Hi! I was off the other day and one of my coworkers made a batch of 9" coffee cakes. usually they turn out great but this guy hadn't done it before and no one was there to help. When they came out of the oven, the sides had risen up and over the topping, creating a ring of batter all along the edge, covering the pecan topping. Since i was off, I didn't see what he did, and couldn't tell him for sure what he may have done and really not even sure what it could've been. Any ideas? Thanks a ton!
