Delicious and not too sweet. I used all of the crumb topping the first time but may scale it back the next time -- don't think it necessary to use the entire amount. Also, will try to toss the blueberries in flour before mixing to see if I can prevent them all from falling to the bottom.
It thought that it was tasty. It was not my favorite thing but overall was good. I did add more blueberries than the recipe suggested because I didn't want to have leftovers.
VERY GOOD!! and i really just dumped it all in one bowl and blended, (I don't like a lot of steps) the crumb topping especially was good and easy.
