Jumbo Blueberry Streusel Muffins

I call this multi-purpose muffin batter my “master batter.” It’s a straightforward recipe to which you can add any of your favorite muffin extras. I personally love blueberries or juicy mangoes. The sky-high, soft, and tender muffins have that coveted bakery-style look to them. You can get that same finish by using a few of my secrets—baking at a high initial temperature, using enough leavener, and generously topping them with streusel, of course.
