I absolutely love desserts that can be served anywhere anytime of year. These Blueberry Cookie Crumble Bars are a hit for any occasion. They have a wonderful blend of textures and flavors.

Blueberry and almond pair so well together. These bars are a combo of gooey, chewy and crunchy. I am sure these will be loved by you just as they were by me and my family.

    My daughter and I are trying to be gluten-free. Would this recipe work with a gluten free baking mix flour instead of wheat flour? We love anything blueberry and this just sounds so good!!

    Hi, I enjoy your recipes and print out many. I liked this one, Blueberry Crumble Bars, because I like crumble for one and I had all the ingredients--which is somewhat unusual. I did note a small mistake though. In the filling first part it says sugar twice but not cornstarch. Anyone who read the ingredient list would know that that was in the filling. But just thought maybe you'd want to edit it. I intend to make it next week, right now anyone who would want to eat it is still denying themselves for Lent. So there it sits waiting...
    Thank you for your good recipes and enjoyable blog. I have also read about your family.

  3. Great for crafting!


    I gave this a go but it did not come out like yours. Why do my things always come out a lot less stable? Haha. It's just a bit crumblier than one would like. I know it's not the recipe because your pics look amazing. It's my inability to follow a recipe! Nevertheless, I was able to consume most of it while crafting over the last couple of days :) Naomi.

    these look amazing! i just wanted to check to see if the cornstarch and vanilla are added at the same time as the water and sugar to the blueberry mixture since it's not in the instructions. also, is 300 degrees the correct temperature?

    love your recipes!
