Lemon Blueberry Sour Cream Crumb Bars May 5, 2014

Yep, I’m still at it.  The lemon blueberry combination has not gotten old.  I made this recipe for a work picnic, and they were a hit. I will let you know in advance, these are more blueberry than lemon, though.  I’d actually amp up the lemon flavor in them if I make them again for myself.  If you have a crowd that prefers the blueberry to the citrus, then it is probably right up their ally.  Personally, I love a good kick of citrus.  I actually added lemon zest to the crust, which the recipe didn’t call for.  It still didn’t come through enough for my liking if I’m expecting lemon.  The crust is deliciously buttery, which always makes for a good bar.  I found I needed to bake mine longer than the recipe called for, and the center kind of all melded together so it looked more like blueberry than sour cream/blueberry.  That didn’t bother me at all, though.  Also, it always seems like I don’t have as much crumble topping as the photo of the recipe I’m making.  I think people are secretly using more than they’re telling me on their blogs.  😉
