Blueberry Buttermilk Muffins Streusel Topping

I was on another quest recently. This time for muffins and this blueberry muffin recipe is really great! It was moist and full of flavor and you really should try it! I got the cookbook out of the library but also found it on another blog site. It was from Carole Walter's book " Great Coffee Cakes, Sticky Buns, Muffins & More". I halved the recipe as I usually do if I am testing it out. And I used a bigger and more shallow muffin pan so I would have more room for the topping. Happy Baking!!
