I am planning on making the Lemon cake and the Orange Dream. If I am going to do a 10 inch and 8 inch how many recipes of each do I need to make. It is probably going to be the orange as a 10 and the lemon as the 8.
When I have used Macmom's recipes, one recipe has given me enough batter for 2 9x2 layers plus 6-12 cupcakes. If you are using the 2 cake mix, 2 cups of flour, 2 cups of sugar base recipes, I think one recipe of each will give you plenty for the 10" and the 8". I actually did a half recipe when I did the 8 inch.
I haven't done a 10 yet but I think it will be enough batter.
