A perfect blueberry muffin! I made a few changes, simply due to personal preferences. I substituted some whole grain flour for 1 cup of the all-purpose, and used 1/4 cup applesauce + 1/4 cup butter for the 1/2 cup butter called for, and omitted the nuts in the streusel topping. These were so delicious! Made and reviewed for Aussie/NZ Recipe Swap #15.
