Why does my crumble sink?

Chef's answer
the batter had swallowed up the entire amount. it turned out the oven was way off and the baking time was too long. the structure of the cake has to set quickly to hold the crumb topping up. my coffee cake uses sourcream which makes a more acidic batter which also helps to set the structure.
