I made these bars last weekend but am just getting around to posting them now.  In the time between making and posting them, I think I have seen them pop up on practically every other food blog I read!  And for good reason – these little babies are DELICIOUS!  Not only that, but they are also ridiculously easy.  I took Andrew for a visit to my dad’s work to show him off and brought these along for all the teachers and staff.  I saved a few at home for us, and quickly polished them off.  As soon as they were gone I was really, really wishing I had saved more – or maybe just made a double batch :-)  So if you are one of the few people left who haven’t tried these yet, make them while blueberries are still cheap and in season!  You will be very glad you did.

Blueberry Crumb Bars


1 cup sugar

1 tsp. baking powder

3 cups all-purpose flour

1 cup cold butter

1 egg

¼ tsp. salt

zest and juice of one lemon

4 cups fresh blueberries

½ cup sugar

4 tsp. cornstarch



Preheat the oven to 375°.  Grease a 9×13” pan.


In a medium bowl, stir together 1 cup sugar, flour and baking powder.  Mix in salt and lemon zest.  Use a fork or pastry cutter to blend in the butter and egg.  The dough will be crumbly.  Pat half of the dough into the prepared pan.


In another bowl, stir together the sugar, cornstarch and lemon juice.  Gently mix in the blueberries.  Sprinkle the blueberry mixture evenly over the crust.  Crumble remaining dough over the berry layer.


Bake in preheated oven for 45 minutes, or until top is slightly brown.  Cool completely before cutting into squares.
