I am not sure if this has been mentioned on the many threads about using the 9 oz cake mix for the Mock Lemon Mer Cake... I don't have my SB with me, but I am thinking the Carrot Cups used a 9 oz box too. If this is so, then I am going to split the 18 oz box and use half for the Mock Lemon Cake and half for the Carrot Cups! Can anyone verify that they both use a 9oz box of yellow cake mix? (Originally, I was planning on just doubling the recipe so I could use the 18 oz box and make the 2nd torte and just freeze it for later. But, I don't have room right now in the freezer. ) See, this is what I sit and think about at work!!
