What went wrong with this cake recipe? Was it the amount of baking powder?
I tried to make this orange olive oil cake with walnuts this weekend http://www.seriouseats... It called for 1 tbsp of baking powder, which sounded like a lot, and while baking the cake overflowed the pan and then collapsed. I think the baking powder was the cause, but I found another similar recipe (by Mario Batali) with the same ratio of baking powder. Thoughts on what went wrong?
