Wow! Many thanks to Dawn, Loriana and Alice for sharing their wonderful matrices! I know they put in a great deal of hard work on them. My only issue is that I don't use box cake mixes; I bake from scratch, so I'll have to add extra ingredients to each matrix. I just hope I can figure out how to add to and/or change the formulas without screwing it all up! LOL
A special thanks to Alice and Lisa (Loriana) for going into more depth regarding cake sizes and other baked goods. I'm just starting my business, but I plan to specialize in smaller desserts such as cupcakes, cookies, and individual items like mini tarts, cheesecake pops and cake pops. I've just been asked to submit a bid for the very first time, and I have absolutely NO idea how to calculate, what to charge, etc. Once I figure out how to use these matrices, I should be good to go!
