Preheat oven to 400°F. Line a jumbo muffin pan with liners, set aside.
Combine both packages of Martha White Blueberry Muffin Mix and milk in a bowl until smooth.
Scoop the batter into the prepared muffin pan about 2/3 of the way.
Top with blueberries and streusel mixture.
Bake for 15-18 minutes or until a toothpick comes out clean.
Instructions for Streusel
Mix together butter, oats and brown sugar. *if you are in a crunch for time, you can also just place on on the top of each muffin separately before baking*

Notes
Crazy Busy Mama Tip:Want to make these muffins a little more filling for a better breakfast before school? Add some protein! Just use a premade vanilla protein shake instead of Milk or even a scoop of vanilla protein mix!
