Just threw together a sour cream pound cake from memory and put it in the oven. Cleaning up and thinking things are fine when... OMG
I forgot to put in the baking powder. Will the cake be okay?
Probably won't rise. Just a guess. And I think it would taste funny.
Let us know. You will be a guinney pig
I have several pound cake recipes that don't use baking powder....
My recipes call for lots of eggs, so the more eggs in your recipe the less noticeable the absence of baking powder. (The large quantity of eggs acts as the leavening.)
Your recipe might not rise as much as usual, but it shouldn't taste any different.. And being pound cake the texture is already dense, so that probably won't change much.
