    The cake isn't sweet enough and frosting way to thick to spread. Threw in the garbage.

    Made this cake when my kids were young and forgot about it for years. Uses stuff we normally have in the cabinet and is real easy and tastes great. The brown sugar frosting takes this cake to the next level. Yum.
