a VERY tasty icing that was absolutely perfect for my Mom.
Penuche Icing
1/2 cup butter
1 cup brown sugar firmly packed
1/4 cup milk
1 3/4 cup icing sugar
In a saucepan, melt the butter and add brown sugar. Bring to a boil and boil for about 2 minutes. Whisk constantly and add milk slowly, boil for another minute or so. Take off heat and let it come down to room temp/ don't put in fridge.
When it's cool, whip in icing sugar until it reaches your desired consistency. Can add more or less icing sugar.
Ice, and enjoy!
