Blueberry Crumble Bars

Blueberry Crumble Bars are full of tangy blueberries with a hint of lemon atop a rich, shortbread crust and covered in a delectable, crumbly topping.

July is blueberry season, and Mr. SB picked up a huge container at Costco which ended up in the back of the fridge. Luckily I caught the berries before they went bad! And, even luckier, I found Deb Perelman’s (of Smitten Kitchen) recipe for Blueberry Crumb Bars to make a batch of delicious creations – think rich, short-bready, crumbly with a deep blueberry scrumptiousness that tastes like a summer’s day.

A few notes

Blueberry crumble bars were easy to make too, and will be part of our shore picnics for the rest of summer (if they make it past breakfast). I adapted the recipe slightly. As I made these in the evening I was feeling a bit lazy so I used bottled lemon juice and skipped the zest. I am sure it would be that much better if I used fresh lemon juice and took the time to grate the zest. Good news – the bars are unbelievable even with this shortcut.

I also ran out of granulated, white sugar so I had to sub in some brown sugar which actually I think added some depth. I also love a touch of cinnamon with any fruit dessert, and the amount I add does not clash with the lemon at all. And I used an entire egg. Part of me hates wasting the egg white when recipes call for just the egg yolk. Thriftiness took over this time and again, the results were amazing.

I refrigerated the bars overnight, and then took them out so they were room temperature for breakfast. I had a cup of coffee with mine on the deck. The girls each grabbed one too as part of breakfast. Great way to start the day – or end it. There is no bad time for a blueberry crumble bar!

  • Allow to cool fully to room temperature and ideally put in the refrigerator to chill . Then lift the bars out of the pan using the aluminium foil overhang and cut into squares. I used a pizza cutter which worked well. I also let the bars warm to room temperature which really brings out the flavors.
