Hiya

i have a 12 inch square recipe and i want it to be equal to 9 inch circle kindly tell me which formula to use and if anyone of you have a conversion chart of cake recipes from big quantity to small kindly do let me know

thanks

It would help to know how many cups of batter your recipe makes, as well as how many cups your pans hold.
I am tempted to advise you to make your recipe as it is written and bake up the extra batter (cuppie, smaller rounds or whatever) and just wrap the extras up in plastic and freeze. Then when you need a quick dessert, whip it out and there you are!

As the PP stated, you convert down based on the amount of cups in the batter as the recipe is written and how many cups you need, not on the size of the pans.
