Preheat the oven to 375 degrees F (190 degrees C), and lightly coat the inside of an 8x8 baking dish with Non-Stick Baking Spray (to taste). Set aside.
In a medium-size bowl, mix together the Old Fashioned Rolled Oats (2 cup), Baking Powder (1 teaspoon), Ground Cinnamon (1 1/2 teaspoon), and Sea Salt (1/2 teaspoon). Set aside as well.
Zest Lemon (1) completely.
Once zested, squeeze the juice from the lemon into a small bowl.
Melt the Light Butter (1 tablespoon).
In another medium bowl, whisk together 2% Reduced Fat Milk (2 cup), Maple Syrup (1/3 cup), lemon juice and zest, Large Egg (1), melted butter, and Vanilla Extract (2 teaspoon).
Add the wet ingredients to the dry ingredients and stir just until combined. Pour the mixture into the prepared baking dish.
Top the mixture with Fresh Blueberries (1/2 pint).
Transfer the baking dish to the oven and bake for about 35 minutes, or until the edges are browning and the middle is set. Remove from the oven and allow to cool for a few minutes.
Cut evenly into 9 squares and enjoy! Store leftovers covered in the fridge for up to 3-5 days.
