I have a bunch of sour cream I need to use up, so I'm thinking of adding it to the practice cake I'm about to make. How much sour cream would you add to one box mix? Also, do I need to change anything else, like adding fewer liquids?

Thanks!!

I always add a cup of sour cream

Wow, a CUP?! I always add 1/4 cup to my boxes and makes it perfectly moist. I added more once and my cake seemed 'wet' to me. Let us know how it turns out.

I use 1 Cup. Hope this helps!

I use one cup when I'm using the following recipe. It provides a sturdy yet still moist cake without the work of mixing from scratch. HTH

I use 1/2 cup of sour cream and insted of water I add milk

Thanks everybody! I think I'll add 1/2 a cup this time and see how it goes.

I also always add 1 cup of sour cream. I think it makes the cake so moist, rich, and tender. Please let us know how it goes with 1/2 a cup.
