6, 8, 10, 12 Vanilla cake on a 18" square butterpecan cake. I didn't start this cake baking until 12:30 PM Friday for a 3:30 PM Saturday delivery. Had to change original design due to late payment so she got all of the cake she ordered but the design had to change to allow time to complete!!! I was pleased with it - not exactly what I had planned but her mom called today and said they loved it.
