Don't ask me how these things happen...why there would be two left over brownies sitting in our fridge for a little longer than necessary. Have no fear, there is always a way to use food items that are on their last leg! In this case, just throw two old (or not so old brownies) into a blender with some milk and ice cream and within minutes, you'll be downing a most supreme milkshake. Your welcome ^.^
