Blueberry Coffee Cake Muffins

These muffins literally disappeared within 10 minutes after taking them out of the oven. Seriously. We all really loved them, especially the kids. The muffins were filled with sweet and juicy blueberries and topped with a tasty streusel crumb topping - perfection! Simple to make and a delicious and tasty breakfast treat. I look forward to baking these again!
