Reviews for Blueberry Oat Bars
Sort By :
"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!"
"AwfulI used fresh blueberries, and followed recipe exactlyNever 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."
"I hope this comes out of the oven better than it went in. Followed recipe but with a bit less sugar. Not enough mixture for crumb topping, had to make more. Not enough blueberry mixture for the 9x13 pan. Wondering what I did differently from those that gave 5 stars? Yikes! We'll see about this."
