Bake that cake at 300 degrees...

For a moist cake, bake it at 300 degrees until it is set in the middle.  You can test by sticking a knife in the center.  If it comes out clean, it's done.  Also, oh so yummy if baked in a cast iron skillet.  This baked in one hour in my seasoned skillet that was sitting in an Air Bake jellyroll pan which keeps things from burning on the bottom.
