The crust may look pretty crumbly as you work it, but it will start to come together and be packable in the baking dish. 

The bars should be baked on the middle rack, and they need at least 25 minutes to bake.

A dark brown baked filling topping is completely normal for these squares. 

The filling needs to be fully set before it’s cut into, or it will be runny and not cut cleanly. 

If you’re finding the filling sticking to the edges after it's been baked, glide and wiggle a butter knife against the edges of the baking dish.
