Take the 2-minute tour ×  I added too much water in my box cake
mix and I already mixed the 2 together. What can I do to save
the cake? Could I add another box of cake mix to the batter?
share|improve this question Wait, if you have an extra box of
cake mix, just discard the first one and start over. Its not
like we're talking expensive ingredients here! –  derobert Jun 6

just make two cakes, without adding water for the second one. –

what we need to establish first is whether the OP knows exactly
how much extra water was added. If it was an accident and the OP
has no idea how much extra then starting from scratch is
prudent. If the OP knows exactly how much water added, then make
a double batch by adding more water to double the batch. –  Jay
