Blueberry Crumb Bars Recipe

Blueberry crumb bars are an excellent way to use up fresh blueberries. One thing that I enjoy about this recipe is that it is fairly easy to make.  The process is very simple, a dough mixture is placed into the bottom of a baking pan, topped with fresh blueberries and the remaining dough mixture is then crumbled on top. These bake for about 45 minutes and you will be enjoying them in no time.

    These look simply delish ! I love the creamy glaze over top. I wish I could grab one right out of the screen !

    Thanks for all the recipes. I have tried several, and have filed many to ‘try’ soon.

    Bobby, What did you do for the glaze on top of the blueberry bars? I have followed your blog for awhile now. I love your recipes. Thank you for sharing and keep them coming!

  3. Bobby says:

    Ashlee Frisbey – Thanks for the compliments! I just whisked together confectioners sugar with a little milk and lemon juice.

  4. These look delightful, so full of juicy blueberries im sure they are dangerously addictive! The fact there is so much fruit in there basically means they are a health food and count as 1 of your 5 a day though…so this is fine 🙂

    Would love to give these a go, thanks for the lovely recipe!

    Just made these yesterday. They are delicious but i wish the cookie part was a little crunchier. Will be using less butter next time 🙂

    They look yummy. Going to try them today.
    I see you lined the pan with foil? Is that preferred over parchment paper?

  12. Bobby says:

    You can use whatever you would prefer. I have always used foil, it is just a personal preference.

  13. mary says:

    Just an idea. I am making these for the first time today. I hope for great results. But the glaze…..I am going to make the glaze but with a touch of lemon in it. instead of making the glaze with
    milk you would make it with lemon juice. That is my spin on it.
