Gloppy, gooey and cooked to too high a temperature.
I also must make mention that lining the pan with parchment paper is crucial, particularly if you'd like to invert the cake without tearing it all up. I skipped that all important step; see Exhibit A and B.
I hurriedly cut a few rectangular pieces before the topping hardened to a crisp, and those made it into the final photo shot. I had to sample the mangled parts and I must say that this is a fantastic glazed apple cake. I will definitely be making this again!
All's well that ends well.
