Thanks. I made a similar cake some time ago and for some odd reason it didn't go over. Maybe yours is moister. I'll try after yom tov.
Meanwhile, last night I made the choc. cake though didn't taste it yet. With all the soda and powder, once I started spreading it was obvious that a brownie pan would be too small. Two maybe? I still wasn't sure the 9x13 wasn't TOO much so I crimped the foil for the last two inches, then it became obvious that 9 x 13 would in fact be appropriate. And it was done after about 33 minutes. I'll do a taste test soon.
