This is bursting with more than blueberries - it is bursting with just wonderful flavors!! We love these muffins and can hardly refrain from "eating just one more". Perfectly written recipe - did not change one little thing and they were done completely in 18 minutes. Received 12 beautifully crowned muffins - love they all had nice tall crowns. Made for Bargain Basement tag game!! This recipe belongs on the top floor and no longer in the basement!!
