This may sound a bit silly but I'm still not an expert at cake baking etc. I have a cake decorating class next week and I wanted to make a red velvet cake, the recipe I want to try uses oil and baking soda/vinegar mixture but no baking powder. Is it normal for it not to have baking powder and will it still rise?

Also the recipe calls for 3 eggs but that would make 10 cups of batter and all I need is about 5 cups so how do I deal with "halving" the egg content to make a smaller batch?

thank you, I appreciate any feedback as I would like to make the cake today and attempt the "freezing method" for the first time.

ABaking powder is baking soda, cream of tartar, and starch. Baking soda is sodium bicarbonate. Mixing baking soda and vinegar results in a chemical reaction that produces carbon dioxide bubbles that expand in oven temps and causes your cake to rise.

thank you very much :)

ANo problem

AYou can halve the eggs by weight using a kitchen scale or by volume or just use 2 eggs. Some purists would protest, but it'll be fine.

All the info. given you so far is absolutely correct.

I just wanted to mention that it's not unusual for recipes to only have baking powder or only soda. It's good that your looking at these things, to learn.....but fear not.

Thank you all for the responses!!!

I did make the cake and it rose extremely well!!! It's in the freezer so I haven't had a chance to taste yet but I really appreciate all the help
