I tried making a cake for the hubby years ago. I mixed the batter and poured it in to the pan. Yes, single pan. I didn't realized it needed to go in two (duh, it's a layer cake). So after the time was up I open the over and it's still not done. Then when I go to check it again it looks like a volcano...it rose in the center, cracked, and then the uncooked batter oozed out like lava. So, I left it in for a while longer, frosted it and voila! a really dense birthday cake. Hubby was nice enough to eat a whole slice. I have yet to redeem myself
