In the original recipe it called for unsalted butter and a mixture of AP flour and cake flour. I have been making them as above for 5 years and they are great!! If you want to you can use unsalted butter in place of the salted and use 1 1/2 cups AP flour and 1/2 cup cake flour.
These are the best blueberry muffins I have ever had!!
