Mini Blueberry Lemon Muffins with Lemon Icing

I was at the grocery store the other day and I spotted these bright yellow lemons, I didn't know what I was going to do with them yet but I just had to buy them.  After a few days I pondered on what to make when my roommate told me that he was in the mood for blueberry muffins.  So I decided to whip up a batch of mini blueberry lemon muffins because I think those two ingredients together have a great flavor combination.  The muffins worked out well, very moist and sweet with great tartness form the lemons.  The lemon flavoring isn't too overpowering and the icing gives the muffins a nice texture on top.  I would have liked it if the muffins browned more on top for nice color but it worked out ok because of the icing on top anyway.  I got the recipe from TheKitchn.com, modified it slightly, and posted my half version below.
