This is a very light, moist cake....great for summer. The recipe came from Southern Lady magazine. I baked one last night to take to Sunday School this morning....4 pieces are already gone and we haven't left the house yet. Make this one a day before you need it....it's better the second day. If you can't find an orange cake mix, use white or yellow and increase the extract to 1 tsp. You can also use more mandarin oranges if you like.
