I don't have time to bake anymore, the closest I come to is making the
NoPudge brownie mixes (which are very good btw) but I do recall making this
chocolate uding cake a few times.
My guess is that changing the pan size will be a big problem, actually a
smaller pan may take LONGER to cook through as it will be thicker, but that
may toughen the cake part for this recipe. I recall overcooking it once
and feeling it was a bit chewy :-) Also I do recall decreasing the sugar &
water a bit. And use the best cocoa you can find, it always makes a big
difference.
The best fatfree chocoate cake I recall from the list was labeled something
like "Grandma's best chocolate cake". Sorry I don't have the recipe online
but surely it's in the archives.
