As a soapmaker, I purchased for a few bucks some time ago a small software, called soapmaker, where you input ingredients with prices and units, and you may save recipes with these ingredients. It gives you percentages for each ingredients and you may switch through different weighing systems, you may scale the recipe and so on….. I thought that if it can be done with soaping ingredients, why not trying with cakes? It’s quite useful if you want to price your cake or if you wish to scale up or down: I enclose a screenshot, so that you may have an idea.
Hope this may help…..
Another thing I learned, and may be useful for who, like me has not chances to get the non stick spray, is this simple formula I found in internet, I’ve been using it for a while now and works wonders with bundt pans, while for regular 9 inch pans I also put a little flour:
The recipe is equal parts of crisco, vegetavle oil and flour, beaten in the KA until soft and fluffy. It can be stored “forever” in a glass jar. I use a brush to “paint” the pans, lol!
