Excellent! Not the typical muffin mixing method, but the resulting batter was smooth and easy to drop into the muffin tins. I added probably about 3/4-1 tsp of cinnamon to the batter itself because I love it and it just made the muffins that much better. I also used 2/3 cup whole wheat flour along with 1/2 cup + 1/3 cup all-purpose flour. I think maybe I will use 1 cup whole wheat next time even because the spices are so great it may not matter! I got 12 muffins plus 6 mini muffins out of this batter and the tops puff nicely so they are very light and airy which is perfect!
