Easy Blueberry Crumble Bars

You’ve arrived just in time to enjoy some easy blueberry crumble bars. These gorgeous little treats are bursting with luscious summer fruit and a buttery, crumbly crust. I borrowed the recipe almost verbatim from a recent post by Smitten Kitchen –I’d been looking for a way to use some leftover blueberries and these looked so good I couldn’t resist. I swapped in one third whole wheat flour — just to see what would happen (good things).
The bars came together quickly — simply combining the dry ingredients, cutting in the butter and egg and pressing half the dough into the pan. Dump in the lightly sweetened blueberries and top with the rest of the crumbly crust. A bake in the oven and ta da. They slice more easily cold, but good luck waiting for THAT! Out of the oven, the aroma is positively heavenly.

So, sit down, pour yourself some coffee or a glass of milk and have some dessert (or breakfast).
