(I always use my pie shields when I bake so the ruffled edges don't get too crispy.)
The streusel topping was amazing - however it still looked a bit "powdery" when it first came out of the oven. I think that particular spot didn't have a butter crumble. It eventually melted into the topping and it sure tasted just fine.
It was soooo good warm out of the oven. I even have a piece leftover today for Post-Thanksgiving-Monday-afternoon-snack.
