Blueberry Crumb Bars

Have I mentioned to you how happy I am that “good weather” is  finally here?  It’s that time of year for us here in Wisconsin when the grass is a deep green and it’s not just the skies that are blue.  These luscious blueberries are laced with Ghiradelli chocolate and sandwiched between two layers of a soft flour and butter based crumb.  Tailor made for summer, these blueberry crumb bars are a recipe that you will not want to miss.

As I grow older, there is one thing that becomes more apparent every day: simple is best.  These bars are an excellent example of this mantra,  and they have one additional quality.  The are very delicious.
So, maybe I decided to mix in a little chocolate in with these fresh blueberries.  Do not judge me.  They’re still simple, and in my slightly biased opinion, even more tasty.   Now that we’ve established these bars to be simple and tasty, let me make just a couple of more points about them.
They are a true crumb bar.  Perhaps it’s not an overstatement to say they are a perfect crumb bar.  That is to say, these bars manage to hold their shape very well, in spite of their crumb base.  And now the good news and bad news about these babies.  I’ll give you the good news first.  They are not overly sweet. The bad news, as Scott pointed out, this attribute only make it easier to eat more of them.   Myself, I’m not entirely sure why that is not a good thing but according to the other man of the house, it is factor to consider.  (Once again) myself, I will accept the risk and because these are really really good, you might want to consider doing the same.

    My biggest problem would be to let them cool before I started eating them (as in plural)–these really look good. I love fruit which is why I prefer pies to cake!

    Oh these look good! I can’t wait to try them! Unfortunately I have to wait until after my baby is born because I have gestational diabetes and can’t eat any sugar or white flour right now :(

    Oh god. I’ve been so good at controlling my sweet tooth and watching what I eat, and now I think you just blew it. Thanks. These look really really good. Do you think if I share them with my family on Sunday it will negate the calories?

    Thanks for sharing at The Weekend Social. Looking forward to seeing what you have for us next week
