After finally getting our kitchen back in working order I got back to baking. I missed it so much, you don't realize how much you much using your whisks and cake pans. One of the first things I baked were these muffins from the Joy the Baker cookbook. I can't say enough good things about this book, it's been out for awhile now but I still love thumbing through it and picking out something to make.
Besides the blueberries, the browned butter is the other major flavor going on. Browned butter makes almost anything better. The first time I made it I burned it, it was blackened butter - not as good. However, when you don't burn it it's awesome and makes everything taste better.
They're super easy to make and especially right now when blueberries are in season (you can use frozen too).
