I have what feels like a stupid question but I am going to ask the experts anyway!! Can cake batter be frozen? If not, how long do you think it will stay fresh in the fridge? Thanks!!

Yes it can I don't know howto find it but IndyDebi started a thread about how she had extra batter she put into a pan & froze, then didn't even let it thaw when she baked it and all cam out right.
It can be kept in the frig (in the pan it will be baked in) for a couple of days.

Hmm I wonder if this will work with cupcakes too? I would imagine yes....

I saw someone posted (can't for the life of me think who it was) that they freeze cupcake batter in lined pans (lined with cling wrap I think) then pop them out and keep in a freezer bag till needed.

Cake mixes and most scratch bakers use double acting baking powder. What this means is that the baking powder is 1st activated when liquid is added, with a 2nd activation when heat is applied (during baking).

As a result, cake batter can sit without losing its ability to rise properly; it can also be refrigerated and/or frozen without losing its ability to rise properly when baked.
