Step 1

Preheat the oven to 375 degrees F. Spray a 7x11, 8x8 or 9x9-inch baking dish with cooking spray and/or line with parchment paper.

Step 2

First, make the streusel by mixing together the ingredients in a small bowl. Place in the fridge to harden.

Step 3

To a large bowl, add the eggs, milk, maple syrup, mashed banana, butter and vanilla; whisk to combine.

Step 4

Mix in the oats, protein powder, baking powder, cinnamon and salt.

Step 5

Fold in the blueberries, then transfer to the baking dish. Top with extra blueberries if desired.

Step 6

Take the streusel out of the fridge and crumble it evenly over top.

Step 7

Bake for 30-35 minutes or until the center is set. Let cool for 10 minutes before slicing. I like eating with Greek yogurt and a little drizzle of honey!
