Blueberry Pecan Bran Muffins with Spiced Streusel topping

Oh bran muffin! How I love thee so!! The muffin that brings me such joy with your moist goodness and everlasting texture!
I made bran muffins last Sunday to have throughout the week. They were deeeee-licious. There were so many flavors that came forward in every bite! Sometimes I would notice a hint of orange, a light flavor of molasses or come across a nice juicy blueberry. Yum.
The best part about making this muffin was that I learned the importance of flour being present in streusel topping. My first batched had everything in it except flour and it melted right into the muffin. That made it have a nice sweet surprise in the middle, which isn't a horrible mistake in my opinion.
The second batch I added flour to the streusel-like mixture and it looked sooo much better.
I used Joy of Baking's Bran muffin recipe and added 1 cup of dried blueberries and 1/2 cup coarsely chopped pecans.
For the topping, I didn't measure anything, but it is made up of butter, brown sugar, cloves, cinnamon, nutmeg, rolled oats and flour. I'll have measure it next time I make it, which I hope it is quite soon!
