"I used three cups of blueberries, two cups of butter, added 1 tsp of cinnamon and 1 tsp salt. Would probably decrease sugar a bit next time. I thought it was delicious with these changes and would definitely make it again."

"First time making these there was not enough blueberry mixture for a 13 x 9 so next time I used 3 cups of blueberries, 3 tbsp of cornstarch and juice and the amount was perfect - also substituted 1/4 of the sugar using organic coconut palm sugar - my husband loves these bars frozen!"

"I used an 8x8 pan (so of course ended up tossing a lot of the crumb mixture ??) but otherwise this recipe is fabulous!!! Will definitely make again!"

"Can't seem to change my original one star rating. I'll give it 4 1/2 now. I needed to make more crumb mixture than what was called for. I added a bit of brown sugar, oats, flour and chopped walnuts to make the topping. Amount of blueberry mixture turned out to be perfect. I also used less sugar, about 3/4 of a cup total, for a less sweet taste. Really very good."
